Very engaging class and interesting applications. Professor is extremely knowledge about course topics and always ready to help. Great class overall. One of the best in the Systems Engineering Masters track.

Excellent professor. I have taken all of the classes that he offers and enjoyed every single on of them.

Professor You is the most professional, most helpful, and most well prepared lecturer in my experience as a distance learner at Cornell. Very GOOD class!

Great professor. Very responsive to questions on piazza and by emails. Homeworks are the right level of difficulty to help us comprehend the material without placing an unexpectedly difficult burden/challenge on the students.

The professor was always available over email when I asked questions even on the weekend and was prompt to respond. I was very impressed by this. Every time I sent an email to professor You I received a response typically within 12 hours.

Projects were great way to learn and presenting helped to address any other aspects that we may have overlooked. Professor You is the best.

I loved this course. Incredibly interesting area of study. I felt compelled to learn more throughout. Having to complete a project really helped to learn the nuances as well on a practical level. Not only say we understand deep learning but that we've actually done development using deep learning, a critical distinction.

Deep learning and machine learning is done on the job where I work and would like to get into the field that is why I took the class. very good material and applicable to real world examples. Grading scheme and expectation for projects clear and fair.

Very timely assignment feedback and clarification to questions, especially with the weekends.

Took this course in the summer. Very reasonable workload. Assignments were a fair judge of applying knowledge and expectations were clearly communicated and reasonable.

Professor You is very engaging and makes himself available to help. I enjoyed the course and his lectures.

Hands down the best class I've taken at Cornell so far. Professor You is hilarious and very smart. While it's not an easy subject, You makes it very manageable and you will learn a lot of real world skills in this class.

An excellent course.

I am taking the course online due to travel concerns this semester. NO exam! Lectures are not mandatory to attend. Videos, piazza and office hours are very supportive. Very responsive replies to all my questions. Professor You rocks! The BEST CBE prof!

Second the best CBE professor at Cornell! There is no exam in this course, giving fair assessments through homeworks and project without the exam pressure. After Prof You learned that I am taking the course from a different time zone, he acted promptly to make attending lectures an optional choice by students. Very chilled and caring professor!

A five-star professor! Very speedy replies to emails; generous in grading and deadline extension; amenable to all requests; helpful in organizing teams; exceptionally supportive and patient. He is a good reason for us to study at Cornell. TAs are great as well. Highly recommend this course to all DL students!

I was attracted to the course because of the certificate, but I now find the course much more useful to my work than I expected. Optimization has many applications to all fields, and the professor did a good job to cover the applications without too much hard theory, while making the course interesting enough to challenge us. Abundant office hours.

You is the best professor Ive had so far, he is very caring and accommodating. Super easy grader. Insightful homeworks and fun in class lectures. He helped me a lot when I have questions after the class.

Amazing professor! Plentiful of office hours! Wonderful teaching support! Very responsive replies to emails and piazza. I plan to take all his courses at SYSEN distance learning program

Professor You is the best professor at sysen! After he knew that I am located in Europe and the evening office hours would be too late for me, he immediately added afternoon office hours to accommodate my schedule. The class is not so easy as some told me, but Professor You is always helping outside classroom making learning much easier.

Interesting professor and innovative teaching style. The assignment of developing a wiki is quite unique. I am fond of his course!

I am very appreciative to Prof You. He is a great professor and even a great person!

Very kind and helpful professor. Spend the whole Sunday afternoon helping me debug my code. Always very considerate and supportive. Thumbs up! I will take all his other courses next year.

I took this course remotely from a different time zone. the prof is very caring. he makes all lecture videos available and always replies to emails very fast. His lectures are well organized into 8 modules, and lecture slides have much better quality than other courses that I am taking. I feel that I learned a lot, especially on Python coding.

I took prof You's machine learning course in the spring, and this is my 2nd course with him. 6 HWs + 1 project + 1 optimization wiki. workload is reasonable and grading is fair. Similar to the spring course - very well organized and a lot of flexibility to choose the programming difficulty. I wish there were more courses with him that I could take.

This was one of the most beneficial courses I have taken. The lectures are very well organized, and Professor's' slides are clear and self-explained. Grading is quite fair. A lot of fun with coding. It should be mandatory for all Systems Engineers!

Given the topic, the content of the class provides a really good set of tools to tackle optimization and data science problems. Content was well structured and managed.

Prof. You learned our names and made an effort to extend help to anyone who needed it. The class was easy, even for those with no-coding background like myself. Learned a lot. The expectations aren't that high. If you take advantage of OHs and put in the effort on homeworks and project, easy A. Take his course if you can! Highly recommended!

My first course at Cornell. I like the Mr. You's style - very chilled, caring and flexible. I thought he would be upset after I told him I am less into ChemE and more towards CS, but he instead was very supportive and talked to me a lot about AI and data science. I will unlikely have him as my advisor after moving to CS. A great professor for ENGRG

The course slides are very well prepared and were all that was needed in order to be successful in the course. The homeworks are very good resources or student to better understanding the course material. The lectures are well-structured and very clear. I appreciated and enjoyed course material being presented with many real world applications.

Prof. You is an excellent instructor. His command in Optimization topic is outstanding. The course slides/materials are of high quality. Prof. has explained all the solving methods in detail and with examples. I can clearly connect these methods in Machine Learning, since machine learning is an enhancement of Optimization.

Professor You organized his lecture slides by topic so we didn't have to open a million different slide decks to find the material to study. He provided so many real life examples of the material and their model formulations so the content felt especially applicable, relevant, and understandable. Help was always available with the office hours.

Prof. You is the best professor I have had in my 22 credit hours of experience at Cornell. His lectures are engaging, course content is relevant and interesting, and gradings are fair. His focus on students and their success makes me appreciate my time at Cornell. He has set the standard to which all other course delivery should be measured.

I do not exaggerate but Professor Fengqi has exceeded all my expectations. We are talking about a TRUE teacher, who knows the subject, make you want to learn more and study. For assistance to DL students we are talking about daily support and care! In my eyes, he is a real top University professor and I feel very proud to be a member of his class.

I can tell that Professor You cares that the students are learning the material. I appreciated that he gave us so much freedom in the project as it really enabled us to think about what we learned this past semester and how to apply it in a meaningful way. The hws were relevant and challenged us to think outside of the examples shown in the class.

I don't think any one needs to take this Engineering Seminar course again, so the question of take this prof again is inapplicable. Prof You is very kind and caring. He spent a whole Sunday morning helping me with pre-enrollment and course selection. The course covers all aspects on college life. He is a much better prof than others I met so far.

Prof You was a great teacher and was great at explaining the concepts and their real-world applications. There was a lot of time allotted for practicing examples and asking questions, which I valued greatly and do not see often in other classes. The lecture forces you to think and understand instead of passively listen.

I found I could get a lot more out of this class during the summer than I could get out of those same class being taken concurrently with three others during the standard semester. This course is very good, and very well organized. I value most the lectures and recitations.

Given the topic, the content of the class provides a really good set of tools to tackle optimization problems. Content was well structured and managed.

This course is great. Professor You is awesome!

This class was intellectually challenging and the final project took me 25+hours but You is the best professor Ive had so far, he is very caring and accommodating. Super easy grader. Grading is super fair.

Took this course in the summer as an elective requirement for my CS major. The experience is much better than expected. Prof is nice and caring; rigorous content and well organized lectures. I like he provided slides on all details and interesting connections with data science. Take his course if you can and he teaches this ORIE course again

Professor You is an expert on optimization and even a better teacher. He know s how to explain difficult concepts well, and also draw real life applications to motivate the study. I had great experience with Professor You in this summer course, and wish he would offer more ORIE courses in the future.

Great professor, interesting topics, fair grading, abundant office hours and helpful TAs. A five-star course!

Homeworks could be challenging sometimes, but the TA and Professor are quite generous in offering time to help and in grading. No exam - an obvious plus. I live the group projects studying COVID-19 vaccine distribution - I wish my team could consider that topic. I plan to take the machine learning course next semester, and really look forward to it

The course content is really interesting and very useful. I feel like I learned a lot and am much more capable in the field of optimization, and at the same time the course wasn't very challenging as far as the workload or project were concerned. Take this class if you can!

Awesome professor and five-star course. I will graduate soon and won't take his course again. Take this summer course with Prof. You if you could.

Thank you for a great summer course, professor. And thank you for helping my graduate application. I hope to take your other courses in future years.

Nice professor. helpful course. helped me navigate the college life. hope I would have him as my professor in another course.

Absolutely one of the best cheme professor at Cornell! He is quite knowledgeable, caring, and supportive in may ways, while not as harsh as other professors in cheme design. It has been several years since I took his course, and he is very kind recently helping me on my PhD applications. Take his course if you can!

very engaging class, speedy replies to all my emails, flexible deadlines, abundant office hours. I had a great time at his class!

+1 great professor and five-star class!

World class support from the Professor and his 3 TAs in my humble opinion. Offers a Ton of office hours for different schedules and time zones for students. During office hours questions and explanation and extra help with a smaller audience is very helpful for the subject. Very useful addition of forum called ED. help is there if you want to seek

Professor Fenqi is committed to students success, makes an extremely complicated topic easy. Take all his course if you can!

The professor is so knowledgeable about the subject. I love that there are many interesting and actual topics discussed in the lectures . The grading is very fair and reasonable!

Professor Fengqi should be teaching other professors teaching techniques. I think the university will benefit a lot of having Professor Fengqi as couch to other professors and help them to successfully deliver their classes.

Dr. You is an excellent teacher and his light-heartedness is breath of fresh air compared to Uber-serious and dull lecturers Ive had in the past.

The class is recorded so I can go over the lecture at my own pace. Prof. and all the TAs are very supportive. The assignments help me connect real world implementation with the course material.

Even if I do not fully comprehend everything, I get an overall impression of what I am doing. I picked up two software and a broad range of concepts in ML. The homework assignments are really good for learning.

The professor is so knowledgeable about the subject. I love that there are many interesting and actual topics discussed in the lectures. Lectures very clearly explain difficult concepts in a manner that is understandable

Professor You does a great job of explaining even some of the more difficult concepts and does a great job of using graphics and charts to help visual learners. He has accommodated all the requests that I made. Professor and the TAs are also very quick to respond to questions on Ed and always try to answer our questions.

Great content and overall effective teaching with a hands-on approach to state-of-the-art machine learning techniques through projects. The professor is able to effectively break down difficult concepts for the students.

Dr. You's courses (1. Computational Optimization and 2. Big Data and ML) are the best courses I've ever taken. Dr. You is an outstanding professor that works to actively include all students in his classes. His expectations for understanding and knowledge are reasonable, and the content in his course is so well laid out and prepared.

The course gives very good overview of machine learning algorithms and introduction to using them in real life. An excellent one!

Four homeworks and one project. Reasonable workload and no exam. Professor placing heavy emphasis on project work greatly enhanced my learning of the material, especially vs. a purely exam-based course

Instructor does a great job condensing all the important information into one semester. A very useful course to take

Great course covering many topics on machine learning. I learned a lot. Projects are quite interesting. NO EXAM IS GREAT! Professor is very kind and flexible with deadline extension. I will take his course again in the summer.

I think it is a 4-star course. 1 star lower because of the kids in the classroom did not interact with the professor. prof has been working hard to engage them, but kids are dull. kids might be more interactive at in-person classes. however, this is nothing wrong about the prof. given many 5-stars, I run a clustering to group mine into 5-star also

I did not have coding and stat background before taking this course. The professor and TAs are quite helpful. Lectures are not mandatory, but I wish they were. The project piece is quite interesting and helpful. a good ML course to take

A great course for machine learning. I registered for his summer course for deep learning as well. workload is quite affordable that you could take another systems engineering concurrently with this one as a distance learner. Professor You offers great flexibility on deadline extension, etc.

As a ORIE student, I would say this course is MUCH BETTER than most ORIE courses that I have taken. I am glad that I chose this one with professor you. It covers many recent topics, as opposed to some ORIE courses that were updated after many years. ORIE students should consider this machine learning course!

this course requires coding throughout the course, but it was not mandatory to have prior knowledge to coding. The professor and TAs were very useful in walking through the code and guiding whenever needed. I feel this course is so helpful to my thesis research.

Course is well developed, from basic to very high level. Also, all the difficult topics in machine learning are presented in a simplified way, which makes it very easy to understand. The last few lectures on neural networks are amazing - I wish I had spent more time on those topics.

Good courses for M&A and Application electives. You will also get the data science certificate by taking his two courses. Dont miss his courses when you are in the program!

Great course - much better than the ORIE and CS ML courses that I have taken. It's taught by Zoom under the pandemic. Attendance is not required, so you could watch videos. Homeworks and project are quite practical. no boring proofs! No exam! The slots were taken very fast - I was lucky - grab a seat asap or you'll have to sign up for chem session

Great professor, fair grading, and much flexibility in deadlines. We need more professors like "You"

Got my first A+ at Cornell. feel pretty good. A five star course without saying!

Great course for System engineering students. I learned a lot. Grading bases on homework and project. Very fair and reasonable workload. Lectures have a lot of stuff to digest, but they are for good reasons. The field of machine learning is quite exciting and I'll learn more in the summer course with professor again!

There are five homework assignments, but the lowest score would be dropped. The course project is team-based. Workload is manageable. Materials and lectures are interesting and cover many details. A great choice

Fenqi is very helpful outside the class. TAs are great. I am happy with getting an A in this class. It would be better if I took the fall course before this one, but the overall outcome is good. I'll take the other course in the coming fall for sure!

Excellent course; excellent professor; excellent topic! No textbook, but the lecture notes are well organized and nicely illustrated - much better than a textbook.

Any one could take this machine learning course and suceed! I am a live example! No python experience and little knowledge on stat and optimization, but professor and TAs are quite helpful - many tutorials and office hours and giving me much courage to continue on this course and finally got an A. I am grateful to Professor You. HE IS THE BEST!

You is A TRUE GEM in Cornell Systems Engineering faculty! Great course materials on data science and machine learning! Student-centered pedagogy!

I really enjoyed the two courses in optimization and data science. Look forward the summer course on deep learning soon!

Best professor at Cornell Systems Engineering Graduate Program! Wanna become a data scientist and get a high GPA, take this course with Professor You!

Examples of application were extensive and applicable to all industries. Lectures were very through and interesting. Content was deep theoretically but had examples to show applications. Supporting, operational lectures were provided to help those students who had not taken prerequisite classes in a while which was appreciated!

I also took 5888 in the summer. Great lectures, helpful professor and TA, interesting material, and fair assignments/workload. I would definitely recommend the class to a friend. I'm very happy with the experience!

This is my first Cornell System Engineering course as a DL student located in Europe. The tools and skills I learned are very useful. I am actually utilizing those skills immediately in my job on reducing costs in our company. The professor is very accessible and TAs are great. Good course to take!

I like the way Pro You does not take attendance and offer much flexibility in assignment deadline extensions due to the difficult semester at Cornell University this fall. The course materials are not that easy, but the professor and TA worked hard to make everything accessible to us. It's an enjoyable learning experience overall. Highly Recommend!

If you a cs + math elective, sysen 6800 might be a part of your electives. Avg grade is A /A+. Of any of the courses offered by Prof Fengqi You. Easy A

I took the spring machine learning course before the optimization in the fall. it was a difficult start for me b/c of the prerequisite, but You is very encouraging and helpful. Akshay, the TA, is awesome! I dont encourage you to follow my reverse sequence, but if you have to do not worry - You would help and he is quite chill. Happy with my A+

its much easier to get the optimization one in the tall after the spring ML course. You and his TAs are very considerate. if you need help with problems or project, just ask them for help. You never said no to deadline extension and always replied very fast. He is a true gem in cornell systems engineering!

Nice professor much more accessible than many ORIE professors. He runs office hours on weekends and gave deadline extensions if you request. Although this is a chemistry course, it has nothing to do with chemistry at all! I do not know chemistry and I am happy with the materials. A much better course than the ORIE one! Will take his course again.

All the "rumors" are true, yeah - 5-star course and 5-star professor. Needless to say! Will take his spring course again!

You have been an absolute inspiration for learning the basics of machine learning. As someone who is interested in the field but has had little experience in computer science he has made the learning experience manageable and extremely valuable. It has encouraged me to continue thinking about pursuing a career in data science and analytics.

I am a full time employee and working a part time job. Having the ability to work on assignments without the stress of tight deadlines and no possibility of extensions greatly helped me be able to earn a good grade in the course. Thanks for the patience and flexibility throughout the class this semester!

One of the two courses for Computational and Data Science Certificate. A no-brainer choice to take. I look forward to the second one in the coming semester - heard most seats were taken in the pre-enrollment ... lol

Professor Fenggi is simply awesome. Tkae his class if you can!

Another great course by Professor You! The recent Fukushima nuclear disaster example is very inspiring. It looks like the workload this semester is actually lighter than the previous course (less homework and assignments). Look forward to the exciting weeks in the rest of this semester to come!

It's just been a few weeks, but I really like this course. Professor makes it very FLEXIBLE! No exam, no mandatory attendance! There are timely support and replies on Ed Discussion on various issues. No wonder the class is so popular and hard to get in. I appreciate the Professor sent me a quick email when a slot was opened to sign up.

Nice professor and easy ML course with no exam. Attendance not mandatory. Very effective use of electronic platform like Ed Discussion and Canvas. I like it!

Nothing more can be expected from an excellent course. Professor You is the best!! Take his course(s) if you can when you (and he) are at Cornell.

Nice professor and useful course. Take it if you could! I heard You will be on sabbatical leave next spring. Not sure if he will still teach in the fall.

The professor is very accessible, accommodating and knowledgeable on data science. He always teaches in the classroom even when there were very few students there. The TA Yvonne is unfamiliar with the subject. TA Bryan is much more knowledgeable about machine learning than Y. A great course but hopefully the TA would be better next time!

Great course, great professor, great TAs! Many office hours. The professor is highly experienced in teaching distance learning students and very accommodating. I plan to take his another course in the fall.

Nice professor. Always grant permissions for reasonable requests.

Great Professor. He is very much concerned about how you will be able to perform in the outside world when people know you have taken his class. I learned more in this class than any other SYSEN class that I had taken.

A wonderful machine learning course! I did not take 5800 in the fall, but the professor made an exception for me to try it out this term as he may leave Cornell next year. Super DL-friendly course! The best one in Cornell System Engineering. I hope other DL students could benefit from Professor You's classes while still here

Good course. Learn a lot about AI and machine learning. Highly recommended by my LM co-workers. I am glad I took it this semester.

Easy A professor. A truue gem in Cornell system engineering

Good course and supportive instructor and TAs. I will take his deep learning course in the fall to learn more. Very exciting!

The balance of the course was very enjoyable. The lectures covered a wide variety of concepts in the field, and the assignments/OH provided more of a hands on application of the material.

This my favoriate class I've taken at Cornell and hope it never changes. TA Akshay was amazingly helpful throughout this course.

I really value Dr. You for the flexibility that he extended to students like me, Distance Learners, in the office hours and deadlines.

Very interested topics and very timely. It covered ChatGPT and many LLMs.

Excellent curriculum for non computer science background people to transition into Machine Learning.

Homeworks were very useful and You was a generous grader. The best teaching professor at Cornell SE!!

This course was a perfect blend of theory and applications that no other machine learning course at Cornell could provide. Learnt a lot. Look forward to another course with Dr. You in the fall

The content is very inspiring, I could learn a lot from it. Instructors are very very helpful. Also, I learned how to do some application with what I learned in this class and got some basic understanding of the use of the machine learning methods.

The availability for office hours and the promptness of the professor in providing a schedule for office hours each week was extremely valuable.

An easy A course. Intelligent, well-spoken instructor (Prof. You); he took initiative to ensure that all students were enjoying class; Use of projects, instead of exams

I liked the learning through application, I felt like I learned a lot better by doing assignments and a challenging, creative project than by preparing for exams in other classes

Prof. You is a knowledgeable and supportive instructor. Took initiative to ensure students' enjoyment. Assignments and projects were valuable; unstuck AI was a helpful study tool. Reasonable workload, easy-to-follow content.

Ed Discussion was excellent. Lecture content preparation and delivery with high quality. Optimization Wiki was very helpful.

Even though I am a distance learner, I felt engaged in the classes which helped understanding the content.

Professor You executed the class with high quality. His course content was highly organized. The content in the lectures directly supported the concepts being taught and the homework assignments related directly to the lectures and discussions.

Very knowledge professor and TAs. Great outside class support. Exercises very applicable. Homework not overwhelming. Easy grader. If you get the chance to take a class with him, take a class with him!

Not an easy course, but you will learn a lot. Professor is very supportive, and grading is quite fair with reasonable workload. I'm so happy with taking both courses with him and earn the data science certificate as part of my Cornell Master's degree.

Took the course last fall as a distance learner. The extra office hours during late evenings, on weekends and also on need basis helped significantly in getting the required support and I am thankful to Prof. You and the TAs for the same.

As a distance learning student, I was impressed with how well the course was adapted. The asynchronous format worked great for my schedule, and the material didn't feel watered down at all.

Five star professor! Very responsive and accommodating.

Nice professor and very DL- friendly. Super responsive in responding to my questions

Lectures are clear and organized. Very understanding about end-of-semester stress. Dropping HW at the end really helps with the workload. Would definitely recommend!

Great course and interesting topics. Many emerging ones are covered.

I learned a lot from the course. The professor seems an easy and fair grader.

Interesting topics. Fair and reasonable grading

Easy short course interesting topics
