2026-02-02-ucsb-ml I am in the mechanical engr department and I actively use python for my work for geometric statistical analysis on cell shapes. My advisor now would like me to begin to incorporate ML with my geometric statistics…. so I am hoping to gain a better sense of what that really means, what it would look like, how ML models are actually built, and as an engineer, how I can implement/ build ML tools in python. :) Thank you for your time in. advance!

2026-02-02-ucsb-ml This workshop was SO incredibly useful and helpful. Both of the instructors (Jose and Tian) thoroughly offered all of my questions and provided useful one-on-one feedback and guidance. Both instructors were patient, understanding, and incredibly knowledgable. The pace was perfect and I appreciate how the instructors and helpers were both asking if we had questions throughout. this was by far the most useful ML class I have ever taken. I would take this every week if I could because I learned so much and it was so effective and useful. It will be directly relevant for my research. Thank you!!
2026-02-02-ucsb-ml they were able to answer some questions that people raised that were more specific to their expertise.

2026-02-02-ucsb-ml prompt assistance when in need & invitations to ask questions
2026-02-02-ucsb-ml Very helpful answering questions and going in depth
2026-02-02-ucsb-ml clearly answered a question that i had provided on my sticky note from day 1

2026-02-02-ucsb-ml The content was useful and applicable, the topic breadth was perfect, it was the perfect balance of application and theory, and the instructors were knowledgeable and patient.
2026-02-02-ucsb-ml it was a great exposure to some of the ML concepts and how to implement them in python. it gave me things to think about for how i might implement some of these things in my work, which is much farther along than i was before the course.

2026-02-02-ucsb-ml well-made jupyter notebooks
2026-02-02-ucsb-ml Good intro to libraries and setting up code to do ML analysis
2026-02-02-ucsb-ml Very clear and good balance of theory and practice

2026-02-02-ucsb-ml The only improvement would be to have more of these workshops because they were so useful!
2026-02-02-ucsb-ml it was rushed, but i think that’s alright to get people some exposure to the topic. they were very good at dealing with a number of different folks who had technical issues.

2026-02-02-ucsb-ml design it so that we could cover more of the image convolution material. a more useful intro o that could have been achieved with ~30 minutes.
2026-02-02-ucsb-ml pace could be a bit faster, maybe less specific details
2026-02-02-ucsb-ml If the code is mostly set to be run with no mods, spend less time going over coded and more time and theory
2026-02-02-ucsb-ml this is difficult with a broad audience, but it would have been neat to see more specific examples that would apply to my STEM research
