The Thesis Review [29] Tengyu Ma - Non-convex Optimization for Machine Learning
5 snips
Aug 1, 2021 Tengyu Ma, an Assistant Professor at Stanford University, dives deep into the intricate world of non-convex optimization in machine learning. He discusses the fascinating concept that all local minima are global minima, shedding light on overparameterization benefits. Tengyu also reflects on his transformative journey from theory to practical applications and critiques educational programs that balance theory with hands-on research. The historical evolution of optimization techniques and their implications for neural network design are explored, making this a must-listen for aspiring researchers.

Episode notes
Understanding Non-Convex Optimization
- Tengyu Ma aims to understand which non-convex functions can be solved and to what optimality.
- This involves characterizing functions and determining how quickly they can be solved.
Shift to Machine Learning
- Tengyu Ma's initial PhD interest was approximation algorithms, not machine learning.
- He shifted to machine learning after Sanjeev Arora's move, inspired by the field's potential for realistic algorithms.
Yao Class Experience
- Both Tengyu Ma and Donxi Chen were in the Yao special class at Tsinghua University.
- The class had an advanced curriculum, research opportunities, and fostered student independence.
