Lecture Notes on Linear Neural Networks: A Tale of Optimization and Generalization in Deep Learning
This work provides foundational insights for researchers in machine learning, though it is incremental as it builds on existing mathematical frameworks.
The authors tackled the problem of understanding optimization and generalization in deep learning by developing a theory for linear neural networks, using dynamical mathematical tools to advance theoretical insights.
These notes are based on a lecture delivered by NC on March 2021, as part of an advanced course in Princeton University on the mathematical understanding of deep learning. They present a theory (developed by NC, NR and collaborators) of linear neural networks -- a fundamental model in the study of optimization and generalization in deep learning. Practical applications born from the presented theory are also discussed. The theory is based on mathematical tools that are dynamical in nature. It showcases the potential of such tools to push the envelope of our understanding of optimization and generalization in deep learning. The text assumes familiarity with the basics of statistical learning theory. Exercises (without solutions) are included.
