Episode notes
Data Dependence of Deep Learning
- Deep learning's biggest limitation is its reliance on vast amounts of data, especially labeled data.
- Improving generalization ability and reducing data dependence are crucial for advancing the technology.
Deep Learning as Programs
- Deep learning models can be viewed as programs with sequential steps, not just singular representations.
- ResNets, for example, refine representations iteratively rather than replacing them at each layer.
Evolving Perspective on Adversarial Examples
- Adversarial examples initially highlighted a significant difference between machine learning and human perception.
- Now, they are viewed more as a security vulnerability than a fundamental flaw in machine learning.
