Langevin Sampling and Score Matching
We often treat the 'normalization constant' in deep learning as a mathematical headache. But by looking at it through the lens of physics, we find a solution. This post breaks down how Langevin dynamics allows us to bypass the intractable integral and generate data using the 'score function'—physics' answer to generative modeling.
