Jun 12, 2022 Counting Consciousnesses
Is it possible that a brain has multiple consciousnesses? What are the moral implications?.
Nov 20, 2021 About Energy-Based Models
I present the formulation of deep energy-based models.
Sep 8, 2021 About Variational Autoencoders
I present the formulation of variational autoencoders.
Feb 10, 2021 A Note on the Dimension of Random Vectors in End-to-End Differentiable Systems
A short argument showing that when optimizing a stochastic differentiable system with SGD, the source of randomness should be of as small a dimension possible.
Jan 9, 2021 Visualizing Policies of Soft Actor Critic
I show some visualizations of the non-deterministic optimal policies of the SAC reinforcement learning algorithm.
Feb 7, 2020 A Fresh Perspective of the Bias-Variance Tradeoff
I show how to talk about bias and variance of data (instead of model)
Nov 8, 2019 Nostalgia Post
Following the first post of the blog, I mention some other things that I did as a teenager, and I'm somewhat proud of.
Nov 8, 2019 Learning Quantum Dynamics with Feynman's Path Integrals
Through the lens of a deep learning practitioner, the elegant path integral formulation of quantum mechanics looks like a an expectation over trajectories of a reinforcement learning agent.
Oct 25, 2019 A New Generative Model?
Initial thoughts about a new formalism for generative models.
Oct 14, 2019 My Failed Attempt to Crack RSA
I describe a hypothetical machine that I came up with years ago, which I thought could help crack RSA (I was very wrong). The machine is based on electric charges moving in a magnetic field.
