    Intuition question. You draw two vectors from an n-dimensional isotropic Gaussian where n>>1. What is the typical angle between them?

    Wealth is the power to choose. Financial wealth is the power to choose how to spend money. Social wealth is the power to choose who to hang out with. Calendar wealth is the power to choose how to spend your time. Mental wealth is the power to choose your thoughts.

    I realized recently that we were late in sharing data from a published paper. Mea culpa!! We have now assembled the data (~500K decisions from 29 mice) & made it available: . Paper is this:

    A secret for discovering really great things: look for things that are said to have a "cult" following. Sometimes this is literally true, but other times it's because the thing is genuinely great, but not everyone knows yet.

    When making plans, think big. When making progress, think small.

    These would be road tunnels for zero emissions vehicles only — no toxic fumes is the key. Really, just an underground road, but limited to EVs (from all auto companies). This is not in place of other solutions, eg light rail, but supplemental to them.

    I am increasingly bothered by a question I keep encountering regarding China’s repression of the Uighurs: “Why aren’t Muslim-majority countries condemning it?” There are several things that bother me about this question.

    Reformer: The Efficient Transformer They present techniques to reduce the time and memory complexity of Transformer, allowing batches of very long sequences (64K) to fit on one GPU. Should pave way for Transformer to be really impactful beyond NLP domain

    I think we tend to overestimate the importance of reciprocity -- a transactional mindset -- and underestimate the power of kindness. Even the smallest acts of kindness can change lives. None of the most important things in life are transactional.

    Generalisation is about the simplicity of the model class that is compatible with all observed and experimental(interventional) data. Simplicity doesn't mean a small number of parameters. It means that we need a small number of bits to describe the model 2/5

    is one of the few intellectuals driven towards mending the political and social divides within society. I respect that he is willing to engage those he disagrees with while maintaining civility in times of conflict.

    Bayesian methods are *especially* compelling for deep neural networks. The key distinguishing property of a Bayesian approach is marginalization instead of optimization, not the prior, or Bayes rule. This difference will be greatest for underspecified models like DNNs. 1/18

    Rephrasing with my own words: DL is a collection of tools to build complex modular differentiable functions. These tools are devoid of meaning, it is pointless to discuss what DL can or cannot do. What gives meaning to it is how it is trained and how the data is fed to it
