Tensor programming for databases, with first class dimensions

Tensor libraries like PyTorch and JAX have developed compact and accelerated APIs for manipulating n-dimensional arrays. N-dimensional arrays are kind of similar to tables in database, and this results in the logical question which is could you setup a Tensor-like API to do queries on databases that would be normally done with SQL? We have […]

What’s different this time? LLM edition

One of the things that I learned in grad school is that even if you've picked an important and unsolved problem, you need some reason to believe it is solvable--especially if people have tried to solve it before! In other words, "What's different this time?" This is perhaps a dreary way of shooting down otherwise […]
