The post discusses the process of multiplying polynomials and the relationship to convolution sums. It begins with the traditional method of cross-multiplying polynomials and collecting terms, then introduces a more systematic approach using a table to visualize how coefficients correspond to specific terms in the output. The table highlights the necessary diagonals that combine to form each term's coefficient. The text then shifts to an abstract representation of polynomials as sums of coefficients multiplied by powers of x. When two polynomials, P and R

Hashing is a principle that may seem complex but is fundamentally straightforward. It involves a one-way function that takes any type of input—such as strings, numbers, or files—and produces a fixed-size output, typically in binary format. The output size remains constant regardless of the input size. For example, a hash of the string "hello" could generate a 4-bit output, illustrating how diverse data can be transformed into a uniform size through hashing algorithms. Although hashing has many intricacies, its

The author, along with Chris, created a blog search engine using word embeddings, specifically employing the word2vec method, which maps words onto a 300-dimensional space that reflects their meanings. They followed a blog post detailing how to train a mini word2vec to understand its internals. The search engine works by embedding each blog post through the sums of the embeddings of its words and then embedding search queries similarly. Posts are ranked based on the cosine similarity of their embeddings to the search query, which
