Optimizing for Multiple Objectives in Search and Recommendations (shaped.ai)
Building effective recommendation and search systems means going beyond simply predicting relevance. Modern users expect personalized experiences that cater to a wide range of needs and preferences, and businesses need systems that align with their overarching goals. This requires optimizing for multiple objectives simultaneously – a complex challenge that demands a nuanced approach. This post explores the concept of value modeling and multi-objective optimization (MOO), explaining how these techniques enable the development of more sophisticated and valuable recommendation and search experiences.

(Ab)using general search algorithms on dynamic optimization problems (2023) (dubovik.eu)
In retrospect, my most ambitious blog yet. As it goes, I was reading “Artificial Intelligence. A Modern Approach” the other day. In one of the earlier chapters the authors discuss general search algorithms: breadth-first search, depth-first search, uniform-cost search (Dijkstra), and variations of those. A bit later they also cover Monte Carlo tree search as a way of finding approximate solutions in big state spaces.

Using the most unhinged AVX-512 instruction to make fastest phrase search algo (gab-menezes.github.io)
Do you know when you go to your favorite search engine and search for something using double quotes, like a passage of a book/article or something very specific? That’s called phrase search (sometimes exact search). What we are telling the search engine is that we want these exact words in this exact order (this varies from search engine to search engine, but that’s the main idea).

Making the fastest phrase search algo with the most unhinged AVX512 instruction (gab-menezes.github.io)
For those who don’t want to read/don’t care that much, here are the results. I hope after seeing them you are compelled to read. TL;DR: I wrote a super fast phrase search algorithm using AVX-512 and achieved wins up to 1600x the performance of Meilisearch.
