Fashion Shopping with Nearest Neighbors
I made this website with my wife in mind; it makes it possible to browse for similar fashion products over many different retailers at once. The backend is written in Swift, and is hosted on a single Mac Mini. It performs nearest neighbors on the GPU over ~3M product images. No vector DB, just pure matrix multiplications. Since we aren't just doing approximate nearest neighbors but rather sorting all results by distance, it's possible to show different "variety" levels by changing the stride over the sorted search results. Nearest neighbors are computed in a latent vector space. The model…
Fashion Shopping with Nearest Neighbors launched on March 15, 2025 with 76 votes, #466 of 7,215 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Fashion Shopping with Nearest Neighbors lets users browse similar clothing items across multiple retailers simultaneously. The tool uses GPU-accelerated nearest neighbor search across approximately 3 million product images to find visually similar fashion pieces. Built with Swift and running on a Mac Mini, it searches a latent vector space and allows users to adjust result variety by changing the stride through sorted matches. The backend uses pure matrix multiplications without a vector database, and the underlying model was trained entirely in Swift.

Vicinity – Fast, Lightweight Nearest Neighbors with Flexible Back Ends2024 · github.com · ▲57We’ve just open-sourced Vicinity, a lightweight approximate nearest neighbors (ANN) search package that allows for fast experimentation and comparison of a larger number of well known algorithms. Main features: - Lightweight: the base package only uses Numpy - Unified interface: use any of the supported algorithms and backends with a single interface: HNSW, Annoy, FAISS, and many more algorithms and libraries are supported - Easy evaluation: evaluate the performance of your backend with a simple function to measure queries per second vs recall - Serialization: save and load your index for…
SnapMeasureAI2025 · snapmeasureai.com · ▲98I built a tool to reduce shopping returns. The tool provides accurate body measurements from images or video. By providing accurate measurements, customers will have confidence while shopping. The demo is free, so give it a try. All thoughts and feedback are appreciated.
Fast vector similarity using Rust and Python2023 · github.com · ▲141I recently found myself computing the similarity between lots of very high dimensional vectors (i.e., sentence embedding vectors from LLMs), and I wanted to try some more powerful measures of similarity/dependency than just Cosine similarity, which seems to be the default for everything nowadays because of its computational efficiency. There are many other more involved measures that can detect more subtle relationships, but the problem is that some of them are quite slow to compute, especially if you're trying to do it in Python. For my favorite measure of statistical dependency,…
- AGA GPU-accelerated binary vector index2025 · rlafuente.com · ▲65
This is a vector index I built that supports insertion and k-nearest neighbors (k-NN) querying, optimized for GPUs. It operates entirely in CUDA and can process queries on half a billion vectors in under 200 milliseconds. The codebase is structured as a standalone library with an HTTP API for remote access. It’s intended for high-performance search tasks—think similarity search, AI model retrieval, or reinforcement learning replay buffers. The codebase is located at https://github.com/rodlaf/BinaryGPUIndex.
