Overview of Nearest Neighbor Search Algorithms

The article reviews how high‑dimensional vector representations in deep‑learning applications require efficient approximate nearest‑neighbor search, comparing K‑d trees, hierarchical k‑means trees, locality‑sensitive hashing, product quantization, and HNSW graphs, and discusses practical FAISS implementations and how algorithm choice depends on data size, recall, latency, and resources.

Image Resizing Techniques on Android: Nearest‑Neighbour, Bilinear, Bicubic, and Lanczos Resampling

The article explains Android image downsampling, comparing built‑in nearest‑neighbour and bilinear methods with higher‑quality bicubic and Lanczos resampling, detailing their implementation, performance trade‑offs, and visual results, and advises choosing the fastest method for simple cases or the more intensive algorithms when superior image fidelity is required.
