New Metric Inverted Sample Index (misi) for Efficient ANN Search

Researchers have developed a new data structure called misi, a Metric Inverted Sample Index, designed for efficient approximate nearest-neighbor search in metric spaces. This index uses a random sample of the database as its vocabulary, representing each object by its nearest sample points. The construction process is highly parallelizable and memory-efficient, making it suitable for frequently rebuilt corpora and batch similarity workloads where construction cost and memory footprint are critical.

    misi: a Metric Inverted Sample Index

    We present misi, an inverted index for approximate nearest-neighbor search over general metric spaces whose vocabulary is a random sample of the database, of size proportional to $n$. Each object is represented by its $k_b$ nearest sample points, found by a pluggable inner index …
