Demonstration of simple retrieval technique based on cosine similarity

How to use

retieval.cpp has parameters of its own:

  • --context-file: file to be embedded - state this option multiple times to embed multiple files
  • --chunk-size: minimum size of each text chunk to be embedded
  • --chunk-separator: STRING to divide chunks by. newline by default

retrieval example can be tested as follows:

make -j && ./retrieval --model ./models/bge-base-en-v1.5-f16.gguf --top-k 3 --context-file README.md --context-file License --chunk-size 100 --chunk-separator .

This chunks and embeds all given files and starts a loop requesting query inputs:

Enter query:

On each query input, top k chunks are shown along with file name, chunk position within file and original text:

Enter query: describe the mit license
batch_decode: n_tokens = 6, n_seq = 1
