Fast search index for SPLADE sparse retrieval models implemented in Python using Numpy and Numba

Lite weight wrapper for the independent implementation of SPLADE++ models for search & retrieval pipelines. Models and Library created by Prithivi Da, For PRs and Collaboration checkout the readme.

Provides a minimal PyTorch implementation of SPLADE

🚀 Engram-PEFT: An unofficial implementation of DeepSeek Engram. Inject high-capacity conditional memory into LLMs via sparse retrieval PEFT without increasing inference FLOPs / DeepSeek Engram 架构的非官方实现。通过参数高效微调 (PEFT) 为大语言模型注入超大规模条件记忆，支持稀疏更新且不增加推理开销。

SPLADE (Sparse Lexical AnD Expansion) model fine-tuned for Portuguese text retrieval. Based on BERTimbau and trained on Portuguese question-answering datasets.

Python code to train SPLADE sparse retrieval models based on BERT-Tiny (4M) and BERT-Mini (11M) by distilling a Cross-Encoder on the MSMARCO dataset

Demo for SenTrEv python package

A personal knowledge base that ingests PDFs and markdown notes, then answers questions using a hybrid search system combining dense vector search and BM25 with a side by side dashboard showing how each retrieval method performs on any given query.

Semantic Hybrid Search with Sentence-Transformers + FAISS. Ask any question in plain English. Get the most relevant Wikipedia passages back — ranked by meaning, not just keywords.

A controlled experiment evaluating whether hybrid (dense + sparse) retrieval surfaces evidence that dense-only RAG systems misrank—without changing generation behavior.
