AlignCoder Uses Reinforcement Learning to Improve Repository-Level Code Completion by 18%

AlignCoder is a novel framework for repository-level code completion that combines query enhancement with reinforcement learning to train a retriever (AlignRetriever). It addresses misalignment issues in retrieval-augmented generation (RAG) approaches, achieving an 18.1% improvement in Exact Match score on the CrossCodeEval benchmark across multiple code LLMs.

Semantic Pyramid Indexing: Adaptive Query Depth for Streaming RAG in Vector Databases

Researchers propose Semantic Pyramid Indexing (SPI), a vector database indexing framework that adapts retrieval depth per query in streaming RAG pipelines. SPI organizes embeddings into semantic resolution levels, reducing average latency by 1.4–2.3× at fixed Recall@10 on standard benchmarks, and demonstrates 6.2× throughput scaling on 8 nodes. The framework supports incremental updates and is compatible with FAISS and Qdrant backends.
