BACH: A Bayesian Admixture of Contrastive Heads for Multi-Interest Two-Tower Retrieval

This feed aggregates recent research (July 10, 2026) on retrieval, generative retrieval, hashing, log forensics, multi-agent LLM systems, and code-completion security. Notable items with direct security or operational impact: (1) "Beware What You Autocomplete: Forensic Attribution of Backdoored Code Completions" (CodeTracer) presents a practical forensic method to trace malicious code-completion outputs back to poisoned fine‑tuning data — relevant to supply-chain and model poisoning defenses and attribution. (2) "Log-Insight" describes a deployed, neuro-symbolic pipeline that compresses and pr
