Quantization-Triggered Backdoors in Language Models: Cross-Quantizer Transferability and the Validation--Deployment Gap 🔬 arXiv cs.LG (Machine Learning) · Score: 9/10 Post-training quantization, commonly used for edge deployment, can be weaponized to introduce hidden backdoors in LLMs that transfer across different quantization methods. This reveals a validation-deployment gap that practitioners must address before quantizing models for production. Read more → 🔥 2. DAMP: Decay-Aware Mixed-Precision Recurrent-State Quantization 🔬 arXiv cs.LG (Machine Learning) · Score: 9/10 DAMP addresses the quadratic memory scaling of attention by introducing decay-aware mixed-precision quantization for key-value caches. This enables longer sequence lengths and faster inference on resource-constrained devices, directly improving real-world deployment. Read more → ⭐ 3. VICT: Verifier-Instrumented Credit Tracing for Long-Horizon LLM Agent Reinforcement Learning 🔬 arXiv cs.LG (Machine Learning) · Score: 8/10 VICT solves fine-grained credit assignment for long-horizon LLM agent tasks by using verifier
