Integrating HiPPO-Initialized SSM Subsystems into LLM Architectures

By utilizing HiPPO-initialized SSM side-car modules, engineers can theoretically achieve O(1) state inference latency and persistent memory, albeit at the cost of significantly increased integration complexity compared to traditional Transformer-only architectures.

Qwen2-VL GPTQ and AWQ benchmarks: what quantization does to multimodal accuracy

On Qwen2-VL-2B-Instruct, GPTQ-Int4 preserves most multimodal quality but still shows measurable drops versus BF16 on harder vision-language tasks — for example, MMMU falls from 41.88 to 39.22 and MathVista from 44.40 to 41.69 — while DocVQA stays comparatively stable, implying task sensitivity matters more than the bit-width label alone.

Agentic RAG with knowledge graphs: how multi-hop retrieval works under the hood

Knowledge-graph agentic RAG works by using entity links and graph traversal to expand the evidence frontier beyond nearest-neighbor chunk retrieval — this improves multi-hop recall when relationships matter — but it depends on strong entity resolution and graph quality, so noisy extraction can amplify wrong paths rather than fix them.

Neural Compression: A Framework for Joint Distillation and Quantization

Jointly applying Knowledge Distillation during Quantization-Aware Training (QAT) reduces the 'accuracy floor' typical of ultra-low bit-width models by transferring the inductive biases of the teacher model directly into the quantized weight space of the student, mitigating the signal loss inherent in post-training quantization.
