Uncertainty Makes It Stable: Curiosity-Driven Quantized Mixture-of-Experts
Read the original on arXiv AI →The paper introduces a curiosity‑driven quantized Mixture‑of‑Experts framework that routes inputs based on Bayesian epistemic uncertainty across heterogeneous experts (BitNet ternary, 1‑16 bit BitLinear, post‑training quantization). On audio classification benchmarks, 4‑bit quantization preserves 99.9 % of full‑precision F1 while achieving 4× compression and 31 % energy savings, and curiosity‑driven routing further improves accuracy and reduces cross‑fold variance by up to 85 %. The routing is self‑organizing, allocating the most uncertain samples to the high‑precision expert, and the method demonstrates statistical parity with full precision across datasets.
