Asking the Right Questions: AI’s Confidence Problem

23.12.2025 by qfx

The study demonstrates a probabilistic approach to question answering, where posterior predictive distributions-characterized by mean values and $ \pm 1\sigma $ uncertainty-effectively represent the model’s confidence in its predictions, with the predicted class indicated by a blue dot and the true label confirmed by a red star.

New research explores how quantifying uncertainty in neural networks can build more reliable and ethically sound question-answering systems.

The model delineates a procedure for analyzing single-event networks, defining intensity functions distinguished by source $𝐰_u$ and target $𝐳_v$ node embeddings, coupled with source $β_u$ and target $α_v$ random effects parameterized to represent node mass through an exponential function, and ultimately characterizing temporal impact via a function $f_v(t)$ that governs mass dynamics as $\exp{(\alpha_v)}f_v(t)$.

New machine learning techniques are unlocking deeper insights into the structure and dynamics of complex networks, from social systems to biological pathways.
