A systematic workflow transforms raw data into categorized sentiment-specifically, classifications of Outrage, Hope, and Despair-through stages of collection, labeling, augmentation, and preprocessing prior to final classification.

A new analysis of social media data reveals the emotional landscape of Bangladesh’s recent mass uprising, offering insights into public sentiment during a period of intense political and social change.

The Strength of Many: How Diverse AI Models Avoid Knowledge Loss

18.12.2025 by qfx

$AI ecosystems, constrained by inherent biases and finite data, inevitably succumb to a process of informational collapse, where repeated training and generation cycles narrow the probability distribution of knowledge - represented as $p_{\theta}$ - toward meaningless homogeneity, a degradation occurring both within individual models and across entire collectives, and ultimately diverging from the expected growth of human knowledge, represented by the original data distribution $p_{data}$.$

New research reveals that a healthy degree of variation among artificial intelligence models is key to preventing performance degradation and maintaining robust knowledge over time.
