However, the main bottleneck of PC Networks (PCN) is the sequential backwards error propagation. To tackle this, we introduce a[training](/glossary/training)technique that pairs a Generative PCN with a support Encoding PCN. The two PCNs are trained in parallel to match their neural activations, without sequential propagation. We apply this to time series anomaly detection and show that our approach results in more stable, continuous, online learning.Get AI news in your inbox\n\nDaily digest of what matters in AI.", "url": "https://wpnews.pro/news/single-state-update-predictive-coding-training-for-time-series-forecasting-and", "canonical_source": "https://www.machinebrief.com/news/single-state-update-predictive-coding-training-for-time-seri-hi3f", "published_at": "2026-08-26 04:00:00+00:00", "updated_at": "2026-08-26 04:43:55.441638+00:00", "lang": "en", "topics": ["machine-learning", "artificial-intelligence"], "entities": ["Matteo Cardoni", "Sam Leroux", "Predictive Coding Networks"], "alternates": {"html": "https://wpnews.pro/news/single-state-update-predictive-coding-training-for-time-series-forecasting-and", "markdown": "https://wpnews.pro/news/single-state-update-predictive-coding-training-for-time-series-forecasting-and.md", "text": "https://wpnews.pro/news/single-state-update-predictive-coding-training-for-time-series-forecasting-and.txt", "jsonld": "https://wpnews.pro/news/single-state-update-predictive-coding-training-for-time-series-forecasting-and.jsonld"}}
