Researchers introduce GS-Fuse, a machine learning framework that improves financial forecasting by intelligently combining event-driven text with price data. The system uses causal analysis to determine when news actually predicts market movements, addressing a key limitation in existing multimodal AI models that treat all data sources equally.
Researchers introduce DA-GC, a certified causal attribution framework for detecting cross-slice attacks in 6G networks within strict 100ms latency constraints. The system combines resource-conditioned Granger causality with a formal Resource Contention Model to distinguish genuine attack propagation from spurious correlations caused by shared infrastructure, achieving 89.2% accuracy with mathematical proof of statistical validity.
Researchers rigorously tested claims that Mamba state-space models can discover causal structure through prediction-only training, finding the method underperforms classical approaches like PCMCI and Granger causality. The apparent success in earlier experiments was largely attributable to sample-size confounds and non-standard intervention semantics rather than genuine architectural advantages.
