Beyond Linearity: A New Architecture for Accurate Time Series Forecasting

29.01.2026 by qfx

ACFormer establishes a framework where shared patch compression distills information before temporal gated attention refines it, ultimately enabling independent patch expansion - a process suggesting the system doesn’t simply process data, but actively deconstructs and reconstructs it to reveal underlying patterns.

Researchers have developed ACFormer, a novel approach that blends convolutional efficiency with the power of attention mechanisms to dramatically improve time series prediction.

The Illusion of Explanation in Graph Neural Networks

29.01.2026 by qfx

Explanation-guided graph neural networks, despite achieving accurate predictions, are susceptible to generating ‘degenerate’ explanations - outputs that correctly encode the predicted label by exploiting irrelevant, consistently-colored nodes - effectively misleading users into believing these nodes drive the model’s inference when they do not, a phenomenon demonstrated by the network’s ability to utilize an ‘anchor set’ [latex]\mathcal{Z}[/latex] of class-indiscriminative nodes to secretly encode predictions.

Despite achieving high accuracy, many self-explainable graph neural networks offer explanations that don’t reflect how they actually make decisions, raising concerns about their trustworthiness.

The Whale in the Room: How Big Money Distorts Prediction Markets

29.01.2026 by qfx

The simulation demonstrates that market valuations, even when driven by as few as 100 agents over 100 time steps, consistently reflect underlying election outcomes, though predictive accuracy is predictably degraded by individual biases, risk aversion, and the inherent noise within both the market price and the true result-particularly around a 0.5 probability, where misclassification risk increases and confidence in alignment between prediction and reality diminishes, as evidenced by the widening transition zone between correct and incorrect classifications with increased uncertainty, despite parameter variations tested across expertise, stubbornness, and budget constraints [latex] B\_{i,0}\sim U(100,1000), V\_{i,0}\sim N(0.5,0.05), s\_{i}\sim\mathcal{N}(0.3,0.05), e\_{i}\sim\mathcal{N}(0.9,0.04), r\_{i}\sim U(0,1) [/latex].

New research reveals that even generally reliable prediction markets are vulnerable to price manipulation by large, well-funded participants, especially when combined with investor herd mentality.

Beyond Bias: Ensuring Fairness for All Machine Learning Outcomes

29.01.2026 by qfx

The study demonstrates that identifying subgroups experiencing the greatest unfairness-particularly within conjunction subgroups [latex]\mathcal{S}_A[/latex] as a subset of broader linear subgroups [latex]\mathcal{S}_L[/latex]-yields optimal solutions, as evidenced by the performance of MSD and GerryFair relative to alternative approaches.

New research tackles the complex challenge of intersectional bias in machine learning models, offering a robust framework for fairer and more equitable results.
