Uncovering Hidden Signals in Finance with AI

25.11.2025 by qfx

CogAlpha cultivates investment strategies through a seven-level agent hierarchy that distills initial alphas from OHLCV data, subsequently subjecting each candidate to rigorous quality assessment and predictive power evaluation-using five distinct metrics-before iteratively refining and recombining qualified strategies via deeper reasoning facilitated by large language models.

A new approach combines the power of large language models and evolutionary algorithms to identify more reliable and understandable investment strategies.

Predicting What You’ll Do Next on Social Media

25.11.2025 by qfx

A database analysis of 10,000 messages revealed a concentrated region of highly influential content-messages garnering over ten votes where a single action consistently dominated with a winner percentage exceeding 90% across all identified clusters-suggesting a predictable pattern of consensus within the system.

A new approach accurately forecasts user behavior, from everyday actions to the surprisingly rare, on platforms like Bluesky.

When Machine Learning Models Reveal Your Secrets

25.11.2025 by qfx

The study demonstrates that as a DenseNet model trains on CIFAR10, overfitting distorts the distribution of scaled logits for both training data and genuinely out-of-distribution samples, directly impacting accuracy and rendering standard Membership Inference Attacks (MIA) increasingly unreliable as a means of determining if a data point contributed to model training.

New research demonstrates that even well-trained machine learning models can be vulnerable to attacks that reveal whether specific data points were used in their training.

Graph Networks Spot Network Threats with Speed and Precision

24.11.2025 by qfx

AutoGraphAD establishes a training pipeline centered on reconstructing graph structures and features from latent embeddings-generated by a flexible GNN encoder-and leveraging the resulting reconstruction loss for back-propagation, allowing for modularity in both the GNN architecture and the loss functions employed, effectively treating the system as an evolving ecosystem rather than a fixed mechanism.

A new unsupervised learning approach leverages the power of graph autoencoders to detect anomalous network traffic with significantly improved performance.
