You don’t walk up stairs in real-time. If you did, you’d be slow—each step requiring conscious processing of elevation, texture, muscle tension, and balance. Instead, your brain generates a high-resolution prediction of the next stair before your foot lands.1 You only become conscious of it when the simulation fails. When your foot hits floor sooner than expected. Or when you find empty air where a step should be. It’s a prediction error that jolts you back to consciousness […]

While graph-derived signals are widely used in tabular learning, existing studies typically rely on limited experimental setups and average performance comparisons, leaving the statistical reliability and robustness of observed gains largely unexplored. Consequently, it remains unclear which signals provide consistent and robust improvements. This paper presents a taxonomy-driven empirical analysis of graph-derived signals for tabular machine learning. We propose a unified and reproducible evaluation protocol to systematically assess which categories of graph-derived signals yield statistically significant and robust […]

In offline reinforcement learning (RL), single-step temporal-difference (TD) learning can suffer from bootstrapping error accumulation over long horizons. Action-chunked TD methods mitigate this by backing up over multiple steps, but can introduce suboptimality by restricting the policy class to open-loop action sequences. To resolve this trade-off, we present Chunk-Guided Q-Learning (CGQ), a single-step TD algorithm that guides a fine-grained single-step critic by regularizing it toward a chunk-based critic trained using temporally extended backups. This reduces compounding error while […]

In High Energy Physics, as in many other fields of science, the application of machine learning techniques has been crucial in advancing our understanding of fundamental phenomena. Increasingly, deep learning models are applied to analyze both simulated and experimental data. In most experiments, a rigorous regime of testing for physically motivated systematic uncertainties is in place. The numerical evaluation of these tests for differences between the data on the one side and simulations on the other side quantifies […]

In the dim glow of the maintenance bay on Nimbus Station, a floating outpost tucked among the jagged rocks of the asteroid belt, Zev wiped the grease from his hands and stared at the battered frame before him. Nimbus wasn’t much more than a cluster of pressurized domes and spinning habitats, home to a few thousand souls scratching out a living from mineral hauls and repair jobs. The place had that gritty feel of a frontier town, where […]

Hello World is a weekly newsletter—delivered every Saturday morning—that goes deep into our original reporting and the questions we put to big thinkers in the field. Browse the archive here. Hi, everyone — Colin Lecher here, an investigative reporter at The Markup. Back in March, we broke some news about a small-business advice chatbot being piloted by the New York City government. The bot — available at chat.nyc.gov — was meant to be an AI-powered, one-stop shop for entrepreneurs […]

Predicting satellite imagery requires a balance between structural accuracy and textural detail. Standard deterministic methods like PredRNN or SimVP minimize pixel-based errors but suffer from the "regression to the mean" problem, producing blurry outputs that obscure subtle geographic-spatial features. Generative models provide realistic textures but often misleadingly reveal structural anomalies. To bridge this gap, we introduce Sat-JEPA-Diff, which combines Self-Supervised Learning (SSL) with Hidden Diffusion Models (LDM). An IJEPA module predicts stable semantic representations, which then route a […]

Reconciliation at scale is the difference between trusting your financial records and spending nights chasing mismatches across multiple parties. At Lead Bank, we build the infrastructure that collects, processes, and reconciles data for card and deposit programs to support correctness, auditability, and compliance obligations. Reconciliation verifies consistency across the bank core, card network files, issuing processor reports, and fintech program data. Because it spans multiple parties, the workflow is inherently multi-legged, and a single mismatch can trigger costly […]

Many machine learning classification tasks involve imbalanced datasets, which are often subject to over-sampling techniques aimed at improving model performance. However, these techniques are prone to generating unrealistic or infeasible samples. Furthermore, they often function as black boxes, lacking interpretability in their procedures. This opacity makes it difficult to track their effectiveness and provide necessary adjustments, and they may ultimately fail to yield significant performance improvements. To bridge this gap, we introduce the Decision Predicate Graphs for Data […]
