Joint or Per-Option? Compact Encoders for Closed-Set Decisions from 17 Million to 1 Billion Parameters

Many language-model pipelines end in a closed-set decision, such as selecting a tool. Prompting a large language model for it is slow and order-sensitive. We ask how small an encoder for such decisions can be and whether it should read the options jointly or separately. In a three-seed study at 32 million parameters, p...

ReDence: A Hybrid Agentic and Decision-Model Framework for Rapid, Evidence-Grounded Detection of Modern Social Engineering Scams

ReDence is presented, an open-source hybrid framework for adaptive, evidence-grounded detection across diverse SE scam categories, and achieves 96\% accuracy, substantially outperforming existing detectors while being at least four times faster than comparable agentic models without compromising investigative depth.

Random Projections for Spectral Algorithms: Optimal Rates in Sobolev Norms

Random projections (RP) offer an effective method for reducing computational and storage overhead while preserving the geometric structure of data. However, existing studies have primarily focused on the optimal generalization performance of specific kernel-regularized algorithms with RP in the well-specified setting a...

GateFormer: Forecast-Space Decomposition for Intra-Hour Solar Irradiance Prediction from Sky Images

Sub-hourly dispatch, balancing, and storage control increasingly depend on forecasts that anticipate rapid variability in solar generation. Accurate sky-image-based irradiance forecasting requires a combination of visual cloud dynamics with recent irradiance state while adapting to different short-term irradiance-chang...

PAIR: Preference-Aligned Intent Retrieval for Premium People Recommendation at LinkedIn

General-purpose embeddings trained on profile similarity often misrank candidates in professional networks, where relevance is inherently complementary rather than symmetric. For example, job seekers usually engage with recruiters rather than peers with similar credentials. Current user recommendation systems are often...

Vision Transformers for Estimating Irradiance Using Data Scarce Sky Images

Accurate estimation of diffuse horizontal irradiance (DHI) is critical for optimising photovoltaic system performance and energy forecasting yet remains challenging in regions lacking comprehensive ground-based instrumentation. Recent advancements using Vision Transformers (ViTs) trained on extensive sky image datasets...

Bridging Number-Theoretic Primality Testing And Algorithmic Optimization: An Adaptive Cryptographic Framework

The paper delineates an adaptive, arbitrary-precision architecture dedicated exclusively to primality testing, and deeply analyzes the theoretical foundations of testing methods, hardware-level optimization techniques, and the application of quantum-secured entropy sources, while providing rigorous mathematical proofs...

MIG-COW: Transferable Adversarial Attacks on Deepfake Detectors via Gradient Decomposition

MIG-COW is proposed, a novel adversarial attack framework that generates highly generalizable and visually imperceptible adversarial examples that captures both shared and model-specific vulnerabilities across heterogeneous CNN and ViT detectors.

Parameter Learning in Active Inference via Variational Message Passing

Active inference casts perception, learning and planning as variational inference, where the Expected Free Energy (EFE) defines the planning objective. Recent work showed that EFE minimization can be written as Variational Free Energy (VFE) minimization on a generative model augmented with epistemic priors, and that th...

Equilibria and Learning in Competitive Market Making

We propose a market-making game played among $N \ge 2$ strategic market makers and a single non-strategic representative trader. In a continuous quote space, standard finite-game arguments do not apply, while non-convex and discontinuous payoffs rule out classical continuous existence results and complicate learning. N...

Continuous-depth Deep Gaussian Processes

Deep Gaussian processes (DGPs) are appealing Bayesian regression models, but their standard discrete-depth parameterization often becomes harder to optimize as depth grows. We argue that depth is better treated as a latent continuous evolution than as a long discrete stack. We therefore propose a continuous-depth formu...

Semi-Linear Gaussian Bayesian Networks: Enhancing Flexibility in Node Dependencies via penalized B-Splines

The results show that, in the presence of nonlinear Gaussian relationships, SLGBN achieves better fit and improved structure recovery compared to alternative models, particularly when combined with the Extended Bayesian Information Criterion (EBIC*) score.
