Policy gradient algorithms have driven many recent advancements in language model reasoning. An appealing property is their ability to learn from exploration on their own trajectories, a process crucial for fostering diverse and creative solutions. As we show in this paper, many policy gradient algorithms naturally reduce the entropy — and thus the diversity of explored trajectories — as part of training, yielding a policy increasingly limited in its ability to explore. In this paper, we argue that […]

Constrained autoencoders (cAE) provide a successful path towards interpretable dimensionality reduction by enforcing geometric structure on latent spaces. However, standard cAEs cannot adapt to varying physical parameters or environmental conditions without conflating these contextual shifts with the primary input. To address this, we integrated a neuromodulatory mechanism into the cAE framework to allow for context-dependent manifold learning. This paper introduces the Neuromodulated Constrained Autoencoder (NcAE), which adaptively parameterizes geometric constraints via gain and bias tuning conditioned on static […]

This paper introduces a novel optimization framework that fundamentally integrates the Minimum Description Length (MDL) principle into the training dynamics of deep neural networks. Moving beyond its conventional role as a model selection criterion, we reformulate MDL as an active, adaptive driving force within the optimization process itself. The core of our method is a geometrically-grounded cognitive manifold whose evolution is governed by a textit{coupled Ricci flow}, enriched with a novel textit{MDL Drive} term derived from first principles.

Continual Reinforcement Learning (CRL) for Vision-Language-Action (VLA) models is a promising direction toward self-improving embodied agents that can adapt in openended, evolving environments. However, conventional wisdom from continual learning suggests that naive Sequential Fine-Tuning (Seq. FT) leads to catastrophic forgetting, necessitating complex CRL strategies. In this work, we take a step back and conduct a systematic study of CRL for large pretrained VLAs across three models and five challenging lifelong RL benchmarks. We find that, contrary to established […]

Every enterprise .NET application that processes documents will eventually need OCR (Optical Character Recognition). The wrong library choice costs months. The best OCR library for your needs can elevate your entire workflow. I spent six weeks evaluating 14 OCR libraries across the .NET ecosystem—open-source wrappers, commercial SDKs, and cloud APIs—running them against the same corpus of scanned invoices, handwritten forms, multilingual contracts, and degraded TIFFs. This is the comparison I wished existed when I started. Disclosure: This article […]

Coull Shruthi Mahalingaiah ::: Abstract Menstrual characteristics are important signs of women’s health. Here we examine the variation of menstrual cycle length by age, ethnicity, and body weight using 165,668 cycles from 12,608 participants in the US using mobile menstrual tracking apps. After adjusting for all covariates, […]

If you are choosing a C# barcode library for a .NET project right now, you are facing a harder decision than you might expect. The ecosystem has grown to include at least a dozen viable options, from zero-cost open-source packages to enterprise SDKs that cost thousands. Each makes compelling claims about format support, performance, and cross-platform compatibility. Very few of those claims are tested side by side, in one place, with honest tradeoffs laid bare. This matters because […]
