LangWatch Open Sources a Virtual Testing Framework for AI Agents to Enable End-to-End Tracking, Simulation, and Systematic Testing

LangWatch Open Sources a Virtual Testing Framework for AI Agents to Enable End-to-End Tracking, Simulation, and Systematic Testing

As AI development shifts from simple conversational interfaces to autonomous, multi-step agents, the industry has encountered a critical bottleneck: not deciding. Unlike conventional software where code follows a predictable path, agents built into LLMs introduce a high level of variability. LangWatch is an open source platform designed to address this by providing a standardized layer … Read more

Time Series Cross Validation: Techniques and Applications

Time Series Cross Validation: Techniques and Applications

Time series data drives forecasting in finance, sales, healthcare, and energy. Unlike typical machine learning problems, it must preserve chronological order. Ignoring this property leads to data leakage and misleading performance estimates, making model testing unreliable. Cross-validation of time series addresses this by maintaining temporal integrity during training and testing. In this article, we cover … Read more

Physical Intelligence Team Unveils MEM for Robots: A Multiscale Memory System That Gives Gemma 3-4B VLAs 15-Minute Context for Complex Tasks

Physical Intelligence Team Unveils MEM for Robots: A Multiscale Memory System That Gives Gemma 3-4B VLAs 15-Minute Context for Complex Tasks

Current robotics policies, especially Vision-Language-Action (VLA) models, often work with a single observation or a very short history. This ‘memory deficit’ makes long-horizon tasks, such as cleaning the kitchen or following a complex recipe, impossible to compute or prone to failure. To address this, researchers from Physical Intelligence, Stanford, UC Berkeley, and MIT have presented … Read more

Meet SymTorch: A PyTorch Library That Translates Deep Learning Models into Human-Readable Statistics

Meet SymTorch: A PyTorch Library That Translates Deep Learning Models into Human-Readable Statistics

Could symbolic regression be the key to turning fuzzy deep learning models into interpretive, closed-loop statistics? or Say you trained your deep learning model. It works. But do you know what it actually reads? A team of researchers from the University of Cambridge proposes ‘SymTorch’, a library designed to integrate symbolic reduction (SR) in the … Read more

How to Build a Stable and Efficient QLoRA Tuning Pipeline Using Unsloth for Large Language Models

How to Build a Stable and Efficient QLoRA Tuning Pipeline Using Unsloth for Large Language Models

In this tutorial, we show how to fine-tune a macro language model using Misbehavior and QLoRA. We focus on building a stable, well-maintained pipeline that handles common Colab problems such as GPU detection failures, runtime crashes, and library incompatibilities. By carefully controlling the environment, model configuration, and training loop, we demonstrate how to reliably train … Read more
