Machine learning news — deep learning, reinforcement learning, neural architecture search, diffusion models, and new ML frameworks and libraries.
PyTorch's .backward() method performs a graph traversal that applies the chain rule node-by-node rather than deriving a global formula, according to a technical explainer. The article uses the example z = 2x^2 + 1 with x…
Anthropic published research on October 29, 2025 showing that Claude Opus 4.1 identified concepts injected into its neural activations in about 20% of trials under the best tested conditions, while production models prod…
A new analysis warns that standard AI alignment techniques such as Reinforcement Learning from Human Feedback (RLHF) create a 'compliance mirage,' leaving large language models vulnerable to latent trojans that can be ac…
Wired reports that consumer neurotechnology is advancing rapidly, with Apple, Meta, and Snap developing products that can monitor or interpret brain activity, prompting neuroscientists to call for 'neurorights' to protec…
A developer from Multigrid AI demonstrates that a first-order Markov chain over page types is the best starting point for predicting the next action in clickstream sequences. The model is simple to fit, interpretable, an…
A developer at Multigrid.ai explains how AI models predict chemical reaction outcomes, covering sequence-to-sequence models like the Molecular Transformer and graph-based reaction-centre prediction. The post details the …
A study published in iScience found that dogs' brains can distinguish between specific negative human facial expressions, not just positive versus negative emotions. Researchers at Eötvös Loránd University used fMRI scan…
Quarkslab has released pcode_graph, a Python library for building semantic graphs from binary code, and demonstrated its use in detecting function similarities across architectures and compilers using the Cisco-Talos dat…
Liftoff reported Q2 revenue of $220 million, up 35% year-over-year, and adjusted EBITDA of $132 million, up 55%, in its first earnings call as a public company. CEO Jeremy Bondy attributed the performance to its Cortex m…
Diffusion models have become one of the most influential families of generative AI systems, powering applications from image synthesis to video generation, according to a paper review published by freeCodeCamp. The revie…
Volkswagen is applying its platform strategy to autonomous driving with the HS8 platform, which includes the GAIA 2.0 data and simulation system and the HS foundation model, deployed in vehicles starting with the ID. ERA…
Audio tagging models, which classify multiple simultaneous sounds in a clip, differ fundamentally from single-label classifiers by using independent sigmoid outputs and binary cross-entropy instead of softmax. Google's Y…
An evaluation protocol for choosing audio embedding models for similarity search across a sound library is described. The protocol emphasizes that retrieval quality depends on the library's recording conditions and that …
A developer explains the inner workings of PyTorch's autograd engine, detailing how the .backward() method computes gradients by walking a computation graph in reverse. The post uses the example y = x² to illustrate that…
A developer's comparison of machine learning models for predicting IMDb scores found that Random Forest significantly outperformed Linear Regression, with a mean absolute error of 0.68 versus 1.42 and an R² score of 0.74…
Prime Intellect has open-sourced Prime Agent, a framework for building self-improving recursive language model (RLM) agents that operate in a persistent Python REPL. The framework enables agents to retain state, spawn su…
Roblox is hiring a Senior Machine Learning Engineering Manager for Text Safety in San Mateo, CA, offering a salary of $345k–399k/yr. The role involves leading a team to develop AI solutions for language and text content …
On July 1, 2026, developer JustVugg released Colibri, a 14,700-line pure-C inference engine that runs GLM-5.2, a 744-billion-parameter Mixture-of-Experts model, on 25GB of RAM with no GPU, using an LRU cache to load expe…
Applied Intuition, Inc., a $15 billion Silicon Valley company founded in 2017, is hiring a Software Engineer for Prediction and Planning ML in Sunnyvale, California, with a salary range of $151,000 to $258,000 per year. …
Applied Intuition, Inc., a $15 billion Silicon Valley company founded in 2017, is hiring a Machine Learning Performance Engineer for its Sunnyvale office with a salary of $215k–285k/yr. The role focuses on optimizing dis…
