A Coding Guide Implementing SHAP Explainability Workflows with Explainer Comparisons, Maskers, Interactions, Drift, and Black-Box Models

In this tutorial, we implement SHAP workflows as a practical framework for interpreting machine learning models beyond basic feature-importance plots. We start by training tree-based models and then compare different SHAP explainers, including Tree, Exact, Permutation, and Kernel methods, to understand how accuracy and runtime change across model-aware and model-agnostic approaches. We also examine how […]

Nous Research Proposes Lighthouse Attention: A Training-Only Selection-Based Hierarchical Attention That Delivers 1.4–1.7× Pretraining Speedup at Long Context

Training large language models on long sequences has a well-known problem: attention is expensive. The scaled dot-product attention (SDPA) at the core of every transformer scales quadratically Θ(N²) in both compute and memory with sequence length N. FlashAttention addressed this through IO-aware tiling that avoids materializing the full N×N attention matrix in high-bandwidth memory, reducing

Canvas hack: is it ever a good idea to pay a ransom, and what happens to the data?

Businesses are advised against paying – but many are prepared to deal to protect users’ privacyAfter a week of outages, hundreds of millions of students’ data stolen, delayed assignment due dates and school login pages being defaced by hackers, the US tech firm Instructure – which operates the education platform Canvas, used by education providers

Meet LiteLLM Agent Platform: A Kubernetes-Based, Self-Hosted Infrastructure Layer for Isolated Agent Sandboxes and Persistent Session Management in Production

Running AI agents in a local script is straightforward. Running them reliably in production across teams, across restarts, with isolated environments per context is a different problem entirely. BerriAI, the company behind the LiteLLM AI Gateway, is now open-sourcing a purpose-built answer to that problem: the LiteLLM Agent Platform. The platform is described as a

John Lennon: The Last Interview review – Soderbergh imagines there’s no people with bland AI clipshow

Succession of pointless AI-generated snippets does nothing for film about the artist’s final interview, which took place on the day of his murderComing just after his superb feature The Christophers, Steven Soderbergh has now made a surprisingly moderate documentary, dominated and frankly marred by uninteresting and pointless AI. It is about the inadvertently poignant final

What we learned from the cringey courtroom drama between Elon Musk and Sam Altman

Two of the world’s richest people faced an airing of their dirty laundry amid their messy, bitter feud over OpenAIA nine-person jury is set to decide whether Elon Musk’s allegations of “stealing a charity” against Sam Altman and OpenAI are legitimate, with deliberations to begin in earnest on Monday. Whatever its outcome, the case has

Pity the poor AI data centers facing ‘discrimination’ | Arwa Mahdawi

The centers are diverting much-needed resources from regular people. Local resistance has the industry playing defenseBack in 2016, Marco Gutiérrez, the Mexican-born founder of Latinos for Trump, issued an ominous warning to the US. “My culture is a very dominant culture,” he said on MSNBC. “It is imposing and it’s causing problems. If you don’t

NVIDIA Introduces SANA-WM: A 2.6B-Parameter Open-Source World Model That Generates Minute-Scale 720p Video on a Single GPU

World models (systems that synthesize realistic video sequences from an initial image and a set of actions) are becoming central to embodied AI, simulation, and robotics research. The core challenge is scaling these systems to generate minute-long, high-resolution video without requiring prohibitively large clusters for both training and inference. Most competitive open-source baselines either require

Zyphra Releases ZAYA1-8B-Diffusion-Preview: The First MoE Diffusion Model Converted From an Autoregressive LLM With Up to 7.7x Speedup

Zyphra, the San Francisco-based AI lab behind the ZAYA1 model family, released ZAYA1-8B-Diffusion-Preview — a preview of its early work in diffusion-language models. The release demonstrates that an existing autoregressive language model can be converted into a discrete diffusion model with no systematic loss of evaluation performance, while delivering substantial inference speedups on AMD hardware.

Richard Dawkins and the question of AI consciousness | Letters

Salley Vickers and Carrie Eckersley respond to a letter on Richard Dawkins and his chats with AI botsI was delighted to read Dr Simon Nieder’s cogent rebuttal of Richard Dawkins’s attribution of consciousness to the responses engendered by AI (Letters, 10 May). That human consciousness appears to have an innate tendency to project itself on
