It’s refreshingly honest There is no shortage of AI bots on Telegram. Perplexity AI’s bot will answer your questions with sourced references. TelegramGPT wraps ChatGPT in a convenient chat interface. Dozens of others offer variations on the same theme: you type a prompt, you get a response, you move on. The Portal One+ Telegram bot assistant, built on the OpenClaw runtime, aims to be fundamentally different. It doesn’t just answer questions – it lives on your machine, remembers […]

Hi all, I’ve been studying causal inference (mainly through Elias Bareinboim’s lectures) and understand the theoretical side — structural causal models (SCMs), do-calculus, identifiability, backdoor/frontdoor criteria, etc. However, I’m struggling with the implementation side of Causal RL. Most material I’ve found focuses on: – Theorems about identifiability – Action space pruning – Counterfactual reasoning concepts But I’m not finding concrete examples of: How to incorporate a known causal graph into an RL training loop How to parameterize the […]

Data-efficient neural decoding is a central challenge for speech brain-computer interfaces. We present the first demonstration of transfer learning and cross-task decoding for MEG-based speech models spanning perception and production. We pre-train a Conformer-based model on 50 hours of single-subject listening data and fine-tune on just 5 minutes per subject across 18 participants. Transfer learning yields consistent improvements, with in-task accuracy gains of 1-4% and larger cross-task gains of up to 5-6%. Not only does pre-training improve performance […]

We review recent advances in machine learning (ML) force-field methods for Landau-Lifshitz-Gilbert (LLG) simulations of itinerant electron magnets, focusing on scalability and transferability. Built on the principle of locality, a deep neural network model is developed to efficiently and accurately predict the electron-mediated forces governing spin dynamics. Symmetry-aware descriptors constructed through a group-theoretical approach ensure rigorous incorporation of both lattice and spin-rotation symmetries. The framework is demonstrated using the prototypical s-d exchange model widely employed in spintronics. ML-enabled […]
