i’m trying to train an ASR model using the LibriSpeech recipe from SpeechBrain (without the language model) on a 100-hour dataset of dialectal Arabic speech. the model architecture uses a Conformer-small encoder and a Transformer decoder, with a total of around 13M parameters. the recipe uses a combination of two loss functions: CTC and KL divergence, specifically: 0.3 * CTC + 0.7 * KLDiv during training, both losses drop significantly during the first few weight updates, but then […]

In this tutorial, we build a governed AI-agent workflow using Microsoft’s Agent Governance Toolkit as the reference point. We create a Colab-ready implementation where agents do not directly execute tools; instead, every action first passes through a governance layer that checks the agent’s identity, trust score, risk tier, requested tool, action type, sensitivity level, and policy rules. We define a YAML-based policy that controls destructive database operations, external email sending, shell execution, access to sensitive data, and financial […]

I have about 10 years of experience in RL, though I haven’t been active in the field for the past 2 years. Recently, I’ve been thinking about getting back into robotics, and your post caught my attention. I’m looking to get my hands dirty again, specifically with VLA. My goal is to pick a problem, replicate something that already works end-to-end, and document it well. Here’s roughly what I want to do: – Pick a task (preferably simulation) […]

so I heard that recroom a popular VR game is shutting down would it be possible to for example record data from in-game states (screenshots fps) and the orientation and velocity of the vr headset. and using the data train a world model?. I know that it would be very hard I am just wondering if it could be positive. submitted by /u/tryfonas_1_ [link] [comments]

The solution might be cancelling my AI subscription I find this post by David Wilson very relatable. David lists 16+ projects he’s spun up with AI tooling, and concludes: I didn’t mean to build most of these things. Usually the Claude session started with something like “write a quick script for X“, and one hour later the result is not a quick script for X, nor in the usual case is my problem solved, whatever the original itch […]

Key Highlights: The expected announcements focus on three major categories that have become increasingly important in the AI market: image generation, speech recognition, and voice synthesis. The upcoming releases build on Microsoft’s existing MAI family: MAI-Image-2, MAI-Transcribe-1, and MAI-Voice-1. If these reports prove to be accurate, the new generation will bring expanded capabilities and reduce Microsoft’s reliance on third-party AI providers by strengthening its own model ecosystem.  New MAI Models Expected at Build 2026 BUILD 🔥: Microsoft is […]

NotebookLM stands out because it lets users upload documents, notes, PDFs, and more, then automatically generate summaries, answers, and study guides which is something most general AI chatbots don’t do. But these new discoveries hint that Google wants to turn NotebookLM into much more than just a document analyzer. Reports point to three big features in development: Personal Preferences, Connectors, and Canvas. Together, they could turn NotebookLM into a hub for research, managing information, and actually creating content. […]

Key Highlights: Meta’s newest wearable aims to make always on digital assistance a reality. Meta is building a pendant style device designed to record conversations nonstop, turn them into transcripts, and generate AI summaries of your daily interactions. This device marks another step in Meta’s bet on artificial intelligence hardware. The company already has AI smart glasses in the market, but the pendant points to a broader ambition, one in which AI serves as a personal assistant that […]

The function (1 + cos(x))/2 gives a fair approximation to the Gaussian density exp(−x²) You can make the approximation much better by raising it to a power. The function ((1 + cos(x))/2)4 gives a good lower bound and ((1 + cos(x))/2)3.5597 gives a good upper bound. More on that here. There are other ways of improving the cosine approximation to the Gaussian. Yesterday I came across one I hadn’t seen before, adding a sin(x) term to x. (1 + […]
