A year ago at London Tech Week, NVIDIA founder and CEO Jensen Huang and U.K. Prime Minister Keir Starmer made a declaration: the U.K. would be an AI maker, not an AI taker. At this year’s event, NVIDIA and its partners are showcasing how that commitment is producing real momentum across the nation’s infrastructure, startups […]
A Deep Dive into Calibration of Language Models: Platt Scaling, Isotonic Regression, Temperature Scaling
# Introduction A model that says it is 90% confident should be right 90% of the time. When that relationship breaks down, you get a miscalibration problem. The model’s scores stop telling you anything useful about reliability. For large language models (LLMs), miscalibration is widespread. A 2024 NAACL survey found that confidence scores diverge […]
We Should Train AI to Betray Its Users
The dilemma employee at an engineering company but have uncovered a deadly secret. Your company is performing ill-advised engineering activities that have already killed six contractors in a landslide. Despite this the company is pressing ahead, creating risks of further landslides, a catastrophic dam breach and/ or groundwater contamination. Instead of dealing with the problem, […]
Is this the dawn of the Tokenpocalypse?
Microsoft recently announced major pricing changes for GitHub Copilot — changes that were drastic enough that a Reddit user said their company has started calling it the Tokenpocalypse. On the latest episode of TechCrunch’s Equity podcast, Kirsten Korosec, Sean O’Kane, and I discussed what those changes might mean for the larger AI ecosystem. After all, […]
Google just redesigned the search box for the first time in 25 years — here’s why it matters more than you think.
In this article, you will learn how sentence embeddings work and how to build a fully client-side semantic search engine using Transformers.js, with no server, no API key, and no backend infrastructure required. Topics we will cover include: Building Semantic Search with Transformers.js and Sentence Embeddings Introduction You’ve probably shipped this bug before, where a […]
I switched my solid-state portable battery with this graphene heat dissipation one – here’s why
Microsoft AI Introduces MAI-Transcribe-1.5: 2.4% WER on Artificial Analysis, Best-in-Class FLEURS Accuracy, and Up to 5x Faster Long-Audio Transcription
Last week Microsoft AI has announced MAI-Transcribe-1.5. It is the second iteration of the company’s in-house speech-to-text family. The model targets accuracy across 43 languages, accents, and noisy environments. The Microsoft team positions it for production transcription workloads. What is MAI-Transcribe-1.5 MAI-Transcribe-1.5 is an automatic speech recognition (ASR) model. It takes audio as input and […]
Scientists are seriously asking if bees and ChatGPT are conscious
There are many different ways of studying consciousness. One of the most common is to measure how an animal – or artificial intelligence (AI) – acts. But two new papers on the possibility of consciousness in animals and AI suggest new theories for how to test this – one that strikes a middle ground between […]
The crucial human component in computing and AI
On April 30, the MIT Schwarzman College of Computing’s Social and Ethical Responsibilities of Computing (SERC) initiative hosted a full-day research symposium examining how artificial intelligence is shaping the world and its implications for society. The symposium included research talks by SERC’s latest seed grant recipients on topics such as air pollution forecasting and responsible computer vision deployment, panels on AI […]
