Amin Vahdat has been promoted to chief technologist for AI infrastructure, a newly created position reporting directly to CEO Sundar Pichai.
Annotating regions of interest in medical images, a process known as segmentation, is often one of the first steps clinical researchers take when running a new study involving biomedical images. For instance, to determine how the size of the brain’s hippocampus changes as patients age, the scientist first outlines each hippocampus in a series of brain scans. For many structures and image types, this is often a manual process that can be extremely time-consuming, especially if the regions […]
In early September, EFF submitted an amicus brief to Ecuador’s Constitutional Court supporting a constitutional challenge filed by Ecuadorian NGOs, including INREDH and LaLibre. The case challenges the constitutionality of the Ley Orgánica de Inteligencia (LOI) and its implementing regulation, the General Regulation of the LOI. EFF’s amicus brief argues that the LOI enables disproportionate surveillance and secrecy that undermine constitutional and Inter-American human rights standards. EFF urges the Constitutional Court to declare the LOI and its regulation […]
This article introduces the Gaussian Mixture Model as a natural extension of k-Means, by improving how distance is measured through variances and the Mahalanobis distance. Instead of assigning points to clusters with hard boundaries, GMM uses probabilities learned through the Expectation–Maximization algorithm – the general form of Lloyd’s method. Using simple Excel formulas, we implement EM step by step in 1D and 2D, and we visualise how the Gaussian curves or ellipses move during training. The means shift, […]
Let’s say an environmental scientist is studying whether exposure to air pollution is associated with lower birth weights in a particular county. They might train a machine-learning model to estimate the magnitude of this association, since machine-learning methods are especially good at learning complex relationships. Standard machine-learning methods excel at making predictions and sometimes provide uncertainties, like confidence intervals, for these predictions. However, they generally don’t provide estimates or confidence intervals when determining whether two variables are related. […]
Author(s): Manash Pratim Originally published on Towards AI. Stop watching 20 minutes of “Hey guys, welcome back!” just to find one function. I have a confession. Image generated using AIThe article discusses the author’s development of a tool that efficiently extracts code from YouTube coding tutorials by utilizing the hidden transcripts that accompany the videos. The author details the motivation behind creating this tool, the technical stack used, and provides an overview of its efficacy, demonstrating significant time […]
French AI startup Mistral today launched Devstral 2, a new generation of its AI model designed for coding, as the company seeks to catch up to bigger AI labs like Anthropic and other coding-focused LLMs.
ElevenLabs has made a name for itself building realistic AI voices. What started as two Polish engineers annoyed by terrible movie dubbing has grown into a profitable company now valued at $6.6 billion, doubling from just nine months ago. The company recently announced a $100 million tender offer led by Sequoia and ICONIQ, with participation from a16z and others, as […]
Empromptu claims all a user has to do is tell the platform’s AI chatbot what they want — like a new HTML or JavaScript app — and the AI will go ahead and build it.
Artificial intelligence, once the realm of science fiction, claimed its place at the pinnacle of scientific achievement Monday in Sweden. In a historic ceremony at Stockholm’s iconic Konserthuset, John Hopfield and Geoffrey Hinton received the Nobel Prize in Physics for their pioneering work on neural networks — systems that mimic the brain’s architecture and form the bedrock of modern AI. Meanwhile, Demis Hassabis and John Jumper accepted the Nobel Prize in Chemistry for Google DeepMind’s AlphaFold, a system […]
