Microsoft Rolls Out In-House AI Models to Take on OpenAI

Microsoft Rolls Out In-House AI Models to Take on OpenAI

Tech giant Microsoft (MSFT) has begun testing its in-house artificial intelligence (AI) models that will compete directly with partner OpenAI while also reducing reliance on the ChatGPT maker. The company has launched two customer-focused AI models under its MAI (Microsoft Artificial Intelligence) brand, named MAI-Voice-1 and MAI-1-preview. The announcement was made by Microsoft AI CEO Mustafa Suleyman in an X …

Microsoft introduces a pair of in-house AI models

Microsoft is expanding its AI footprint with the of two new models that its teams trained completely in-house. MAI-Voice-1 is the tech major’s first natural speech generation model, while MAI-1-preview is text-based and is the company’s first foundation model trained end-to-end. MAI-Voice-1 is currently being used in the Copilot Daily and Podcast features. Microsoft has made MAI-1-preview available for public …

Optical generative models | Nature

Snapshot optical image generation process The snapshot optical generation procedure includes two parts: the digital encoder and the optical generative model. For image generation of MNIST, Fashion-MNIST, Butterflies-100 and Celeb-A, the digital encoder architecture that we selected is a variant of the multi-layer perceptron54, which contained Ld fully connected layers, each of which was followed by a subsequent activation function …

Simpler models can outperform deep learning at climate prediction | MIT News

Simpler models can outperform deep learning at climate prediction | MIT News

Environmental scientists are increasingly using enormous artificial intelligence models to make predictions about changes in weather and climate, but a new study by MIT researchers shows that bigger models are not always better. The team demonstrates that, in certain climate scenarios, much simpler, physics-based models can generate more accurate predictions than state-of-the-art deep-learning models. Their analysis also reveals that a …

30 Years of Satellite Data Confirm Predictions from Early Models of Sea Level Rise

30 Years of Satellite Data Confirm Predictions from Early Models of Sea Level Rise

“The ultimate test of climate projections is to compare them with what has played out…” says earth sciences professor Torbjörn Törnqvist, lead author on a new study published in the open-access journal Earth’s Future (published by the American Geophysical Union). But after “decades of observations,” he says his researchers “were quite amazed how good those early projections were, especially when …
