With Google recently releasing a generative AI-powered search bot called Bard to rival Microsoft's "new Bing" search experience, we put both to the test, feeding them identical questions about Visual Studio and .NET.
GPT-4, the advanced generative AI model from Microsoft partner OpenAI, is now powering the new GitHub Copilot X and the Azure OpenAI Service.
Microsoft shipped TypeScript 5.0 with new features claimed to make the language smaller, simpler and faster.
A new tool that can generate code is being previewed in the Visual Studio Code Insiders channel seeks to ease the tedious data preparation process that data scientists need to go through to get good data for successful analysis projects.
Decision trees are useful for relatively small datasets that have a relatively simple underlying structure, and when the trained model must be easily interpretable, explains Dr. James McCaffrey of Microsoft Research, who provides step-by-step instructions and full source code.
