MIT: Pioneering the Next 250 Years

President Sally Kornbluth warns of innovation pipeline drying up without federal support for curiosity-driven research. She emphasizes the importance of teaching foundational skills for leading in an AI-enabled world.

Regression Rumble: Kernel vs. Support Vector Machines

Kernel ridge regression (KRR) and support vector regression (SVR) yield similar results, with KRR being simpler and more efficient than SVR due to fewer hyperparameters. While KRR stores all training items, SVR only stores a subset, making it slightly faster in predictions.

Streamlining Amazon Bedrock Model Access

Manage AI model access across multiple AWS accounts using managed entitlements for Amazon Bedrock, eliminating the need for AWS Marketplace permissions in member accounts. This approach streamlines distribution, ensuring teams can access third-party models like Anthropic Claude or Cohere while maintaining centralized governance and avoiding operational overhead.
