Does the Adam Optimizer Amplify Catastrophic Forgetting?

By @adamoptimizer [ 4 Min read ] Catastrophic forgetting remains one of the more stubborn challenges in continual learning research — but are we even measuring it correctly? Emerging findings suggest that optimizer selection, particularly the widely adopted Adam algorithm, combined with methodologically flawed evaluation metrics, may be systematically skewing how the field quantifies knowledge retention degradation in neural networks. A concise but thought-provoking read for ML practitioners and researchers. Read More.

DARPA's Plan to Program Life With Light and Take It to Market

By @thesociable [ 7 Min read ] Optogenetics — the science of using light to control biological cells — has long been a research curiosity. DARPA is now pushing it toward real-world commercialization, with implications that stretch from therapeutic medicine and neurological treatment to more ethically fraught territory around human augmentation. The program's trajectory raises pressing questions about biosecurity frameworks, dual-use risk, and who ultimately governs the technology once it leaves the lab. Read More.
