Sparse Federated Representation Learning for deep-sea exploration habitat design with inverse simulation verification A Personal Voyage into the Abyss of Distributed AI It was 3 AM on a Tuesday when I found myself staring at a heatmap of underwater pressure distributions, generated not from oceanographic sensors but from a federated learning model I had been training for weeks. The task was deceptively simple: design a deep-sea exploration habitat that could withstand the crushi...
