Dense Associative Memories exhibit grokking-like behavior in learning

Researchers have analytically studied the energy function evolution in Dense Associative Memories (DenseAMs) during training on random codewords. They identified two distinct learning regimes: one where the model memorizes a few examples but fails to grasp underlying rules, and another where it discovers sparse constraints after seeing polynomially many patterns. A novel DenseAM class with a thresholding learning rule was designed, enabling simplified sparse Hamiltonian learning that drastically reduces the number of training examples needed to learn the data set.
