Analogies Emerge from Learning Dyamics in Neural Networks


When a neural network is trained on multiple analogous tasks, previous research has shown that it will often generate representations that reflect the analogy. This may explain the value of multi-task training, and also may underlie the power of human analogical reasoning -- awareness of analogies may emerge naturally from gradient-based learning in neural networks. We explore this issue by generalizing linear analysis techniques to explore two sets of analogous tasks, show that analogical structure is commonly extracted, and address some potential implications.
