WebApr 24, 2024 · Bootstrapping needs just a single transition, or a single tuple (state, action, next_state, reward) in order to perform a value (Q-value) update; thus learning can occur without a full episode of transitions. This is used in Q-learning type recursions. Since we are not waiting for a full episode to make an update, playing can be intertwined with learning. WebJan 12, 2016 · $\begingroup$ +1 for the nice overview of the two concepts.

WebCombining Active Learning and deep learning is hard. Deep neural networks aren’t really good at telling when they are not sure. The output from the final softmax layer tends to be over confident. Deep neural networks are computationally heavy, so you usually want to select a batch with many images to annotate at once.
