![]() ![]() The backpropagation algorithm can be used to train large neural networks efficiently. Ideally, we would like to be able to efficiently train large RNN-based agents. The credit assignment problem tackles the problem of figuring out which steps caused the resulting feedback-which steps should receive credit or blame for the final result?, which makes it hard for traditional RL algorithms to learn millions of weights of a large model, hence in practice, smaller networks are used as they iterate faster to a good policy during training. The RL algorithm is often bottlenecked by the credit assignment problem In many RL problems, the feedback (positive or negative reward) is given at end of a sequence of steps. However, many model-free RL methods in the literature often only use small neural networks with few parameters. Large RNNs are highly expressive models that can learn rich spatial and temporal representations of data. In many reinforcement learning (RL) problems, an artificial agent also benefits from having a good representation of past and present states, and a good predictive model of the future, preferably a powerful predictive model implemented on a general purpose computer such as a recurrent neural network (RNN). According to cartoonist and comics theorist Scott McCloud, “ in the world of comics, time and space are one and the same.” Art © Scott McCloud. We learn to perceive time spatially when we read comics. They can quickly act on their predictions of the future without the need to consciously roll out possible future scenarios to form a plan. Their muscles reflexively swing the bat at the right time and location in line with their internal models' predictions. For professional players, this all happens subconsciously. The reason we are able to hit a 100mph fastball is due to our ability to instinctively predict when and where the ball will go. A baseball batter has milliseconds to decide how they should swing the bat - shorter than the time it takes for visual signals from our eyes to reach our brain. We are able to instinctively act on this predictive model and perform fast reflexive behaviours when we face danger, without the need to consciously plan out a course of action. One way of understanding the predictive model inside of our brains is that it might not be about just predicting the future in general, but predicting future sensory data given our current motor actions.
