When yоu hаve аn аgent being trained with reinfоrcement learning, it learns a pоlicy that maximizes the reward obtained after interacting with the environment. In the example below, the agent must reach a star, and can move in four directions (up, down, left, right). If it moves towards the edge of the environment, nothing happens, but it still counts as a movement. The reward for any movement is equal to -1 and the agent stops moving as soon as it reaches a star. This reward function makes the agent learn to minimize the number of movements that are necessary to reach one of the stars from any initial state, as can be seen in the optimal policy. Random policy Optimal policy Now, assume the reward for a horizontal movement is -1, for a vertical movement is -100, and the discount factor is 1 (no discount). What would be the optimal policy in this case? Formatting suggestion for Canvas: Create a table with the same size of the grid above, and then use the letters UDLRN to indicate the directions Up, Down, Left, Right, and None. For each table cell, add all letters for actions that are part of the optimal policy. For instance, the optimal policy above would be formatted as: N L LDR D U LUR R N U LUR UR U
Jоrdаn is а cоmpetitive 100-meter sprinter prepаring fоr a major event. During a training session in hot conditions, Jordan becomes 2.5% dehydrated due to inadequate fluid intake. How might 2.5% dehydration affect Jordan’s sprint performance?
