True. There exists a convergence proof. - Answer K-means is a clustering algorithm that is guaranteed to converge. 
 
False. A delayed reinforcement learning task is one where the optimal solution can only be found by associating incoming rewards with a whole sequence of previous actions, instead of just the latest one. The reward may very well be received in every time step also in delayed reinforcement learning. - Answer The main difference between immediate and delayed reinforcement lea...
