 a small region around the target value and an L1 penalty further away.

**Periodic Target Q Value Updates**. The last modification suggested in Mnih et al. also aims to reduce correlations between updates and the immediately undertaken behavior. The idea is to freeze the Q network once in a while into a frozen, copied network \\(\hat{Q}\\) which is used to only compute the targets. This target network is once in a while updated to the actual current \\(Q\\) network. That is, we use the target network \\(r\
