Question
In Linux, you have file, kevin.txt, how do you print out the lines on cmd terminal in reverse (last line first, first line last)?

4. Basic Commands
B pieces. Its sister, csplit , can split files along specified lines of text within the file. The commands are seldom used on their own but are very useful within programs that manipulate text. <span>tac <filename> [<filename> ...] Writes the contents of all the files listed to the screen, reversing the order of the lines--that is, printing the last line of the file first. t

Batch normalization (Ioffe & Szegedy (2015)), a technique that inserts layers into the the deep net that transform the output for the batch to be zero mean unit variance, has successfully facilitated training of the twenty-two layer GoogLeNet (Szegedy et al. (2015)). However, batch normalization adds a 30% computational overhead to each iteration.

Exact numbers vary from run to run, but in the most cases, batch normalization put after non-linearity performs better

the LSUV-initialized GoogLeNet learns faster than hen then original one and shows better test accuracy all the time – see Figure 5. The final accuracy is 0.680 vs. 0.672 respectively
