Change batch size and epochs for NCF benchmarks
Change batch size and epochs for NCF benchmarks

Current batch size 160000 does not converge to the desired HR. So we decrease to 99k which is known to converge. Tested locally and got to 63.5 at epoch 7. Also decreasing number of epochs as I don't see any improvement after epoch 7-8.
