NN paper mistake report

[DutyCat]

Describe the bug in 《Deep Neural Network for Collaborative Machine Learning with Additively Homomorphic Encryption》paper，there are two oblivious mistakes。 1）at algorithm 1,original description is “ai ← σ(W2x)”，it should be "ai ← σ(W1x)". 2）at section3.4，the learning rate η should be outing of the bracket。
