In the last chapter we learned that deep neural networks are often much harder to train than shallow neural networks. That's unfortunate, since we have good reason to believe that if we could train deep nets they'd be much more powerful than shallow…

Writing thread-safe code is managing access to state and in particular to shared, mutable state. Object's state is its data, stored in state variables such as instance or static fields. Whether an object needs to be thread-safe depends on whether it…

Stochastic Optimization Techniques Neural networks are often trained stochastically, i.e. using a method where the objective function changes at each iteration. This stochastic variation is due to the model being trained on different data during each…
