#008 Shallow Neural Network - Master Data Science


In this post we will see how to vectorize across multiple training examples. The outcome will be similar to what we saw in Logistic Regression. These equations tell us how, when given an input feature vector \(x \), we can generate predictions. If we have \(m \) training examples we need to repeat this proces \(m \) times. The notation \( a {[2](i)} \) means that we are talking about activation in the second layer that comes from \(i {th} \) training example.
