In the previous scenarios, you've learned the central concepts of the Machine Learning process and created few layer for the neural network architecture. The network didn't perform well because we didn't apply any training yet.

In this scenario, we will do the walkthrough of the Deep Learning process. We will start from loading the data and building the layers. Then we'll use forward- and backpropagation in the training process.

Congratulations!

You've completed Neural Network Training scenario.

You've learned how to accomplish the following tasks using Python numpy library:

  • Loading the data from the csv file
  • Building the fully connected layers for the Neural Network
  • Applying forward- and backpropagation
  • Training the network

Don’t stop now! The next scenario will only take about 10 minutes to complete.

Neural Network Training

Step 1 of 6

Neural Network Architecture

Let's build our first Deep Learning process. We will use the flower shaped dataset to accomplish this task. As we said, the data is not linearly separable. This means that algorithms that rely on the straight lines to separate classes won't be of much help.

Dataset

When building a neural network for the case like this, it means we need to introduce hidden layers. The final architecture looks like the one in the image.

Network architecture

In the next steps we will load the data, build the network and train it to make future predictions.
