Topics in Building the Neural Network

1

Core Ideas of Keras and TensorFlow

  • Keras is a high-level neural network API in Python that simplifies constructing and training neural networks.
  • TensorFlow is an open-source, end-to-end platform for Machine Learning.
  • TensorFlow is primarily developed by the Google Brain Team.
2

Five-Step Keras Workflow

  • Creating a neural network in Keras involves a standard five-step workflow.
  • Step 1 is Prepare Data: load the dataset and reshape or normalize it.
  • Step 2 is Define Model: stack layers to create the architecture.
3

Layers and Model Building

  • The Sequential model is a linear stack of layers and is the easiest way to define a model architecture.
  • Dense layer is a fully connected layer where every neuron is connected to every neuron in the previous layer.
  • Dense layer performs the heavy lifting of learning patterns.
4

Activation Functions, Loss Functions, and Optimizer

  • ReLU introduces non-linearity and is used in hidden Dense layers.
  • Sigmoid activation is used in the output layer for binary classification with a single unit.
  • Softmax activation is standard for multi-class classification because it gives a probability distribution summing to 1.
