Overview of this book

Deep learning is rapidly becoming the most preferred way of solving data problems. This is thanks, in part, to its huge variety of mathematical algorithms and their ability to find patterns that are otherwise invisible to us. Deep Learning from the Basics begins with a fast-paced introduction to deep learning with Python, its definition, characteristics, and applications. You’ll learn how to use the Python interpreter and the script files in your applications, and utilize NumPy and Matplotlib in your deep learning models. As you progress through the book, you’ll discover backpropagation—an efficient way to calculate the gradients of weight parameters—and study multilayer perceptrons and their limitations, before, finally, implementing a three-layer neural network and calculating multidimensional arrays. By the end of the book, you’ll have the knowledge to apply the relevant technologies in deep learning.

Regularization

Overfitting often creates difficulties in machine learning problems. In overfitting, the model fits the training data too well and cannot properly handle other data that is not contained in the training data. Machine learning aims at generalizing performance. It is desirable for the model to properly recognize unknown data that is not contained in the training data. While you can create a complicated and representative model this way, reducing overfitting is also important:

Overfitting

The main two causes of overfitting are as follows:

  • The model has many parameters and is representative.
  • The training data is insufficient.

Here, we will generate overfitting by providing these two causes. Out of 60,000 pieces of training data in the MNIST dataset, only 300 are provided, and a seven-layer network is used to increase the network's complexity. It...
