To get the most out of this book

All code examples are hosted on Kaggle. You can use Kaggle for free and get access to a GPU, which will enable you to run the example code much faster. If you do not have a very powerful machine with a GPU, it will be much more comfortable to run the code on Kaggle. You can find links to all notebooks on this book's GitHub page: https://github.com/PacktPublishing/Machine-Learning-for-Finance.

This book assumes some working knowledge of mathematical concepts such as linear algebra, statistics, probability theory, and calculus. You do not have to be an expert, however.

Equally, knowledge of Python and some popular data science libraries such as pandas and Matplotlib is assumed.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in the text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. For example; "Mount the downloaded WebStorm-10*.dmg disk image file as another disk in your system."

A block of code is set as follows:

import numpy as np
x_train = np.expand_dims(x_train,-1)
x_test = np.expand_dims(x_test,-1)
x_train.shape

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

from keras.models import Sequential
img_shape = (28,28,1)
model = Sequential()
model.add(Conv2D(6,3,input_shape=img_shape))

Any command-line input or output is written as follows:

Train on 60000 samples, validate on 10000 samples
Epoch 1/10
60000/60000 [==============================] - 22s 374us/step - loss: 7707.2773 - acc: 0.6556 - val_loss: 55.7280 - val_acc: 0.7322

Bold: Indicates a new term, an important word, or words that you see on the screen, for example, in menus or dialog boxes, also appear in the text like this. For example: "Select System info from the Administration panel."
