Overview of this book

Most organizations exhibit a time-dependent structure in their processes, including fields such as finance. By leveraging time series analysis and forecasting, these organizations can make informed decisions and optimize their performance. Accurate forecasts help reduce uncertainty and enable better planning of operations. Unlike traditional approaches to forecasting, deep learning can process large amounts of data and help derive complex patterns. Despite its increasing relevance, getting the most out of deep learning requires significant technical expertise. This book guides you through applying deep learning to time series data with the help of easy-to-follow code recipes. You’ll cover time series problems, such as forecasting, anomaly detection, and classification. This deep learning book will also show you how to solve these problems using different deep neural network architectures, including convolutional neural networks (CNNs) or transformers. As you progress, you’ll use PyTorch, a popular deep learning framework based on Python to build production-ready prediction solutions. By the end of this book, you'll have learned how to solve different time series tasks with deep learning using the PyTorch ecosystem.

Prediction-based anomaly detection using DL

We continue to explore prediction-based methods in this recipe. This time, we’ll create a forecasting model based on DL. Besides, we’ll use the point forecasts’ error as a reference for detecting anomalies.

Getting ready

We’ll use a time series dataset about the number of taxi trips in New York City. This dataset is considered a benchmark problem for time series anomaly detection tasks. You can check the source at the following link: https://databank.illinois.edu/datasets/IDB-9610843.

Let’s start by loading the time series using pandas:

from datetime import datetime
import pandas as pd
dataset = pd.read_csv('assets/datasets/taxi/taxi_data.csv')
labels = pd.read_csv('assets/datasets/taxi/taxi_labels.csv')
dataset['ds'] = pd.Series([datetime.fromtimestamp(x) 
    for x in dataset['timestamp']])
dataset = dataset.drop('timestamp&apos...
