Overview of this book

Beyond buzzwords like Big Data or Data Science, there are a great opportunities to innovate in many businesses using data analysis to get data-driven products. Data analysis involves asking many questions about data in order to discover insights and generate value for a product or a service. This book explains the basic data algorithms without the theoretical jargon, and you’ll get hands-on turning data into insights using machine learning techniques. We will perform data-driven innovation processing for several types of data such as text, Images, social network graphs, documents, and time series, showing you how to implement large data processing with MongoDB and Apache Spark.

Preface

Chapter 8. Working with Support Vector Machines

The Support Vector Machine (SVM) is a powerful classification technique based on Kernels, such as the Kernel Ridge Regression (KRR) algorithm seen in the previous chapter. We often deal with sparse datasets or with data that is not good enough to make a good prediction or classification. In such cases, we may use a technique that creates new values from the original dataset to help in the accuracy of the algorithm; this new data is called synthetic. Due to their efficiency, using Kernels is one of the most common methods to make synthetic data. In this chapter, we will provide you with an easy way to get acceptable results using SVM. We will perform a dimensionality reduction of the dataset, and we will produce a model for classification.

The theoretical foundation of SVM lies in the work of Vladimir Vapnik and the theory of statistical learning developed in the 70s. SVMs are highly used in pattern recognition of Time Series, Bioinformatics...
