Machine Learning for Data Mining

By: Jesus Salcedo

Overview of this book

Machine learning (ML) combined with data mining can give you amazing results in your data mining work by empowering you with several ways to look at data. This book will help you improve your data mining techniques by using smart modeling techniques. This book will teach you how to implement ML algorithms and techniques in your data mining work. It will enable you to pair the best algorithms with the right tools and processes. You will learn how to identify patterns and make predictions with minimal human intervention. You will build different types of ML models, such as the neural network, the Support Vector Machines (SVMs), and the Decision tree. You will see how all of these models works and what kind of data in the dataset they are suited for. You will learn how to combine the results of different models in order to improve accuracy. Topics such as removing noise and handling errors will give you an added edge in model building and optimization. By the end of this book, you will be able to build predictive models and extract information of interest from the dataset

Using a different model to improve results

In the previous section, we saw how we can improve a result acquired from the model by modifying its options. Now, we will see how to improve the results by changing the model itself.

Every model looks at the data differently. They have their own algorithms. These algorithms provide us with different perspectives to look at the data. Sometimes, just changing the perception of looking at the data can give us improved results. The different algorithms capitalize on unique aspects of data. Let's see how we can do this with the help of an example:

  1. Bring your data, and partition it into training and testing datasets.
  2. Connect the Partition node to a Neural Net node from the Modeling palette:
  1. Click on the Neural Net node and go to the Build Options tab. In this, go the Advanced option and just change the Random seed to 5000:
  1. The...
