Overview of this book

The volume, diversity, and speed of data available has never been greater. Powerful machine learning methods can unlock the value in this information by finding complex relationships and unanticipated trends. Using the Python programming language, analysts can use these sophisticated methods to build scalable analytic applications to deliver insights that are of tremendous value to their organizations. In Mastering Predictive Analytics with Python, you will learn the process of turning raw data into powerful insights. Through case studies and code examples using popular open-source Python libraries, this book illustrates the complete development process for analytic applications and how to quickly apply these methods to your own data to create robust and scalable prediction services. Covering a wide range of algorithms for classification, regression, clustering, as well as cutting-edge techniques such as deep learning, this book illustrates not only how these methods work, but how to implement them in practice. You will learn to choose the right approach for your problem and how to develop engaging visualizations to bring the insights of predictive modeling to life

Tree methods

In many datasets, the relationship between our inputs and output may not be a straight line. For example, consider the relationship between hour of the day and probability of posting on social media. If you were to draw a plot of this probability, it would likely increase during the evening and lunch break, and decline during the night, morning and workday, forming a sinusoidal wave pattern. A linear model cannot represent this kind of relationship, as the value of the response does not strictly increase or decrease with the hour of the day. What models, then, could we use to capture this relationship? In the specific case of time series models we could use approaches such as the Kalman filter described above, using the components of the structural time series equation to represent the cyclical 24-hour pattern of social media activity. In the following section we examine more general approaches that will apply both to time series data and to more general non-linear relationships...
