Hands-On Data Science with Anaconda

By: Yuxing Yan, James Yan

Overview of this book

Anaconda is an open source platform that brings together the best tools for data science professionals with more than 100 popular packages supporting Python, Scala, and R languages. Hands-On Data Science with Anaconda gets you started with Anaconda and demonstrates how you can use it to perform data science operations in the real world. The book begins with setting up the environment for Anaconda platform in order to make it accessible for tools and frameworks such as Jupyter, pandas, matplotlib, Python, R, Julia, and more. You’ll walk through package manager Conda, through which you can automatically manage all packages including cross-language dependencies, and work across Linux, macOS, and Windows. You’ll explore all the essentials of data science and linear algebra to perform data science tasks using packages such as SciPy, contrastive, scikit-learn, Rattle, and Rmixmod. Once you’re accustomed to all this, you’ll start with operations in data science such as cleaning, sorting, and data classification. You’ll move on to learning how to perform tasks such as clustering, regression, prediction, and building machine learning models and optimizing them. In addition to this, you’ll learn how to visualize data using the packages available for Julia, Python, and R.

Unsupervised Learning in Anaconda

Before discussing unsupervised learning, it might be a good idea to introduce supervised learning since most of us will be familiar with functions discussed in the previous chapters. For a function of y=f(x), usually we have values for independent variables of x1, x2, ... xn and a set of corresponding values for a dependent variable of y. In previous chapters, we have discussed various types of functions, such as the single-factor linear model. Our task is to figure out the format of the function, given a set of input values. For supervised learning, we have two datasets: the training data and test data. For the training dataset, it has a set of input variables and related output values (also called a supervisory signal). A supervised learning algorithm analyzes the training data and produces an inferred function. Then, we apply this inferred...
