Course Overview

Artificial intelligence and machine learning are defining features of the 21st century and are quickly becoming a key factor in gaining and maintaining competitive advantage in each industry which incorporates them.

In this course, we combine conceptual knowledge of machine learning with extensive experience applying it to real-world data. Your team will develop skills in applying Python’s machine learning tools, such as the scikit-learn package, to make predictions about complicated phenomena by leveraging the information contained in numerical data, natural language, images, and discrete categories.

The emphasis is on learning techniques to maximize the predictive performance of machine learning workflows. After building a solid foundation in the Python scientific stack, we focus on the different types of feature sources for machine learning. For each, we progress through a short introductory lecture followed by exercises of progressive difficulty. Intermingled with the machine learning material are short discussions of helpful and diagnostic data visualizations.

Days 1–3: Python Foundations

  • It begins with a one-day introduction to the Python language focusing on standard data structures, control constructs, and code organization.
  • After a brief overview of the Scientific Python ecosystem, we dive into techniques for numeric data processing, including efficiently manipulating and processing large data sets using NumPy arrays and data visualization with 2D plots using Matplotlib.
  • Next up is an introduction to Pandas to efficiently load, clean, normalize, aggregate, transform, and visualize data.

Days 4–5: Machine Learning with scikit-learn, and Data Visualization

  • Use specific regression, classification, and clustering algorithms skillfully to model data and solve problems by leveraging the full power of the scikit-learn API
  • Extract relevant information from images using scikit-image
  • Extract lexical and semantic information from natural language data
  • Engineer numeric features to maximize predictive power
  • Visualize interactions and non-linear distributions of data using matplotlib and seaborn
  • Validate models with the appropriate success metrics
  • Troubleshoot common issues like unbalanced labels and high dimensionality data
  • Build deep insight by retrieving model parameters

    Course Syllabus & Topics

    This class is taught in real-time by an Enthought Trainer.



    Course Prerequisites

    Experience with Python is helpful (but not required). However, programming experience in some language (such as R, MATLAB, SAS, Mathematica, Java, C, C++, VB, or FORTRAN) is expected. In particular, participants need to be comfortable with general programming concepts like variables, loops, and functions.

    Collapse All

    1. Introduction to Python

    We kick off the class by exploring the functionality of the IPython Shell, an enhanced interactive science-centric console. Next we review the Jupyter Notebook, a cell-based environment that renders scripts, plots, and rich media in a web-like interface, making it ideal for sharing and publishing analysis with peers. You’ll leave with a mastery of these tools that will accelerate your productivity and facilitate collaboration.

    • Data-Types (strings, lists, dictionaries and more)
    • Control Flow (if-then statements, looping)
    • Organizing code (functions, modules, packages)
    • Reading and writing files

    2. Introduction to NumPy and 2D plotting

    The NumPy package is presented as a tool for rapidly manipulating and processing large data sets. 2D plotting is introduced with matplotlib.

    • Plotting with matplotlib
    • Understanding the N-dimensional data structure
    • Creating arrays
    • Indexing arrays by slicing or more generally with indices or masks
    • Basic operations and manipulations on N-dimensional arrays

    3. Time series analysis and data manipulation with Pandas

    Built on top of NumPy arrays, the Python Data Analysis Library (Pandas) is a powerful and convenient package for dealing with multi-dimensional datasets. Participants will learn about its powerful data aggregation and reorganization capabilities for data set explorations, including support for labeling data along each dimension, missing values, and time series manipulations.

    • Pandas I/O operations
    • Pandas 1D and 2D data structures (Series and DataFrame)
