Data is all around us - in every industry and academic field, behind every online purchase recommendation and driving route calculation. Sometimes we have more data than we know what to do with. If solving data problems intrigues you (or if you just need some data for a class project...), check out the links below.
☞ RSVP for the Python workshops.
Workshops are offered in either Alexander Library or LSM (with identical content). Participants in LSM-based workshops must bring their own laptops. At Alexander, you can either bring your own laptop, or use the desktops in the lab.
Python Basics and Data Exploration
This workshop will be an accelerated introduction to fundamental concepts such as variable assignment, data types, basic calculations, working with strings and lists, control structures (e.g. for-loops), functions. We will also start working with pandas, a popular data science library in Python, to explore a dataset on foodborne outbreaks reported to the CDC.
Data Manipulation and Analysis with Python
In this workshop, we will dive into the world of arrays and data frames using the NumPy and pandas libraries. We'll cover data cleaning and pre-processing, joining and merging, group operations, and more. If you work with tabular data, this workshop is for you!
Data Visualization and Machine Learning with Python
Interested in finding patterns and predicting unknown attribute values in your data? Join us for an overview of machine learning techniques implemented using the scikit-learn library. We'll also learn how to do data visualization with matplotlib, a popular plotting library in Python.
Data Scraping: Interaction with APIs with Python
This workshop is intended to show how to use Python to interact with third-party APIs for data collection. Different type of APIs with real applications will be introduced. Examples such as Rest API for FRED and Quandl will be discussed. A project regarding interacting with FRED API and merging with historical data will be demonstrated in detail.
Data Mining: Regression and Classification with Python
The traditional Least Square estimation, KNN face severe overfitting issues when the dataset has high-dimensional features. Modern data mining regression techniques such as lasso and classification techniques such as SVM gives a better estimation result in such a situation. The workshop intends to show how lasso and SVM works in Python. Compare the estimation result of Lasso with least square estimation, SVM with KNN in the high-dimensional setting.
Machine Learning: Building a Neural Network from Scratch
This workshop is intended to help you establish a Neural Network mindset, and hone your intuitions about Deep Learning. We start by building a logistic regression as the baseline model to recognize cats. Then we develop a single hidden layer NN and extend to a deep NN by adding as many hidden layers as you want. Hopefully, you will see an improvement in accuracy relative to previous logistic regression.

Since Python is open source, there are abundant online resources to help learners find their way around the language. If you have a specific programming task you need help to achieve, a Google search is often the best way to start. Here is a list of resources you may find helpful if you're interested in a particular topic!
