Details

Portia Burton will give a brief overview of machine learning, the k-nearest neighbor algorithm and scikit-learn. Sometimes developers need to make decisions, even when they don't have all of the required information. Machine learning attempts to solve this problem by using known data (a training data sample) to make predictions about the unknown. For example, usually a user doesn't tell Amazon explicitly what type of book they want to read, but based on the user's purchasing history, and the user's demographic, Amazon is able to induce what the user might like to read.

Scikit-learn makes use of the k-nearest neighbor algorithm and allows developers to make predictions. Using training data one could make inferences such as what type of food, tv show, or music the user prefers. In this presentation we will introduce the k-nearest neighbor algorithm, and discuss when one might use this algorithm.
