Don't miss this Big Data Analytics Meetup with talks from Nikolay Manchev and Chris Snow.
In this session, we provide a high level introduction to Collaborative Filtering using Apache Spark's ALS (alternating least squares) machine learning algorithm. We then walk through an example collaborative filtering web application for movie recommendations. The application is built using services on the IBM Cloud: Data Science Experience (DSX), Spark as a Service, Cloudant, Compose Redis and Bluemix. We briefly cover each of these services and the properties they bring to the application architecture.
Chris Snow is an IBM data and application architect who loves helping customers with their data architectures. He is currently focused on IBM Cloud Data Services and emerging technologies such as big data streaming architectures.
This session continues our education series of the mathematics underpinning machine learning algorithms. In this session we will do a quick refresher on basic probabilities and will cover Binary Logistic Regression. We will talk about the rules of probability and the Bernoulli distribution. We will derive the Logistic Regression model and we will look at techniques for estimating the model parameters. We will discuss certain principal assumptions of Logistic Regression, and we will see the model in action, and how it is typically used with a classification dataset.
