Exploring Vowpal Wabbit with the Avazu Clickthrough Prediction Challenge

In online advertising, click-through rate (CTR) is a very important metric for evaluating ad performance. As a result, click prediction systems are essential and widely used for sponsored search and real-time bidding.

For this competition, we have provided 11 days worth of Avazu data to build and test prediction models. Can you find a strategy that beats standard classification algorithms? The winning models from this competition will be released under an open-source license.

Data Fields

Project Idea: Machine Learning + Cricket

One of the most prominent field of application of machine learning in sports, and a lot of people love sports statistics. It is an excellent domain for practicing data exploration and visualization. In fact, most machine learning work that perform well on sports data is 90% data exploration and 10% model building.

Cricsheet has a bunch of cricket data available for download.

We provide ball-by-ball data for Men’s and Women’s T...

Yes you should try multiple models, and try to reason which one is performing better on this particular dataset and why. This includes SVM, logistic regression, K nearest neighbors, etc

I constructed the dataset using WordNet. The problem is that the dataset will have a lot of false negatives. For example, a camel is a herbivore, but that connection might be missing in WordNet.

Machine Learning for Autonomous Path Planning

I am attempting to make a ground based robot traverse from Point A to Point B through an Obstacle Course having fixed and moving obstacles (Imagine a marketplace or a railway station), with input from a camera feed (a group of CCTV cameras/ live feed from a drone over the area). What kind of ML algorithm will enable the system to plan the shortest path(s) for the ground robot to follow under varying circumstances (moving obstacles at certain speeds travelling randomly over the task plane)?

You'd could use something like A* search (which is an algorithm, nothing to do with machine learning). However, you could use reinforcement learning techniques in figuring out when to explore,...
