Google Prediction API: faster, easier to use, and more accurate

By Marc Cohen, Developer Relations

This holiday season, the Google Prediction API Team is bringing you four presents and, thanks to the joys of cloud computing, no reindeer are required for delivery. Here’s what you’ve already received:

• Faster on-ramp: We’ve made it easier to get started by enabling you to create an empty model (by sending a trainedmodels.insert request with no storageDataLocation specified) and add training data using the trainedmodels.update method. This change allows you to submit your model contents without needing to stage the data in Google Cloud Storage.
• Improved updates: The algorithms used to implement model updates (adding additional data to existing models) have been modified to work faster than ever.
• More classification algorithms: We’ve increased the number of classification algorithms used to build predictive models, resulting in across-the-board improvements in accuracy.
• Integration with Google Apps Script: Prediction services are now available as part of Google Apps Script, which means you can integrate prediction services with Google Docs, Google Maps, Gmail, and other great Google products.

All of the above enhancements are supported by the current Prediction API version 1.4 so you can enjoy these features using the existing client libraries.

Happy Holidays from the Google Prediction API Team. We’re looking forward to bringing you more exciting features in 2012!
