- 4. #BuildingWithWatso n Our Goals • In this series, we want to focus on the Watson services that allow you to customize functionality to better fit your use case and industry • Today, we'll be showing you our Visual Recognition service, which includes an option for custom image classifiers © 2015 International Business Machines Corporation
- 5. #BuildingWithWatso n Haven't we seen this before? • We've covered image recognition services before, but never like this! • Our May 18th webinar showed you how to add basic image tagging to a BI dashboard using the built-in classifiers offered by Visual Recognition • Today we'll be diving in deeper to show you exactly what is needed to train a custom image classifier © 2015 International Business Machines Corporation
- 6. #BuildingWithWatso n Think of yourself as Watson Vision’s Coach • Provide example training images that are similar to the images you plan to analyze • If training the classifier "tiger", might be less accurate if you provide only images of tigers in a zoo taken by a mobile phone if you want to test the classifier on images of tigers in the wild taken by professional photographers.
- 7. #BuildingWithWatso n More guidelines for good training • If the quality and content of training data is the same, then classifiers that are trained on more images will generally be more accurate • The benefits of more images plateaus ~5000 images • Recommend 150-200 images per .zip file for good balance between training time and improvement to accuracy
- 8. #BuildingWithWatso n Guidelines for high volume custom classifying• Include approximately the same number of images in each examples file • Resize images to be no larger than 320 pixels in either width or height. Images do not need to be high resolution. • Submit images in batches as compressed (.zip) files. • Parallelize by groups of images, not groups of classifiers • Specify only the classifiers you want results for in the classifier_ids parameter.
