Added machine learning endpoint for product search with images in Beta

The new Machine Learning API can queries a product catalog using an image. The endpoint returns images which are similar to the query image and the product variants they are associated with. This is a beta feature. For more information, see Beta Features.

A technical blog post about how the feature works can be read here.

The quality of predictions is highest when the product in the image is aligned centrally, with a noiseless background, and is taken in a similar style to that of images in the product database. The model has been benchmarked using fashion datasets, and so is optimized towards these kind of queries.

In the future, the Machine Learning team will develop these models further for more generalized accuracy.

• [API] Added public endpoints for the Image Search feature.
