How to load training data in MATlab?
To load the training and test data as image datastores, use the imageDatastore function. Specify the labels manually by extracting the labels from the file names and setting the Labels property. imdsTrain = imageDatastore(dataFolderTrain, ‘IncludeSubfolders’,true, ‘LabelSource’,’none’); files = imdsTrain.
Where can I find image datasets?
Google’s Open Images: Featuring a fantastic 9 million URLs, this is among the largest of the image datasets on this list that features millions of images annotated with labels across 6,000 categories. Columbia University Image Library: Featuring 100 unique objects from every angle within a 360 degree rotation.

What is a Matlab DataStore?
The datastore function creates a datastore, which is a repository for collections of data that are too large to fit in memory. A datastore allows you to read and process data stored in multiple files on a disk, a remote location, or a database as a single entity.
Is data store a database?
Datastore is a NoSQL document database built for automatic scaling, high performance, and ease of application development. Datastore features include: Atomic transactions. Datastore can execute a set of operations where either all succeed, or none occur.
