Abstract: Methods, systems, and computer program products are provided for embedding learning to provide uniformity and orthogonality of embeddings. A method may include receiving a dataset that includes a plurality of data points including a first plurality of data points having a first classification and a second plurality of data points having a second classification, generating a first normalized class mean vector of the first plurality of data instances having the first classification, generating a second normalized class mean vector of the second plurality of data instances having the second classification, performing a class rectification operation on the first plurality of data instances having the first classification and the second plurality of data instances having a second classification, and generating embeddings of the dataset based on original embedding space projections of the dataset.
