Generating compressed representation neural networks having high degree of accuracy

Abstract

Machine learning based models, for example, neural network models employ large numbers of parameters, from a few million to hundreds of millions or more. A machine learning based model is trained using fewer parameters than specified. An initial parameter vector is initialized, for example, using random number generation based on a seed. During training phase, the parameter vectors are modified in a subspace around the initial vector. The trained model can be stored or transmitted using seed values and the trained parameter vector in the subspace. The neural network model can be uncompressed using the seed values and the trained parameter vector in the subspace. The compressed representation of neural networks may be used for various applications such as generating maps, object recognition in images, processing of sensor data, natural language processing, and others.
