Abstract
The system receives a base machine learning model trained using a generic dataset. For example, the base machine learning model may be an off-the-shelf machine learning based model. The base machine learning model is trained to receive an input and generate a feature vector representing the input. The input may be a natural language expression, an image, or any other type of input. The system receives a domain specific training dataset based on known categories for input values. The system determines an orthogonal transformation for reducing the dimensions of the base machine learning model using on the domain specific training dataset. The system applies the orthogonal transformation to the base machine learning model to obtain a domain specific machine learning model. The system uses the domain specific machine learning model for processing inputs, for example, in a production environment.
