Training a neural network model across multiple domains

Abstract

The disclosure relates to systems and methods of generating a mixture model for approximating non-normal distributions of time series data. The mixture model may include clusters of normal distributions that together approximate a non-normal distribution. The mixture model may be used to normalize input data for machine learning models. For example, a machine learning model such as an autoencoder may be trained to make predictions on the normalized input data. The predictions may relate to the time series of data. In one example, the time series of data may be market data for a security. The market data my include one or more features that are normalized using the mixture model. The predictions may include a predicted rate at which a lender will charge to borrow a security for short selling, where such rate may depend on the market data for the security.
