Exponential priors for maximum entropy models
First Claim
1. A computer implemented method that maximizes probability values to facilitate training a machine learning system comprising:
- receiving a data set;
determining an Exponential distribution as a prior;
defining one or more parameters; and
training a model based at least in part upon a subset of the data set, the Exponential prior and the one or more parameters.

Abstract
The subject invention provides for systems and methods that facilitate optimizing one or mores sets of training data by utilizing an Exponential distribution as the prior on one or more parameters in connection with a maximum entropy (maxent) model to mitigate overfitting. Maxent is also known as logistic regression. More specifically, the systems and methods can facilitate optimizing probabilities that are assigned to the training data for later use in machine learning processes, for example. In practice, training data can be assigned their respective weights and then a probability distribution can be assigned to those weights.
