5. The method of claim 4 , further comprising: receiving a predictive query or a latent structure query requesting a result from the indices generated by processing the dataset; and executing the query against the generated indices prior to terminating processing of the dataset.
4. The method of claim 1 , wherein: processing the dataset to generate indices comprises iteratively learning joint probability distributions over the dataset to generate the indices; and wherein the method further comprises: periodically determining a confidence quality measure of the indices generated by the processing of the dataset; and terminating processing of the dataset when the confidence quality measure attains a specified threshold.
