1. A system for data classification and identification, the system comprising:
- a database of training objects, the database comprising a storage medium populated with stored computer records specifying, for each of a plurality of training objects, psychometric data pertaining thereto;
a computer processor;
a classification device for receiving query objects different from the training objects;
a penalization module, executable by the computer processor, for deriving a human-weighted loss function based at least in part on the psychometric data, the loss function comprising penalties for misclassification, magnitudes of the penalties increasing with increasing deviation from the classification data; and
a classification module, executable by the computer processor, for classifying features of query objects based at least in part on the human-weighted loss function.

Abstract
In various embodiments, training objects are classified by human annotators, psychometric data characterizing the annotation of the training objects is acquired, a human-weighted loss function based at least in part on the classification data and the psychometric data is computationally derived, and one or more features of a query object are computationally classified based at least in part on the human-weighted loss function.
