Sony patents method to fix bias in machine learning data
Sony describes a system that identifies unfair patterns in training data used for machine learning. It creates new, balanced data by adding noise to existing examples to help the model make fairer decisions.
In the filing’s own words
There is provided an information processing apparatus for artificially increasing data of a minority attribute to generate learning data for making fair determination on each piece of input data. The information processing apparatus includes a data holding unit configured to hold first learning data to be used for learning a machine learning model an acquisition unit configured to acquire information regarding bias of the learning data a data generation unit configured to generate second learning data by using data included in the learning data on the basis of the information regarding bias and a learning unit configured to learn the machine learning model by using the first learning data and the second learning data.
What exactly they claim (claim 1)
1. An information processing apparatus, comprising: circuitry configured to: hold first learning data for a learning operation of a machine learning model; acquire information regarding bias of the first learning data, wherein the acquired information regarding the bias corresponds to a set of data associated with at least one specific attribute, and the first learning data includes the set of data; superimpose noise on the first learning data; generate second learning data based on the superimposed noise on the first learning data and the information regarding the bias of the first learning data; and execute, based on the generated second learning data and the held first learning data, the learning operation of the machine learning model.
