Patent number: 11204973Abstract: In an example embodiment, position bias and other types of bias may be compensated for by using two-phase training of a machine-learned model. In a first phase, the machine-learned model is trained using non-randomized training data. Since certain types of machine-learned models, such as those involving deep learning (e.g., neural networks) require a lot of training data, this allows the bulk of the training to be devoted to training using non-randomized training data. However, since this non-randomized training data may be biased, a second training phase is then used to revise the machine-learned model based on randomized training data to remove the bias from the machine-learned model. Since this randomized training data may be less plentiful, this allows the deep learning machine-learned model to be trained to operate in an unbiased manner without the need to generate additional randomized training data.Type: GrantFiled: June 21, 2019Date of Patent: December 21, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Daniel Sairom Krishnan Hewlett, Dan Liu, Qi Guo, Wenxiang Chen, Xiaoyi Zhang, Lester Gilbert Cottle, III, Xuebin Yan, Yu Gong, Haitong Tian, Siyao Sun, Pei-Lun Liao
