Ethnicity Aware Training Datasets


INTRODUCTION


A major driver of bias in face recognition, as well as other AI tasks, is the training data. Deep face recognition networks are often trained on large-scale training datasets, such as CASIA-WebFace, VGGFace2 and MSCeleb-1M, which all contain racial bias. Thus, social awareness must be brought to the building of datasets for training. Here we provide four training datasets, i.e. BUPT-Balancedface, BUPT-Globalface, BUPT-Transferface and MS1M_wo_RFW, for studying facial bias and achieving fair performance.

The percentage of different races in commonly-used training datasets, BUPT-Globalface and BUPT-Balancedface dataset.




Ⅰ. BUPT-BALANCEDFACE


In order to remove this source of bias, we construct BUPT-Balancedface (Equalizedface) which contains 1.3M images from 28K celebrities and is approximately race-balanced with 7K identities per race. The images are selected from MS-Celeb-1M or directly downloaded from websites according to “Nationality” attribute of FreeBase celebrities or Face++ API.

Ⅱ. BUPT-GLOBALFACE

In existing training datasets, some race groups are over-represented and others are under-represented. In order to represent people of different regions equally, we construct BUPT-Globalface (Worldface) which contains 2M images from 38K celebrities in total. Its racial distribution is approximately the same as real distribution of world’s population.

Ⅲ. BUPT-TRANSFERFACE

Unsupervised domain adaptation (UDA) is one of the promising methodologies to address algorithm biases. Therefore, we provide a training dataset, i.e. BUPT-Transferface, under UDA setting for mitigating racial bias. We provide race label for each image but only provide identity label for Caucasians. You can use labeled images of Caucasians as source domain, and use unlabeled images of non-Caucasians as target domain.

•  For labeled data, each identity is named as '< freebaseID >' provided by freebase, e.g. 'm.0xnkj'. Each face image has unique name, e.g. 'm.0xnkj/m.0xnkj_00000.jpg' where 'm.0xnkj_00000.jpg' is named in a way '< identityID >_< faceID >.jpg'.

•  For unlabeled data, each face image also has unique name, e.g. 'asian/asian_00000.jpg' where 'asian_00000.jpg' is named in a way '< race >_< faceID >.jpg'.

Ⅳ. MS1M_WO_RFW

To develop fair technology across different races, we recommend using our testing dataset, i.e. RFW, to evaluate the face-recognition performance. However, there are overlaps between RFW and commonly used training dataset, i.e. MS-Celeb-1M, it is inconvenient to use it for training. So we remove their overlapping identities and release the remaining images of MS1M, i.e. MS1M_wo_RFW, for large-scale training. If you have the origin version of MS-Celeb-1M, you can directly select non-overlapping images from MS1M according to the index file, i.e. MS1M_wo_RFW_index.zip .
