common variable immunodeficiency (cvid) is a heterogeneous heritable disease characterized by arrest in b cell differentiation. an association between cvid and two hla haplotypes, haplotype i (hla-a1, hla-b8, hla-dr3) and haplotype ii (hla-a29, hla-b44, hladr7)has been previously documented. in the present study, we have attempted to find an association between susceptibility to cvid and hla cl...

In this paper we report the contribution of XRCE team to the Domain Adaptation Challenge [10] organized in the framework of ImageCLEF 2014 competition [9]. We describe our approach to build an image classification system when a weak image annotation in the target domain is compensated by massively annotated images in source domains. One method is based using several heterogeneous methods for th...

Incorrectly labeled examples, or label noise, is common in real-world computer vision datasets. While the impact of noise on learning deep neural networks has been studied prior work, these studies have exclusively focused homogeneous i.e., degree same across all categories. However, real-world, often heterogeneous, with some categories being affected to a greater extent than others. Here, we a...
