WebApr 13, 2024 · The meaning of IN BATCHES is in small quantities at a time. How to use in batches in a sentence. WebThe advantage of the bi-encoder teacher–student setup is that we can efficiently add in-batch negatives during knowledge distillation, enabling richer interactions between teacher and student models. In addition, using ColBERT as the teacher reduces training cost compared to a full cross-encoder.
