Negative Margin Matters: Understanding Margin in Few-shot Classification
european conference on computer vision, pp. 438-455, 2020.
This paper introduces a negative margin loss to metric learning based few-shot learning methods. The negative margin loss significantly outperforms regular softmax loss, and achieves state-of-the-art accuracy on three standard few-shot classification benchmarks with few bells and whistles. These results are contrary to the common practice...More
