Fine-Grained Visual Classification (FGVC) datasets contain small sample sizes, along with significant intra-class variation and interclass similarity. ...
This procedure, called Pairwise Confusion (PC) attempts to learn features with greater generalization, thereby preventing overfitting. ...
To do so, we propose Pairwise Confusion (PC), a pairwise algorithm for training convolutional neural networks (CNNs) end-to-end for fine-grained visual classification. ...

In this paper, we explore to excavate the confusion matrix, which carries the fine-grained misclassification details, to relieve the pairwise biases, generalizing the coarse one. ...
To this end, we propose a novel Pairwise Class Balance (PCB) method, built upon a confusion matrix which is updated during training to accumulate the ongoing prediction preferences. ...
So we take one step further, a two-dimensional statistics (i.e., confusion matrix) is utilized to indicate fine-grained pairwise bias. Confusion Matrix. ...

Vegetable and fruit recognition can be considered as a fine-grained visual categorization (FGVC) task, which is challenging due to the large intraclass variances and small interclass variances. ...
Inspired by this intuition, a recent FGVC method, named Attentive Pairwise Interaction Network (API-Net), takes as input an image pair for pairwise feature interaction and demonstrates superior performance ...
In contrast, humans often recognize fine-grained objects by comparing image pairs to extract subtle visual differences that can be used as distinguishable features. ...
