摘 要:在图像分类的实际应用场景中,受制于客观条件所以很难获取大规模的带标签数据集,针对缺少数据的场景,少样本学习得以广泛应用。然而现有少样本学习方法在图像处理时忽略了具有类别特点的局部细节对于分类的帮助,针对这一缺陷,对基于自适应局部细节增强(ALDR)注意力的少样本学习模型进行研究。实验证明,在 ALDR 注意力中通过对已学习数据提取的知识进行划分,利用不同种类的已学知识指导提取并增强新样例中具有类别特点的局部细节信息,在提升分类准确度上效果显著。

Abstract: In the actual application scenarios of image classification, it is difficult to obtain large-scale labeled datasets due to the objective conditions. For the scenes lacking data, small sample learning has been widely used. However, the existing few sample learning methods ignore the help of local details with category characteristics for classification in image processing. Aiming at this defect, the small sample learning model based on adaptive local detail enhancement (ALDR) attention is studied. The experiment proves that in ALDR attention, by dividing the knowledge extracted from the learned data and using different kinds of learned knowledge to guide the extraction and enhancement of local details with category characteristics in the new samples, the effect is significant in improving the classification accuracy.
Keywords: image classification; deep learning; ALDR attention; few sample learning
