چکیده انگلیسی
Convolutional neural networks (CNNs) have become state-of-the-art for image classification. Inspired by the physiological mechanism of saliency in real human visual system (HVS), we had previously proposed the Sal-Mask Connection. As HVS tends to select specified region of the visual field depending on saliency to interpret complex scenes, we use saliency data as an element-by-element mask on feature maps learned from convolutional connections. The effectiveness of the Sal-Mask Connection had been verified in our previous work. However, as the performance of Sal-Mask Connection was influenced by the saliency data used, and current saliency algorithms are not designed to work for image classification, it is urgent and essential that we obtain a more suitable saliency. In this paper, therefore, we propose Ada-Sal Network to learn saliency adaptively while feature maps are being trained at the same time. Experiments on CIFAR-10 and STL-10 datasets are done with three various networks. In each test, we compare the performance of benchmark network, Sal-Mask Networks using two different saliencies, with that of the Ada-Sal Network. The results indicate that Ada-Sal Network outperforms not only traditional networks but also Sal-Mask Network using non-adaptive saliency. Visualization of the networks exhibits the saliency learned adaptively is able to combine merits from input saliencies and seems to work better for most cases.
