Clustering-Based Representation Learning through Output Translation and Its Application to Remote-Sensing Images

چکیده

In supervised deep learning, learning good representations for remote-sensing images (RSI) relies on manual annotations. However, in the area of remote sensing, it is hard to obtain huge amounts labeled data. Recently, self-supervised shows its outstanding capability learn images, especially methods instance discrimination. Comparing discrimination, clustering-based not only view transformations same image as “positive” samples but also similar images. this paper, we propose a new method representation learning. We first introduce quantity measure representations’ discriminativeness and from which show that even distribution requires most discriminative representations. This provides theoretical insight into why evenly distributing works well. notice distributions preserve neighborhood relations are desirable. Therefore, develop an algorithm translates outputs neural network achieve goal while preserving outputs’ relations. Extensive experiments have demonstrated our can or better than state art approaches, performs computationally efficiently robustly various RSI datasets.

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...

Tensor Representation and Manifold Learning Methods for Remote Sensing Images

One of the main purposes of earth observation is to extract interested information and knowledge from remote sensing (RS) images with high efficiency and accuracy. However, with the development of RS technologies, RS system provide images with higher spatial and temporal resolution and more spectral channels than before, and it is inefficient and almost impossible to manually interpret these im...

Objects localization in remote sensing images using local features clustering

There is an increasing trend towards object detection from aerial and satellite images. Most of the recent state-of the-art widely used object detection researches based on local features use the scanning of images by the sliding window. In this paper we propose an approach to localize the candidate objects by using the clustering of locations of the matched keypoints, this method has a benefit...
