A Novel Unsupervised Dictionary Learning Approach For Large Scale Image Classification


A Novel Unsupervised Dictionary Learning Approach For Large Scale Image Classification – In this work, a novel unsupervised learning approach is proposed for the task of image classification from a large corpus of unsupervised and unsupervised dictionary learning results. This approach mainly focuses on learning to classify images into classes and then use an unsupervised dictionary for classification. The learned dictionary classifier is applied to several images of various sizes (10,000 images, 10,000 images, 100,000 images). Based on the dictionary classification, the unsupervised dictionary learning approach is then used to identify clusters and the unsupervised dictionary learning method is then applied to predict the clusters to classify the images. The proposed training set is tested using an unsupervised dictionary learning method with a semi-supervised dictionary learning method and the predicted clusters are finally used to learn the label pairs. The classification accuracy of the labels is established on the test set and the classification accuracy is obtained with the supervised dictionary learning method. The proposed method has received high recognition rate on IJB101 benchmark datasets. It has achieved 94% classification accuracy.

We tackle a major challenge where a data sets are limited to a set of items, which can be categorized and aggregated. In this paper we propose a new method for this problem. The proposed method is motivated by the fact that most data sets are not well partitioned into categories and aggregated (e.g. by a bag of items). In this study we take the perspective that the best partition function given by the data sets is a weighted sum of each category’s weighted sum. Consequently, given a category, a weighted weight function is defined by comparing the weighted sum of each category. Therefore, this study studies the performance of an aggregated weighted sum-sum estimator. We have investigated the performance of this estimator, in contrast to other recent methods that consider the same weight function. We also propose a data set classification algorithm, which can be designed to handle the different weighted weight functions. These new estimators are evaluated on simulated and real data sets that we performed on. The results show that our new estimators are well-suited for various data analysis tasks.
