Feature Selection from Unstructured Text Data Using Unsupervised Deep Learning


Feature Selection from Unstructured Text Data Using Unsupervised Deep Learning – Automatic diagnosis of Alzheimer’s disease (AD) and dementia remains a challenging problem due to large variation in the clinical and disease-specific data. In order to address this problem, large-scale datasets of neuroimaging data are required to deal with large-scale multi-label data. In this paper we focus on the task of image classification which is to identify the best images for a given task, when the training data are different. An efficient and tractable algorithm was developed to classify a task. This algorithm works on a class of images, and is applied to the classification task to avoid overfitting. The algorithm is evaluated using both simulated and real-world images taken from the same dataset. It is found to provide strong performance in classification tasks when used as an input for training the model. In an open-source MATLAB-based system we built a large dataset of real images. This dataset contains more than 70,000 images of different classifiers. We tested the proposed algorithm on several benchmark datasets. We find that the proposed approach outperforms existing unsupervised methods by a large margin on the most challenging data.

This paper presents a novel method for the detection of non-linear noise in a continuous background task. We construct a graph-space to model the background, and apply the method to solve a real-world problem in recommender system for automatic recommendation. The graph structures are derived using an alternating direction method of multiplicative and univariate analysis, and its similarity of the model structure to the input graph is estimated using a graph classifier. The graph classifier achieves performance at both classification and benchmark with the highest classification result. The graph classifier achieves a good performance for multi-output classification.
