This book was released on 2015 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Text classification is one of the classical problems in computer science, which is primarily used for categorizing data, spam detection, anonymization, information extraction, text summarization etc. Given the large amounts of data involved in the above applications, automated and accurate training models and approaches to classify data efficiently are needed. In this thesis, an extensive study of the interaction between natural language processing, information retrieval and text classification has been performed. A case study named "keyword extraction" that deals with 'identifying keywords and tags from millions of text questions' is used as a reference. Different classifiers are implemented using MapReduce paradigm on the case study and the experimental results are recorded using two newly built distributed computing Hadoop clusters. The main aim is to enhance the prediction accuracy, to examine the role of text pre-processing for noise elimination and to reduce the computation time and resource utilization on the clusters.

This book was released on 2021 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Networking and distributed computing system have provided computational resources for machine learning (ML) application for a long time. Network system itself also can benefit from ML technologies. For example high performance packet classification is a key component to support scalable network applications like firewalls, intrusion detection, and differentiated services. With ever increasing demand in the line rate for core networks, a great challenge is to use hand-tuned heuristic approaches to design a scalable and high performance packet classification solution. By exploiting the sparsity present in a ruleset, in this thesis an algorithm is proposed to use few effective bits (EBs) to extract a large number of candidate rules with just a few number of memory access. These effective bits are learned with deep reinforcement learning and they are used to create a bitmap to filter out the majority of rules which do not need to be fully matched to improve the online system performance. Utilizing reinforcement learning allows the proposed solution to be learning based rather than heuristic based algorithms. So proposed learning-based selection method is independent of the ruleset, which can be applied to different rulesets without relying on the heuristics. Proposed multibit tries classification engine outperforms lookup time both in worst and average case by 55% and reduce memory footprint, compared to traditional decision tree without EBs. Furthermore, many field packet classification are required for openFlow supported switches. With the proliferation of fields in the packet header, a traditional 5-field classification technique isn't applicable for an efficient classification engine for those openFlow supported switches. Although the algorithmic insights obtained from 5-field classification techniques could still be applied for many field classification engine. To decompose given fields of a ruleset, different grouping metrics like standard deviation of individual fields and a novel metric called Diversity Index (DI) is considered for such many field scenarios. A detailed discussion and evaluation of how to decompose rule fields/dimension into subgroup, how a decision tree construction can be considered as reinforcement learning problem, and how to encode state and action space, reward calculation to effectively build trees for each subgroup with a global optimization objective is introduced in this work. Finally, to identify benign or malicious heterogeneous type of traffic present in a modern home network, a deep neural network based approach is introduced. A split architecture of such traffic classifier, in application of home network intrusion detection system consists of multiple machine learning (ML) models. These models trained on two separate dataset for heterogeneous traffic types. An analysis of run-time implementation performance of the proposed IDS models is also discussed.

This book was released on 2009-11-13 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Text classification is becoming a crucial task to analysts in different areas. In the last few decades, the production of textual documents in digital form has increased exponentially. Their applications range from web pages to scientific documents, including emails, news and books. Despite the widespread use of digital texts, handling them is inherently difficult - the large amount of data necessary to represent them and the subjectivity of classification complicate matters. This book gives a concise view on how to use kernel approaches for inductive inference in large scale text classification; it presents a series of new techniques to enhance, scale and distribute text classification tasks. It is not intended to be a comprehensive survey of the state-of-the-art of the whole field of text classification. Its purpose is less ambitious and more practical: to explain and illustrate some of the important methods used in this field, in particular kernel approaches and techniques.

Download or read book SigsSpace Text written by Rakesh Reddy Bandi and published by . This book was released on 2016 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Big data analytics uncover hidden patterns and useful information from big data. It is a complex and time-consuming process. Recent advancements in parallel and distributed approaches have led to the evolution of big data analytics. It also claimed bigger data may not always be better data. Toward scalable solutions for big data analytics, it is highly demanded to have a scalable and dynamic process with more representative and relevant sets of data. We envision that if the condensed and representative sample can be drawn from very large-scale datasets in a parallel and distributed manner and this can be defined as signature learning, this approach can provide more accurate results in an efficient manner. Using signature learning with relevant datasets in a parallel and distributed manner, the complexity of big data problems can be reduced. In this thesis, we propose the SigSpace-Text framework that is an extension of our previous model of signature-based learning (SigSpace) that proved the effectiveness of signature-based classification with image signatures and audio signatures. SigSpace was not feasible with text data due to the inherent problems in the text domain such as a high-dimensional feature space and sparse feature vectors. In order to handle these issues, we explore using Natural Language Processing, that features extraction and feature selection techniques (TFIDF, Word2Vec). Signature learning in SigSpace-Text is based on a class-level clustering approach, in which a generic pattern is identified for a given category using state-of-the-art clustering algorithms, i.e., K-Means, Self-Organizing Maps (SOM), and Gaussian Mixture Models (GMM). These signatures are used (instead of raw data) as a feature set to the classification. Through extension, the proposed SigSpace-Text approach brings vital, practical information to signature learning approaches on several text classification tasks. The SigSpace-Text model supports incremental, distributed, and parallel learning using big data analytics including Apache Spark and the Machine Learning library such as Spark MLlib. In experiments with the SigSpace-Text framework, the effectiveness of the proposed signature learning model was evaluated for various parameters (such as the signature size, classification algorithms, local signatures/global signatures) and was also validated with a number of classification algorithms (i.e., Naïve Bayes, Decision Trees, and Random Forests) using 20 newsgroup dataset. Based on these observations, we identify that SigSpace-Text outperforms state-of-the-art performance results on the dataset.
