Geoseq2seq: Information Geometric Sequence-To-Sequence Networks
GEOSEQ2SEQ:INFORMATION GEOMETRIC SEQUENCE-TO-SEQUENCE NETWORKS Alessandro Bay Biswa Sengupta Cortexica Vision Systems Ltd. Noah’s Ark Lab (Huawei Technologies UK) London, UK Imperial College London, London, UK [email protected] ABSTRACT The Fisher information metric is an important foundation of information geometry, wherein it allows us to approximate the local geometry of a probability distribu- tion. Recurrent neural networks such as the Sequence-to-Sequence (Seq2Seq) networks that have lately been used to yield state-of-the-art performance on speech translation or image captioning have so far ignored the geometry of the latent embedding, that they iteratively learn. We propose the information geometric Seq2Seq (GeoSeq2Seq) network which abridges the gap between deep recurrent neural networks and information geometry. Specifically, the latent embedding offered by a recurrent network is encoded as a Fisher kernel of a parametric Gaus- sian Mixture Model, a formalism common in computer vision. We utilise such a network to predict the shortest routes between two nodes of a graph by learning the adjacency matrix using the GeoSeq2Seq formalism; our results show that for such a problem the probabilistic representation of the latent embedding supersedes the non-probabilistic embedding by 10-15%. 1 INTRODUCTION Information geometry situates itself in the intersection of probability theory and differential geometry, wherein it has found utility in understanding the geometry of a wide variety of probability models (Amari & Nagaoka, 2000). By virtue of Cencov’s characterisation theorem, the metric on such probability manifolds is described by a unique kernel known as the Fisher information metric. In statistics, the Fisher information is simply the variance of the score function. -
Data Mining and Soft Computing

Web: www.witpress.com Email [email protected] Paper from: Data Mining III, A Zanasi, CA Brebbia, NFF Ebecken & P Melli (Editors). ISBN 1-85312-925-9 Data mining and soft computing O. Ciftcioglu Faculty of Architecture, Deljl University of Technology Delft, The Netherlands Abstract The term data mining refers to information elicitation. On the other hand, soft computing deals with information processing. If these two key properties can be combined in a constructive way, then this formation can effectively be used for knowledge discovery in large databases. Referring to this synergetic combination, the basic merits of data mining and soft computing paradigms are pointed out and novel data mining implementation coupled to a soft computing approach for knowledge discovery is presented. Knowledge modeling by machine learning together with the computer experiments is described and the effectiveness of the machine learning approach employed is demonstrated. 1 Introduction Although the concept of data mining can be defined in several ways, it is clear enough to understand that it is related to information extraction especially in large databases. The methods of data mining are essentially borrowed from exact sciences among which statistics play the essential role. By contrast, soft computing is essentially used for information processing by employing methods, which are capable to deal with imprecision and uncertainty especially needed in ill-defined problem areas. In the former case, the outcomes are exact within the error bounds estimated. In the latter, the outcomes are approximate and in some cases they may be interpreted as outcomes from an intelligent behavior. -

Challenges in Bioinformatics for Statistical Data Miners
This article appeared in the October 2003 issue of the “Bulletin of the Swiss Statistical Society” (46; 10-17), and is reprinted by permission from its editor. Challenges in Bioinformatics for Statistical Data Miners Dr. Diego Kuonen Statoo Consulting, PSE-B, 1015 Lausanne 15, Switzerland [email protected] Abstract Starting with possible definitions of statistical data mining and bioinformatics, this article will give a general side-by-side view of both fields, emphasising on the statistical data mining part and its techniques, illustrate possible synergies and discuss how statistical data miners may collaborate in bioinformatics’ challenges in order to unlock the secrets of the cell. What is statistics and why is it needed? Statistics is the science of “learning from data”. It includes everything from planning for the collection of data and subsequent data management to end-of-the-line activities, such as drawing inferences from numerical facts called data and presentation of results. Statistics is concerned with one of the most basic of human needs: the need to find out more about the world and how it operates in face of variation and uncertainty. Because of the increasing use of statistics, it has become very important to understand and practise statistical thinking. Or, in the words of H. G. Wells: “Statistical thinking will one day be as necessary for efficient citizenship as the ability to read and write”. But, why is statistics needed? Knowledge is what we know. Information is the communication of knowledge. Data are known to be crude information and not knowledge by itself. The way leading from data to knowledge is as follows: from data to information (data become information when they become relevant to the decision problem); from information to facts (information becomes facts when the data can support it); and finally, from facts to knowledge (facts become knowledge when they are used in the successful completion of the decision process). -

Juang [5] proposed the CQGAF to (TNFS) with reinforcement learning for data mining based simultaneously design the number of fuzzy rules and free evolution algorithm (R-DMEA). In R-DMEA, the group-based parameters in a fuzzy system. In [6], the group-based symbiotic symbiotic evolution (GSE) is adopted that each group represents evolution (GSE) was proposed to solve the problem that all the the set of single fuzzy rule. The R-DMEA contains both fuzzy rules were encoded into one chromosome in the structure learning and parameter learning. In the structure traditional genetic algorithm. In the GSE, each chromosome learning, the proposed R-DMEA uses the two-step self-adaptive represents a single rule of fuzzy system. The GSE uses algorithm to decide the suitable number of rules in a TNFS. In group-based population to evaluate the fuzzy rule locally. parameter learning, the R-DMEA uses the mining-based Although GSE has a better performance when compared with selection strategy to decide the selected groups in GSE by the tradition symbiotic evolution, the combination of groups is data mining method called frequent pattern growth.

Data Management, Analysis Tools, and Analysis Mechanics
Chapter 2 Data Management, Analysis Tools, and Analysis Mechanics This chapter explores different tools and techniques for handling data for research purposes. This chapter assumes that a research problem statement has been formulated, research hypotheses have been stated, data collection planning has been conducted, and data have been collected from various sources (see Volume I for information and details on these phases of research). This chapter discusses how to combine and manage data streams, and how to use data management tools to produce analytical results that are error free and reproducible, once useful data have been obtained to accomplish the overall research goals and objectives. Purpose of Data Management Proper data handling and management is crucial to the success and reproducibility of a statistical analysis. Selection of the appropriate tools and efficient use of these tools can save the researcher numerous hours, and allow other researchers to leverage the products of their work. In addition, as the size of databases in transportation continue to grow, it is becoming increasingly important to invest resources into the management of these data. There are a number of ancillary steps that need to be performed both before and after statistical analysis of data. For example, a database composed of different data streams needs to be matched and integrated into a single database for analysis. In addition, in some cases data must be transformed into the preferred electronic format for a variety of statistical packages. Sometimes, data obtained from “the field” must be cleaned and debugged for input and measurement errors, and reformatted. The following sections discuss considerations for developing an overall data collection, handling, and management plan, and tools necessary for successful implementation of that plan. -
