This video is part of the Segment on Statistical Data Analysis in a series on RapidMiner Studio. The video demonstrates how to use an aggregate operator to derive various statistics, such as mean, median, mode or standard deviation from a data sample, for both numerical and nominal attributes. It is explained how to group aggregates by a nominal attribute and thus produce the relevant statistics for each of the nominal attribute levels (possible values). Most importantly, the aggregate operator return all statistics in the form of data examples, which means they can be used by other operators as input to further processing. As several aggregates are produced in the course of this video, it is also shown how to create many copies of the same data set using a multiply operator.

Lu Chen's Dissertation Defense: " Mining and Analyzing Subjective Experiences in User Generated Content " Tuesday, August 9, 2016 Dissertation Committee: Dr. Amit Sheth, Advisor, Dr. T. K. Prasad, Dr. Keke Chen, Dr. Ingmar Weber, and Dr. Justin Martineau Home Page: http://knoesis.org/researchers/luchen/ Pictures: https://www.facebook.com/Kno.e.sis/photos/?tab=album&album_id=1225911137443732 Slides: https://www.slideshare.net/knoesis/mining-and-analyzing-subjective-experiences-in-usergenerated-content ABSTRACT: Web 2.0 and social media enable people to create, share and discover information instantly anywhere, anytime. A great amount of this information is subjective information -- the information about people's subjective experiences, ranging from feelings of what is happening in our daily lives to opinions on a wide variety of topics. Subjective information is useful to individuals, businesses, and government agencies to support decision making in areas such as product purchase, marketing strategy, and policy making. However, much useful subjective information is buried in ever-growing user generated data on social media platforms, it is still difficult to extract high quality subjective information and make full use of it with current technologies. Current subjectivity and sentiment analysis research has largely focused on classifying the text polarity -- whether the expressed opinion regarding a specific topic in a given text is positive, negative, or neutral. This narrow definition does not take into account the other types of subjective information such as emotion, intent, and preference, which may prevent their exploitation from reaching its full potential. This dissertation extends the definition and introduces a unified framework for mining and analyzing diverse types of subjective information. We have identified four components of a subjective experience: an individual who holds it, a target that elicits it (e.g., a movie, or an event), a set of expressions that describe it (e.g., "excellent", "exciting"), and a classification or assessment that characterize it (e.g., positive vs. negative). Accordingly, this dissertation makes contributions in developing novel and general techniques for the tasks of identifying and extracting these components. We first explore the task of extracting sentiment expressions from social media posts. We propose an optimization-based approach that extracts a diverse set of sentiment-bearing expressions, including formal and slang words/phrases, for a given target from an unlabeled corpus. Instead of associating the overall sentiment with a given text, this method assesses the more fine-grained target-dependent polarity of each sentiment expression. Unlike pattern-based approaches which often fail to capture the diversity of sentiment expressions due to the informal nature of language usage and writing style in social media posts, the proposed approach is capable of identifying sentiment phrases of different lengths and slang expressions including abbreviations and spelling variations. We then look into the task of finding opinion targets in product reviews, where the product features (product attributes and components) are usually the targets of opinions. We propose a clustering approach that identifies product features and groups them into aspect categories. Finally, we study the classification and assessment of several types of subjective information (e.g., sentiment, political preference, subjective well-being) in two specific application scenarios. One application is to predict election results based on analyzing the sentiments of social media users towards election candidates. Observing that different political preference and tweeting behavior of users may have significant effect on predicting election results. We propose methods to group users based on their political preference and participation in the discussion, and assess their sentiments towards the candidates to predict the results. We examine the predictive power of different user groups in predicting the results of 2012 U.S. Republican Presidential Primaries. The other application is to understand the relationship between religiosity and subjective well-being (or happiness). We analyze the tweets and networks of more than 250k U.S. Twitter users who self-declared their beliefs. We build classifiers to classify believers of different religions using the self-declared data. In order to understand the effect of religiosity on happiness, we examine the pleasant/unpleasant emotional expressions in users' tweets to estimate their subjective well-being, and investigate the variations in happiness among religious groups.

What do you do with a library? The large-scale digital collections scanned by Google and the Internet Archive have opened new ways to interact with books. The scale of digitization, however, also presents a challenge. We must find methods that are powerful enough to model the complexity of culture, but simple enough to scale to millions of books. In this talk I'll discuss one method, statistical topic modeling. I'll begin with an overview of the method. I will then demonstrate how to use such a model to measure changes over time and distinctions between sub-corpora. Finally, I will describe hypothesis tests that help us to distinguish consistent patterns from random variations.

In this episode, our resident RapidMiner masterminds, Ingo Mierswa & Simon Fischer, spend some quality time together building a cross validation process on Fisher’s Iris data set (name pun intended). Seeing as Ingo had recently talked about cross-validation, today he and Simon quickly design the complete process and discuss what this important method looks like in practice. Simon then jumps in and gives a guest lecture on a so-called "error matrix" and together the boys cover key performance metrics including precision, recall, and accuracy. At that point, they realize how much coding effort originally went into this series of implementations which leads to Ingo's strange daydream about Code Club. But we're not to supposed to talk about that. Plus, Data Scientist #7 asks "where is my mind" as he reads Prolog by Hans Kleine Büning & Stefan Schmitgen.

Full Title: I can do text analytics!: designing development tools for novice developers Authors: Huahai Yang, Daina Pupons-Wickham, Laura Chiticariu, Yunyao Li, Benjamin Nguyen, Arnaldo Carreno-Fuentes Abstract: Text analytics, an increasingly important application domain, is hampered by the high barrier to entry due to the many conceptual difficulties novice developers encounter. This work addresses the problem by developing a tool to guide novice developers to adopt the best practices employed by expert developers in text analytics and to quickly harness the full power of the underlying system. Taking a user centered task analytical approach, the tool development went through multiple design iterations and evaluation cycles. In the latest evaluation, we found that our tool enables novice developers to develop high quality extractors on par with the state of art within a few hours and with minimal training. Finally, we discuss our experience and lessons learned in the context of designing user interfaces to reduce the barriers to entry into complex domains of expertise.

Speaker: Chen Li Title / Affiliation: Professor, School of Information and Computer Sciences University of California, Irvine Talk Abstract: We are developing an open source system called "TextDB" for text analytics on large data sets. The goal is to build a text-centric data-management system to enable declarative and scalable query processing. It supports common text computation as operators, such as keyword search, dictionary-based matching, similarity search, regular expressions, and natural language processing. It supports index-based operators without scanning all the documents one by one. These operators can be used to compose more complicated query plans to do advanced text analytics. In the talk we will give an overview of the system, and present details about these operators and query plans. We will also report our initial results of using the system to do information extraction. The system is available at https://github.com/TextDB/textdb/wiki Biography: Chen Li is a professor in the Department of Computer Science at the University of California, Irvine. He received his Ph.D. degree in Computer Science from Stanford University in 2001, and his M.S. and B.S. in Computer Science from Tsinghua University, China, in 1996 and 1994, respectively. His research interests are in the field of data management, including data cleaning, data integration, data-intensive computing and text analytics. He was a recipient of an NSF CAREER Award, several test-of-time publication awards, and many other grants and industry gifts. He was once a part-time Visiting Research Scientist at Google. He founded a company SRCH2 to develop an open source search engine with high performance and advanced features from ground up using C++.

Welcome to Demo on Sentiment Analysis using Operator's Social Media Data Background & Purpose The purpose of the application is to analyze the customer sentiment (positive, neutral or negative) towards the services of two major Indian Operators -- Vodafone & Airtel. The application makes use of social media data of these Telco's for Analysis. Operators use social media platform as a promotional channel to increase awareness of their products and services and also, to address complaints of customers. Customer comes to these Facebook and Twitter pages to highlight any problems they are facing with the service. Since, social media posts have a high chance of going viral through re-post and re-tweets, hence a dedicated team is assigned to analyze all posts so as to resolve the customer complaints in a timely manner. The application would be of help to operators to do a comparative analysis of how their service is perceived by customer w.r.t to that of their competitors and draw actionable insights of the areas where they need to focus on. For example, geographical areas where they need to improve their network revise existing rate plans or offer new products. Data The data in the application is scrapped from Twitter and Facebook pages of Vodafone and Airtel. Analytical tool 'R' is then used to process this data to identify the sentiment of post/tweet and determine the category of the post such as Rate Plan, Billing, Network etc. Processed data is downloaded in form of an xls and used by MicroStartegy Analytic Desktop for Analysis (open xls attachments). Metrics like 'City' from where post was made, Number of followers, Page Rank of the posters are also captured. Analysis I shall now walk you through each of the dashboards(twitter, facebook) and describe the various visualizations. There are principally two dashboards in the application that provides ability to do analysis on Vodafone and Airtel social media by criteria such as - • Location • Influencer • Post Category I hope you have enjoyed Sentiment Analysis of Operator's Social media data. Thank you for taking time to watch this demo. Please also have a look at some of other demos as well.

Dr. Sanda Harabagiu from University of Texas at Dallas presents a lecture on "Data Wrangling, Normalization & Preprocessing: Part II Text." Lecture Abstract Data wrangling is defined as the process of mapping data from an unstructured format to another format that enables automated processing. State of the art deep learning systems require vast amounts of annotated data to achieve high performance, and hence, this is often referred to as a Big Data problem. Many decision support systems in healthcare can be successfully automated if such big data resources existed. Therefore, automated data wrangling is crucial to the application of deep learning to healthcare. In this talk, we will discuss data wrangling challenges for physiological signals commonly found in healthcare, such as electroencephalography (EEG) signals. For signal and image data to be useful in the development of machine learning systems, identification and localization of events in time and/or space plays an important role. Normalization of data with respect to annotation standards, recording environments, equipment manufacturers and even standards for clinical practice, must be accomplished for technology to be clinically relevant. We will specifically discuss our experiences in the development of a large clinical corpus of EEG data, the annotation of key events for which there is low inter-rater agreement (such as seizures), and the development of technology that can mitigate the variability found in such clinical data resources. In a companion talk to be given on December 2, data wrangling of unstructured text, such as that found in electronic medical records, will be discussed.

Retention modeling for higher education can be quite challenging in the best of conditions. However, predicting who will retain and who will not can be even more difficult if your school is relatively small and has a relatively high retention rate. Couple this condition with the very dynamic environment we are currently experiencing in higher education and you have an even more demanding task. In this presentation, Dr. Johnson, Director of Institutional Research at Dickinson College, provides details for the methodology used by Dickinson College to create a first-year retention model using Rapid Insight Analytics software. The results are discussed to some degree, highlighting the fact that sometimes what you don't find in the model can be almost as useful as what you do.

Deep Dhillon, CTO of Evri.com presents Evri's technology to UW students at the Paul G. Allen Center for Computer Science & Engineering. Talk abstract: Unstructured natural language text found in blogs, news and other web content is rich with semantic relations linking entities (people, places and things). At Evri, we are building a system which automatically reads web content similar to the way humans do. The system can be thought of as an army of 7th grade grammar students armed with a really large dictionary. The dictionary, or knowledge base, consists of relatively static information mined from structured and semi-structured publicly available information repositories like Freebase, Wikipedia, and Amazon. This large knowledge base is in turn used by a highly distributed search and indexing infrastructure to perform a deep linguistic analysis of many millions of documents ultimately culminating in a large set of semantic relationships expressing grammatical SVO style clause level relationships. This highly expressive, exacting, and scalable index makes possible a new generation of content discovery applications. Need a custom machine learning solution like this one?

Keynote: Classification of Big Data Applications and Convergence of HPC and Cloud Technology Professor Geoffrey Fox, ACM Fellow, Indiana University, USA SKG2015: http://www.knowledgegrid.net/skg2015 Abstract We discuss study of the nature and requirements of many big data applications in terms of Ogres that describe important general characteristics. We develop ways of categorizing applications with features or facets that are useful in understanding suitable software and hardware approaches where 6 different broad paradigms are identified. This allows study of benchmarks and to understand when high performance computing (HPC) is useful. We propose adoption of DevOps motivated scripts to support hosting of applications on the many different infrastructures like OpenStack, Docker, OpenNebula, Commercial clouds and HPC supercomputers.

Welcome back to Growth Insights #15! David takes us through the best digital marketing tips from the last month, including a headline content generator and amazing prototype tools and web design tools! Get the latest tools list: https://grow.ac/issue15 Ever wanted Slack integrations to help you to search for things on Wikipedia without ever having to navigate away from the app? Maybe you’re wondering exactly how Russian propaganda is linked to the outcome of 2016’s American election. (Hint: It involves 2.700 fake Facebook accounts and 80.000 posts.) Or perhaps you're interested in web development tools? Well, we’ve got you covered with our essential growth tools toolkit. You’ll never have to guess about whether or not your new logo design will look good in real-life with a prototype tool, and you code your own self-destructing Banksy (we’d recommend using a photo of your most annoying colleague) with a brilliant web development tool. Think that visual search is still a distant dream? Not anymore - Snapchat just integrated it so that you can snap a product and buy the same product (or the nearest match to it on Amazon). And if you think that hardware hacks are old-school, factories in China were discovered to have nested tiny microchips, no bigger than a grain of rice, on the motherboards of expensive US servers. We're not suggesting this as one of our digital marketing tips, but it's interesting to know how they did it! Finally, don’t forget the headline content generator tool - simply pop in a keyword and instantly receive tonnes of headlines to help you create your content! So, there you have it! All the best digital marketing tips and tools we discovered this month, including prototype tools, a headline content generator, a few project management tools and a sprinkling of old-school hacking.

PAMAE: Parallel k-Medoids Clustering with High Accuracy and Efficiency Hwanjun Song (KAIST) Jae-Gil Lee (KAIST) Wook-Shin Han (POSTECH) The k-medoids algorithm is one of the best-known clustering algorithms. Despite this, however, it is not as widely used for big data analytics as the k-means algorithm, mainly because of its high computational complexity. Many studies have attempted to solve the efficiency problem of the k-medoids algorithm, but all such studies have improved efficiency at the expense of accuracy. In this paper, we propose a novel parallel k-medoids algorithm, which we call PAMAE, that achieves both high accuracy and high efficiency. We identify two factors—-“global search” and “entire data”—-that are essential to achieving high accuracy, but are also very time-consuming if considered simultaneously. Thus, our key idea is to apply them individually through two phases: parallel seeding and parallel refinement, neither of which is costly. The first phase performs global search over sampled data, and the second phase performs local search over entire data. Our theoretical analysis proves that this serial execution of the two phases leads to an accurate solution that would be achieved by global search over entire data. In order to validate the merit of our approach, we implement PAMAE on Spark as well as Hadoop and conduct extensive experiments using various real-world data sets on 12 Microsoft Azure machines (48 cores). The results show that PAMAE significantly outperforms most of recent parallel algorithms and, at the same time, produces a clustering quality as comparable as the previous most-accurate algorithm.

This is a work co-authored by Oliver Mattausch Daniele Panozzo, Claudio Mura, Olga Sorkine-Hornung, Renato Pajarola. The paper has been presented at Eurographics 2014. We present a method to automatically segment indoor scenes by detecting repeated objects. Our algorithm scales to datasets with 198 million points and does not require any training data. We propose a trivially parallelizable preprocessing step, which compresses a point cloud into a collection of nearly-planar patches related by geometric transformations. This representation enables us to robustly filter out noise and greatly reduces the computational cost and memory requirements of our method, enabling execution at interactive rates. We propose a patch similarity measure based on shape descriptors and spatial configurations of neighboring patches. The patches are clustered in a Euclidean embedding space based on the similarity matrix to yield the segmentation of the input point cloud. The generated segmentation can be used to compress the raw point cloud, create an object database, and increase the clarity of the point cloud visualization.

What is CANCER CLUSTER? What does CANCER CLUSTER mean? CANCER CLUSTER meaning - CANCER CLUSTER definition - CANCER CLUSTER explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A cancer cluster is a disease cluster in which a high number of cancer cases occurs in a group of people in a particular geographic area over a limited period of time. Historical examples of work-related cancer clusters are well documented in the medical literature. Notable examples include: scrotal cancer among chimney sweeps in 18th century London; osteosarcoma among female watch dial painters in the 20th century; skin cancer in farmers; bladder cancer in dye workers exposed to aniline compounds; and leukemia and lymphoma in chemical workers exposed to benzene. Cancer cluster suspicions usually arise when members of the general public report that their family members, friends, neighbors, or coworkers have been diagnosed with the same or related cancers. State or local health departments will investigate the possibility of a cancer cluster when a claim is filed. In order to justify investigating such claims, health departments conduct a preliminary review. Data will be collected and verified regarding: the types of cancer reported, numbers of cases, geographic area of the cases, and the patients clinical history. At this point, a committee of medical professionals will examine the data and determine whether or not an investigation (often lengthy and expensive) is justified. In the U.S., state and local health departments respond to more than 1,000 inquiries about suspected cancer clusters each year. It is possible that a suspected cancer cluster may be due to chance alone; however, only clusters that have a disease rate that is statistically significantly greater than the disease rate of the general population are investigated. Given the number of inquiries it is likely that many of these are due to chance alone. It is a well-known problem in interpreting data that random cases of cancer can appear to form clumps that are misinterpreted as a cluster. A cluster is less likely to be coincidental if the case consists of one type of cancer, a rare type of cancer, or a type of cancer that is not usually found in a certain age group. Between 5% to 15% of suspected cancer clusters are statistically significant.
