A Generic Framework for Mining Top-k Representative Subgraph Patterns
 
01:03:50
Mining subgraph patterns is an active area of research. Till now, the focus has primarily been on mining all subgraph patterns in the given database. However, due to the exponential subgraph search space, the number of patterns mined, typically, is too large for any human mediated analysis. Consequently, deriving insights from the mined patterns is hard for domain scientists. In addition, subgraph pattern mining is posed in multiple forms: the function that models if a subgraph is a pattern varies based on the application and the database could be over multiple graphs or a single, large graph. A natural question that therefore arises is the following: Given any graph database type and a subgraph importance function, can we develop a technique to mine k subgraph patterns that best represent all other patterns of interest? We will discuss a generic framework called RESLING that answers this question. Experiments show that RESLING is up to 20 times more representative of the pattern space and 2 orders of magnitude faster than the state-of-the-art techniques.

Predicting Stock Price movement statistically
 
07:51
Predicting Stock Price movement statistically. Here we use historical data to predict the movement of stock price for next day. It is completely mathematically valid. The mathematical model of Brownian motion has several real-world applications. Stock market fluctuations are often cited, although Benoit Mandelbrot rejected its applicability to stock price movements in part because these are discontinuous. This is a momentum indicator used in technical analysis, which compares the stock's closing price to its price over the course of a particular time frame. During an upward trend in the market, a stock's share price will close near its high (highest price traded), and when in a downward-trending market, the security's price will close near the low (lowest price traded). This may determine whether a stock is overbought or oversold, thus predicting a possible momentum change. http://www.garguniversity.com Check out Ebook "Mind Math" from Dr. Garg https://www.amazon.com/MIND-MATH-Learn-Math-Fun-ebook/dp/B017QEIF18

"Text Mining Unstructured Corporate Filing Data" by Yin Luo
 
45:33
Yin Luo, Vice Chairman at Wolfe Research, LLC presented this talk at QuantCon NYC 2017. In this talk, he showcases how web scraping, distributed cloud computing, NLP, and machine learning techniques can be applied to systematically analyze corporate filings from the EDGAR database. Equipped with his own NLP algorithms, he studies a wide range of models based on corporate filing data: measuring the document tone or sentiment with finance oriented lexicons; investigating the changes in the language structure; computing the proportion of numeric versus textual information, and estimating the word complexity in corporate filings; and lastly, using machine learning algorithms to quantify the informative contents. His NLP-based stock selection signals have strong and consistent performance, with low turnover and slow decay, and is uncorrelated to traditional factors.

Web-based Inference Detection
 
49:26
Google Tech Talk February 13, 2009 ABSTRACT Presented by Jessica Staddon. Text content can allow unintended inferences. Consider, for example, the numerous people who have published anonymous blogs for venting about their employer only to be identified through seemingly non-identifying posts. Similarly, the US government's "Operation Iraqi Freedom Portal" was assembled as evidence of nuclear weapons presence in Iraq, but removed because it could be used to infer much of the weapon making process. We propose a simple, semi-automated approach to detecting text-based inferences prior to the release of content. Our approach uses association rule mining of the Web to identify keywords that may allow a sensitive topic to be inferred. While the main application of this work is data leak prevention we will also discuss how it might be used to detect bias in product reviews. Finally, if time permits, we will discuss how inference detection can support topic-driven access control. Most of this talk is joint work with Richard Chow and Philippe Golle. Jessica is an area manager at PARC (aka Xerox PARC). She received her PhD in Math from U. C. Berkeley and has held research scientist positions at RSA Labs and Bell Labs. Jessica's background is in applied cryptography, specifically, cryptographic protocols for large, dynamic groups. Her current research interests include the use of data mining to support content privacy. http://www.parc.com/jstaddon

Data Mining (Introduction for Business Students)
 
04:21
This short revision video introduces the concept of data mining. Data mining is the process of analysing data from different perspectives and summarising it into useful information, including discovery of previously unknown interesting patterns, unusual records or dependencies. There are many potential business benefits from effective data mining, including: Identifying previously unseen relationships between business data sets Better predicting future trends & behaviours Extract commercial (e.g. performance insights) from big data sets Generating actionable strategies built on data insights (e.g. positioning and targeting for market segments) Data mining is a particularly powerful series of techniques to support marketing competitiveness. Examples include: Sales forecasting: analysing when customers bought to predict when they will buy again Database marketing: examining customer purchasing patterns and looking at the demographics and psychographics of customers to build predictive profiles Market segmentation: a classic use of data mining, using data to break down a market into meaningful segments like age, income, occupation or gender E-commerce basket analysis: using mined data to predict future customer behavior by past performance, including purchases and preferences

Web Graph Models: Properties and Applications
 
46:14
In 1999 A. Barabasi and R. Albert suggested the idea of preferential attachment to explain the power law distribution of the vertex degrees in web graphs. Several mathematical models have then appeared incorporating this idea. Among them, the LCD model by B. Bollobas and O. Riordan, the Buckley--Osthus model, the Bollobas--Borgs-Chayes--Riordan model of directed scale-free graphs, etc. Many deep results have been obtained concerning these models. For example, one studies the degree distributions, the diameter, the clustering coefficient, and so on. In our work, we continue studying important statistics of the random web graph in the just-mentioned models. On the one hand, we substantially improve some of the formerly known results. On the other hand, we introduce new characteristics of the web including the number of edges between vertices of given degrees. For these characteristics, we find accurate analytic expressions and we apply them to improve quality of search engine rankings.

56:59
Abstract: A lot of research was done about clustering attacks of different types using many Machine Learning algorithms, with high rates of success. These were mainly done from the comfort of a research lab, with specific datasets and no performance limitations. In this session I will share my experience with dealing with clustering of attacks in near real-time scenarios where performance is a key factor, and where the reality punches lab statistics in the face. I will discuss some of the challenges we experienced during the research like: 1) Applying a clustering algorithm to a stream of data. 2) Extracting meaningful features from limited data. 3) Translating different features into something we can calculate distance from. Speaker Bio: ilad Yehudai is an algorithm developer and security researcher at Imperva’s web application research group. Gilad develops algorithms and solutions using state-of-the-art machine learning algorithms, and also researches new security threats and vulnerabilities. Gilad holds a B.Sc. and a M.Sc. in Mathematics from Tel Aviv University. He has a very analytical and technical background with experience in both statistics and machine learning.

How to : Do data mining
 
06:41
Do data mining One way that some corporations keep ahead of their competition is to do data mining. Businesses derive useful information from huge databases through statistical analysis. Applications of this mathematical algorithm based analysis tool are in the areas of product analysis, consumer research marketing, e-Commerce, stock investment trend and many more. Relational database mining, web mining, text mining, audio and video mining, and social networks mining are some types of data mining. You can relate data mining to geology in the sense that in geology you search for specific minerals (for example gold or lead), while a statistical data miner uses various tools to find useful information from a wide database. It is a way of extracting data from very large and sometimes complex databases to find patterns or trends that a company can use to further their business. Data mining is a labor intensive job wherein a lot of data has to be collected and analyzed. Outsourcing data mining jobs may be more beneficial to companies who do not have the time or manpower to invest in this endeavor. The outsourcing company will take care of collecting the needed data and organizing the data in a well mapped database so that they can easily filter or extract the required information for analysis. But if you have the resources, you can also use a variety of data mining programs out there. Some data mining software are SAS Enterprise Miner, DataDetective, Statistical Data Miner, Statistica, and Weka. You can read more about data mining on the Internet. But just to give you an idea, below are the steps in performing data mining: Define the objectives. This step is basically identifying why you need to perform data mining. What problem brought about a perceived data mining solution and what are the objectives for this project? Gather and organize the data. The bulk of the work in data mining is data gathering and exploring. Data has to be organized in an efficient and effective way for you to be able to process the information properly. Select the data-mining task. There are four basic data mining techniques: classification, regression, clustering and association rule. Choose the ones appropriate to your objectives. Modeling. This is when you actually perform the data mining procedure. Search for patterns in the database by applying your selected data mining techniques in order to create models. Data interpretation and validation. After the actual data mining task, the data gathered is now interpreted, validated, transformed and visualized using statistical techniques. Data deployment. This step can involve a report that is generated showing the patterns found in the data mining activity or the use of the data model on a larger group of data for further analysis. Data mining is an iterative process so you may have to go through several of the steps above a number of times until the results you derive answer your objectives. There was a time when data mining was not widely used by businesses. Now, public and private companies and organizations find data mining an invaluable way for them to keep up and even get ahead of their competitors. Businesses are now able to monitor the kind of customers their products cater to and what their customers’ buying behaviors are. The information mined and modeled from various types of databases is used for competition analysis, market research, economic trending, consumer behavior, industry research, geographical information analysis and so on. Even the FBI and other law enforcement groups use data mining techniques.

Neel Sundaresan, Partner Director, Cloud and Enterprise, Microsoft Description: In the recent years we have seen how Data Science, Machine Learning, and AI, in general, have been influencing and rewriting the rules in everything from commerce to healthcare to finance. Additionally, deploying to the cloud and has opened new opportunities for collecting and using data. We have quickly moved from using data for reporting to prediction to prescription to assisting rewrite the programs that generate the data in the first place. Bots rewriting themselves have got attention for both new productivity opportunities and fear of robot domination. Bootstrapping and program generation are well known in the programming language and compiler community. Traditionally these were done using rule based systems. With massive data on code and coder behavior and interactions, and processing power to create intelligence from this, one can envision new AI that blurs the distance between data and code and code development process. Combining interaction data with program and deployment data i In this talk we will discuss topics related to robotification of various aspects of software development, compiler systems, software processes for code review, deployment etc. through use of data and AI.

On the Anonymization of Sparse High-Dimensional Data
 
01:13
Title: On the Anonymization of Sparse High-Dimensional Data Domain: Data Mining Description: 1, Privacy preservation is the most focussed issue in information publication, on the grounds that the sensitive data shouldn't be disclosed. For this regard, several privacy preservation data mining algorithms are proposed. 2, Generalisation, Bucketisation and Anatomisation techniques are used as a part of this regard. They ensure the privacy of the user,either by modifying quasi identifier values or by including noise. 3, These techniques are well suited for low dimensional data and they expel the most valuable information from the dataset.In this work,we concentrate on protection against identity disclosure in the publication of sparse high dimensional data. 4, The sparse dataset which is scanty has less information distributed in the entire dataset.So,in the first phase we transform the dataset into a band matrix framework by coordinating Genetic algorithm with Cuckoo search algorithm.This makes the nearest rows associated and makes the non zero components near to the diagonal and lessens the search space and also memory. 5, In the other phase a novel anatomisation technique based on disassociation is introduced to safeguard privacy.This technique isolates the quasi identifier values with sensitive attributes and publishes quasi identifiers straightforwardly.Then density based clustering is employed to anonymise the underlying data,ands protects against identity disclosure and increases data utility The adversary cannot relate the sensitive value with high probability.Experimental results demonstrate that this technique decreases information loss, reconstruction error and increases data utility.

Neural Networks in Data Mining | MLP Multi layer Perceptron Algorithm in Data Mining
 
10:31
Classification is a predictive modelling. Classification consists of assigning a class label to a set of unclassified cases Steps of Classification: 1. Model construction: Describing a set of predetermined classes Each tuple/sample is assumed to belong to a predefined class, as determined by the class label attribute. The set of tuples used for model construction is training set. The model is represented as classification rules, decision trees, or mathematical formulae. 2. Model usage: For classifying future or unknown objects Estimate accuracy of the model If the accuracy is acceptable, use the model to classify new data MLP- NN Classification Algorithm The MLP-NN algorithm performs learning on a multilayer feed-forward neural network. It iteratively learns a set of weights for prediction of the class label of tuples. A multilayer feed-forward neural network consists of an input layer, one or more hidden layers, and an output layer. Each layer is made up of units. The inputs to the network correspond to the attributes measured for each training tuple. The inputs are fed simultaneously into the units making up the input layer. These inputs pass through the input layer and are then weighted and fed simultaneously to a second layer of “neuronlike” units, known as a hidden layer. The outputs of the hidden layer units can be input to another hidden layer, and so on. The number of hidden layers is arbitrary, although in practice, usually only one is used. The weighted outputs of the last hidden layer are input to units making up the output layer, which emits the network’s prediction for given tuples. Algorithm of MLP-NN is as follows: Step 1: Initialize input of all weights with small random numbers. Step 2: Calculate the weight sum of the inputs. Step 3: Calculate activation function of all hidden layer. Step 4: Output of all layers For more information and query visit our website: Website : http://www.e2matrix.com Blog : http://www.e2matrix.com/blog/ WordPress : https://teche2matrix.wordpress.com/ Blogger : https://teche2matrix.blogspot.in/ Contact Us : +91 9041262727 Follow Us on Social Media Facebook : https://www.facebook.com/etwomatrix.researchlab Twitter : https://twitter.com/E2MATRIX1 LinkedIn : https://www.linkedin.com/in/e2matrix-training-research Google Plus : https://plus.google.com/u/0/+E2MatrixJalandhar Pinterest : https://in.pinterest.com/e2matrixresearchlab/ Tumblr : https://www.tumblr.com/blog/e2matrix24

Recommender Problems for Web Applications, 4/26/2010
 
01:24:46
Please also see http://www.sfbayacm.org/?p=1579 for links to the presentation slides and other related documents. DESCRIPTION: Several web applications like content optimization and online advertising involve recommending items from an inventory for each user visit to maximize some yield metric of interest (e.g. click rates). These are instances of large scale recommender system problems that entail several statistical challenges. We provide a mathematical description of the problem followed by modeling solutions for a content optimization problem that arises in the context of Yahoo! Front Page (www.yahoo.com). In fact, we discuss models to a) serve most popular items, b) serve items that are most popular in different user segments and c) provide personalized item recommendations for each user. Our models are based on time series methods, multi-armed bandit schemes and bilinear random effects model. One class of bilinear random effects model we propose extends reduced rank regression to incomplete matrices, the other class extends matrix factorization to incorporate covariates. Throughout, concepts are illustrated with examples and results obtained from "bucket tests" conducted on a real system. SPEAKER BIOGRAPHY: Deepak Agarwal is currently a Principal research scientist at Yahoo! Research. Prior to joining Yahoo!, he was a member of the statistics department at AT&T Research. He is a statistician interested in scalable modeling approaches for large scale applications. He has done extensive research on large scale hierarchical random effects model, computational advertising, modeling massive social networks with applications to call graph that arise in the telecommunications industry and modeling massive dyadic data that arise in applications like recommender systems. He has won four best paper awards (JSM 2001, SDM 2004, KDD 2007, ICDM 2009) that are directly related to the material of the talk. He has also done research in anomaly detection using a time series approach and computational approaches for scaling spatial scan statistic to large data sets. He regularly serves on program committees of data mining and machine learning conferences. He is currently associate editor for Journal of Americal Statistical Association, the top journal in the field of Statistics. He have given two tutorials on Statistical Challenges in Online Advertising at CIKM 2009 and KDD 2009. Deepak in collaboration with his co-authors have developed algorithms for real recommender systems that have been successfully deployed and thus has experience with both practical and scientific issues that arise in such applications.

Match the applications to the theorems: (i) Find the variance of traffic volumes in a large network presented as streaming data. (ii) Estimate failure probabilities in a complex systems with many parts. (iii) Group customers into clusters based on what they bought. (a) Projecting high dimensional space to a random low dimensional space scales each vector's length by (roughly) the same factor. (b) A random walk in a high dimensional convex set converges rather fast. (c) Given data points, we can find their best-fit subspace fast. While the theorems are precise, the talk will deal with applications at a high level. Other theorems/applications may be discussed.

With data being so readily available, we're becoming overly reliant on it. Putting your blind faith in data can be perilous. Often there can be a confounding factor that is hidden within your data that will tell a different story. In this video we show a couple of confounding examples in the Simpson's Paradox. The UCBerkeley sex discrimination law suit is one of the classic simpson's paradox examples (as well as a confounding example). However, we also go through a business strategy case example of how Simpson's Paradox can lead you to make the wrong decisions. Understanding your data analytics correctly is key for business strategy in the new aga - and hence we include this study in the SkipMBA DIY MBA (self mba).

Hemant Purohit Dissertation Defense “MINING BEHAVIOR OF CITIZEN SENSOR COMMUNITIES TO IMPROVE COOPERATION WITH ORGANIZATIONAL ACTORS” Ph.D. Committee: Drs. Amit Sheth, Advisor, TK Prasad, Guozhu Dong, Valerie Shalin, Psychology, Srinivasan Parthasarathy, CSE, Ohio State University, and Patrick Meier, QCRI ABSTRACT: Social media provides a natural platform for dynamic emergence of citizen (as) sensor communities, where the citizens share information, express opinions, and engage in discussions. Often such a Online Citizen Sensor Community (CSC) has stated or implied goals related to workflows of organizational actors with defined roles and responsibilities. For example, a community of crisis response volunteers, for informing the prioritization of responses for resource needs (e.g., medical) to assist the managers of crisis response organizations. However, in CSC, there are challenges related to information overload for organizational actors, including finding reliable information providers and finding the actionable information from citizens. This threatens awareness and articulation of workflows to enable cooperation between citizens and organizational actors. CSCs supported by Web 2.0 social media platforms offer new opportunities and pose new challenges. This work addresses issues of ambiguity in interpreting unconstrained natural language (e.g., ‘wanna help’ appearing in both types of messages for asking and offering help during crises), sparsity of user and group behaviors (e.g., expression of specific intent), and diversity of user demographics (e.g., medical or technical professional) for interpreting user-generated data of citizen sensors. Interdisciplinary research involving social and computer sciences is essential to address these socio-technical issues in CSC, and allow better accessibility to user-generated data at higher level of information abstraction for organizational actors. This study presents a novel web information processing framework focused on actors and actions in cooperation, called Identify-Match-Engage (IME), which fuses top-down and bottom-up computing approaches to design a cooperative web information system between citizens and organizational actors. It includes a.) identification of action related seeking-offering intent behaviors from short, unstructured text documents using both declarative and statistical knowledge based classification model, b.) matching of intentions about seeking and offering, and c.) engagement models of users and groups in CSC to prioritize whom to engage, by modeling context with social theories using features of users, their generated content, and their dynamic network connections in the user interaction networks. The results show an improvement in modeling efficiency from the fusion of top-down knowledge-driven and bottom-up data-driven approaches than from conventional bottom-up approaches alone for modeling intent and engagement. Several applications of this work include use of the engagement interface tool during recent crises to enable efficient citizen engagement for spreading critical information of prioritized needs to ensure donation of only required supplies by the citizens. The engagement interface application also won the United Nations ICT agency ITU's Young Innovator 2014 award. Additionally, the intent classification technology for identifying seeking-offering of help during a crisis was integrated by the crisis-mapping pioneer Ushahidi’s project, CrisisNET for broader impact.
