Data mining is the process of analyzing large amounts of data to discover hidden patterns and relationships. It involves several steps including data preparation, modeling, evaluation, and deployment. A standard process like CRISP-DM provides guidelines and documentation to make the data mining process reliable and repeatable. Data mining can be used for applications like forecasting, classification, clustering, association analysis, and sequencing to help organizations in areas such as fraud detection, customer relationship management, and risk management.

Nowadays, IT operations are required to run on a tight budget and under constant watch. Compliance, security and mobile innovation are making proper auditing of IT systems absolutely necessary. Knowing the most fundamental facts, like who changed what, when, and where, will save hours of troubleshooting, satisfy compliance needs, and secure the environment. This white paper shows a methodical approach to IT infrastructure auditing. That includes proper planning, estimation of time needed to implement an effective IT auditing solution, and critical resources.
Almost every business decision requires executives and managers to balance risk and reward, and efficiency in that process is essential to an enterprise’s success. Too often though, IT risk (business risk related to the use of IT) is overlooked.
While other business risks such as market, credit and operational risks have long been incorporated into the decision-making processes, IT risk has usually been relegated to technical specialists outside the boardroom, despite falling under the same risk category as other business risks: failure to achieve strategic objectives.
This session intends to address business risks related to the use of IT, looking at industry standards, frameworks and best practices, as well as focusing on real world examples and specific plans on how to implement IT Risk Management on every level of your company.

Big Data Analytics: Applications and Opportunities in On-line Predictive Mode...BigMine
Talk by Usama Fayyad at BigMine12 at KDD12.
Virtually all organizations are having to deal with Big Data in many contexts: marketing, operations, monitoring, performance, and even financial management. Big Data is characterized not just by its size, but by its Velocity and its Variety for which keeping up with the data flux, let alone its analysis, is challenging at best and impossible in many cases. In this talk I will cover some of the basics in terms of infrastructure and design considerations for effective an efficient BigData. In many organizations, the lack of consideration of effective infrastructure and data management leads to unnecessarily expensive systems for which the benefits are insufficient to justify the costs. We will refer to example frameworks and clarify the kinds of operations where Map-Reduce (Hadoop and and its derivatives) are appropriate and the situations where other infrastructure is needed to perform segmentation, prediction, analysis, and reporting appropriately – these being the fundamental operations in predictive analytics. We will thenpay specific attention to on-line data and the unique challenges and opportunities represented there. We cover examples of Predictive Analytics over Big Data with case studies in eCommerce Marketing, on-line publishing and recommendation systems, and advertising targeting: Special focus will be placed on the analysis of on-line data with applications in Search, Search Marketing, and targeting of advertising. We conclude with some technical challenges as well as the solutions that can be used to these challenges in social network data.
ADV Slides: What the Aspiring or New Data Scientist Needs to Know About the E...DATAVERSITY
Many data scientists are well grounded in creating accomplishment in the enterprise, but many come from outside – from academia, from PhD programs and research. They have the necessary technical skills, but it doesn’t count until their product gets to production and in use. The speaker recently helped a struggling data scientist understand his organization and how to create success in it. That turned into this presentation, because many new data scientists struggle with the complexities of an enterprise.
A lack of trust is inhibiting the adoption of #AI. This presentation discusses approaches to delivering trusted data pipelines for AI and machine learning
Engineering Machine Learning Data Pipelines Series: Big Data Quality - Cleans...Precisely
Making the hurdle from designing a machine learning model to putting it into production is the key to getting value back, and the roadblock that stops many a promising machine learning project. After the data scientists have done their part, engineering robust production data pipelines has its own set of tough problems to solve. Syncsort software helps the data engineer every step of the way.
Once you’ve got data pulled in from multiple sources, you need to assess the mess. In nearly every data set, there will be flaws. Missing data, misspelled data, misfielded data, dozens of common problems that need to be repaired before the data is ready to use. The data quality software that has been on the market for years is the obvious choice, since it already has the full toolset to assess the problems you’re up against and correct them. Unfortunately, most data quality software was built in the age of single server data warehouses and doesn’t scale to cluster-sized problems. It is also, traditionally, far too slow to support the kind of real-time use cases that drive the machine learning world.
When Syncsort bought Trillium, the industry leader in data quality software for over a decade, we combined Trillium Quality with Intelligent Execution, our artificially intelligent dynamic optimizer that provides excellent performance on MapReduce or Spark. Rather than coding everything from scratch and reinventing the data quality wheel, view this short webinar on-demand to learn how you can feed production machine learning models with shiny clean data while spending zero time on coding and performance tuning. These fifteen minutes could save you weeks.
Look no further than our comprehensive Data Science Training program in Chandigarh. Designed to equip individuals with the skills and knowledge required to thrive in today's data-centric world, our course offers a unique blend of theoretical foundations and hands-on practical experience.
Crowdsourcing Approaches to Big Data Curation - Rio Big Data MeetupEdward Curry
Data management efforts such as Master Data Management and Data Curation are a popular approach for high quality enterprise data. However, Data Curation can be heavily centralised and labour intensive, where the cost and effort can become prohibitively high. The concentration of data management and stewardship onto a few highly skilled individuals, like developers and data experts, can be a significant bottleneck. This talk explores how to effectively involving a wider community of users within big data management activities. The bottom-up approach of involving crowds in the creation and management of data has been demonstrated by projects like Freebase, Wikipedia, and DBpedia. The talk discusses how crowdsourcing data management techniques can be applied within an enterprise context.
Topics covered include:
- Data Quality And Data Curation
- Crowdsourcing
- Case Studies on Crowdsourced Data Curation
- Setting up a Crowdsourced Data Curation Process
- Linked Open Data Example
- Future Research Challenges
Patterns for Successful Data Science Projects (Spark AI Summit)Bill Chambers
Running data science workloads is challenge regardless of whether you are running them on your laptop, on an on-premises cluster, or in the cloud. While buying 100% managed service is an option, these tools can be expensive and lack extensibility. Therefore, many companies option for open source data science tools like scikit-learn and Apache Spark’s MLlib in order to balance both functionality and cost.
However, even if a project succeeds at a point in time with any set of tools, these projects become harder and harder to maintain as data volumes increase and a desire for real-time pushes technology to its limit. New projects also struggle as new challenges of scale invalidate previous assumptions.
This talk will discuss some patterns that we see at Databricks that companies leverage to succeed with their data science projects. Key takeaways will be:
– Striving for simplicity
– Removing cognitive load for you and your team
– Working with data, big and small
– Effectively leveraging the ecosystem of tools to be successful
There are ten areas in Data Science which are a key part of a project, and you need to master those to be able to work as a Data Scientist in much big organization.

A study on “impact of artificial intelligence in covid19 diagnosis”Dr. C.V. Suresh Babu
Although the lungs are one of the most vital organs in the body, they are vulnerable to infection and injury. COVID-19 has put the entire world in an unprecedented difficult situation, bringing life to a halt and claiming thousands of lives all across the world. Medical imaging, such as X-rays and computed tomography (CT), is essential in the global fight against COVID-19, and newly emerging artificial intelligence (AI) technologies are boosting the power of imaging tools and assisting medical specialists. AI can improve job efficiency by precisely identifying infections in X-ray and CT images and allowing further measurement. We focus on the integration of AI with X-ray and CT, both of which are routinely used in frontline hospitals, to reflect the most recent progress in medical imaging and radiology combating COVID-19.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

18. Phases in the DM
Process (1 & 2)
•Business Understanding:
– Statement of
Business Objective
– Statement of Data
•Data Understanding
Mining objective
– Explore the data and
– Statement of Success
verify the quality
Criteria
– Find outliers
19. Phases in the DM
Process (3)
• Data preparation:
– Takes usually over 90% of our time
• Collection
• Assessment
• Consolidation and Cleaning
– table links, aggregation level,
missing values, etc
• Data selection
– active role in ignoring non-
contributory data?
– outliers?
– Use of samples
– visualization tools
• Transformations - create new
variables
20. Phases in the DM Process
(4)
• Model building
– Selection of the modeling
techniques is based upon
the data mining objective
– Modeling is an iterative
process - different for
supervised and
unsupervised learning
• May model for either
description or prediction
21. Types of Models
•Prediction Models for •Descriptive Models for
Predicting and Grouping and Finding
Classifying Associations
– Regression algorithms – Clustering/Grouping
(predict numeric
outcome): neural algorithms: K-
networks, rule means, Kohonen
induction, CART (OLS – Association
regression, GLM) algorithms: apriori,
– Classification GRI
algorithm predict
symbolic outcome):
CHAID, C5.0
(discriminant analysis,
logistic regression)
23. Neural Networks
• Description
– Difficult interpretation
– Tends to ‘overfit’ the data
– Extensive amount of training time
– A lot of data preparation
– Works with all data types

25. Rule Induction
Description
• Intuitive output
• Handles all forms of numeric data, as well
as non-numeric (symbolic) data
C5 Algorithm a special case of rule
induction
• Target variable must be symbolic
28. Phases in the DM
Process (5)
• Model Evaluation
– Evaluation of model: how well it
performed on test data
– Methods and criteria depend on
model type:
• e.g., coincidence matrix with
classification models, mean
error rate with regression
models
– Interpretation of model:
important or not, easy or hard
depends on algorithm
29. Phases in the DM
Process (6)
•Deployment
– Determine how the results need to be
utilized
– Who needs to use them?
– How often do they need to be used
•Deploy Data Mining results by:
– Scoring a database
– Utilizing results as business rules
– interactive scoring on-line

34. Final Comments
• Data Mining can be utilized in any
organization that needs to find
patterns or relationships in their
data.
• By using the CRISP-DM
methodology, analysts can have a
reasonable level of assurance that
their Data Mining efforts will
render useful, repeatable, and
valid results.
The US Internal Revenue Service is using data mining to improve customer service. [Click] By analyzing incoming requests for help and information, the IRS hopes to schedule its workforce to provide faster, more accurate answers to questions.
The US DFAS needs to search through 2.5 million financial transactions that may indicate inaccurate charges. Instead of relying on tips to point out fraud, the DFAS is mining the data to identify suspicious transactions. [Click] Using Clementine, the agency examined credit card transactions and was able to identify purchases that did not match past patterns. Using this information, DFAS could focus investigations, finding fraud more costs effectively.
Retail banking is a highly competitive business. In addition to competition from other banks, banks also see intense competition from financial services companies of all kinds, from stockbrokers to mortgage companies. With so many organizations working the same customer base, the value of customer retention is greater than ever before. As a result, HSBC Bank USA looks to enticing existing customers to &quot;roll over&quot; maturing products, or on cross-selling new ones. [Click] Using SPSS products, HSBC found that it could reduce direct mail costs by 30% while still bringing in 95% of the campaign’s revenue. Because HSBC is sending out fewer mail pieces, customers are likely to be more loyal because they don’t receive junk mail from the bank.
