Data-centric AI and the convergence of data and model engineering: opportunit...Paolo Missier
A keynote talk given to the IDEAL 2023 conference (Evora, Portugal Nov 23, 2023).
Abstract.
The past few years have seen the emergence of what the AI community calls "Data-centric AI", namely the recognition that some of the limiting factors in AI performance are in fact in the data used for training the models, as much as in the expressiveness and complexity of the models themselves. One analogy is that of a powerful engine that will only run as fast as the quality of the fuel allows. A plethora of recent literature has started the connection between data and models in depth, along with startups that offer "data engineering for AI" services. Some concepts are well-known to the data engineering community, including incremental data cleaning, multi-source integration, or data bias control; others are more specific to AI applications, for instance the realisation that some samples in the training space are "easier to learn from" than others. In this "position talk" I will suggest that, from an infrastructure perspective, there is an opportunity to efficiently support patterns of complex pipelines where data and model improvements are entangled in a series of iterations. I will focus in particular on end-to-end tracking of data and model versions, as a way to support MLDev and MLOps engineers as they navigate through a complex decision space.

Abstract
We argue that the data integration (DI) community should devote far more effort to building systems,
in order to truly advance the field. We discuss the limitations of current DI systems, and point out that
there is already an existing popular DI “system” out there, which is PyData, the open-source ecosystem
of 138,000+ interoperable Python packages. We argue that rather than building isolated monolithic DI
systems, we should consider extending this PyData “system”, by developing more Python packages that
solve DI problems for the users of PyData. We discuss how extending PyData enables us to pursue an
integrated agenda of research, system development, education, and outreach in DI, which in turn can
position our community to become a key player in data science. Finally, we discuss ongoing work at
Wisconsin, which suggests that this agenda is highly promising and raises many interesting challenges.
1 Introduction
In this paper we focus on data integration (DI), broadly interpreted as covering all major data preparation steps
such as data extraction, exploration, profiling, cleaning, matching, and merging [10]. This topic is also known
as data wrangling, munging, curation, unification, fusion, preparation, and more. Over the past few decades, DI
has received much attention (e.g., [37, 29, 31, 20, 34, 33, 6, 17, 39, 22, 23, 5, 8, 36, 15, 35, 4, 25, 38, 26, 32, 19,
2, 12, 11, 16, 2, 3]). Today, as data science grows, DI is receiving even more attention. This is because many
data science applications must first perform DI to combine the raw data from multiple sources, before analysis
can be carried out to extract insights.
Yet despite all this attention, today we do not really know whether the field is making good progress. The
vast majority of DI works (with the exception of efforts such as Tamr and Trifacta [36, 15]) have focused on
developing algorithmic solutions. But we know very little about whether these (ever-more-complex) algorithms
are indeed useful in practice. The field has also built mostly isolated system prototypes, which are hard to use and
combine, and are often not powerful enough for real-world applications. This makes it difficult to decide what
to teach in DI classes. Teaching complex DI algorithms and asking students to do projects using our prototype
systems can train them well for doing DI research, but are not likely to train them well for solving real-world DI
problems in later jobs. Similarly, outreach to real users (e.g., domain scientists) is difficult. Given that we have

How can engineers make steel that doesn\'t baulk at hydrogen?
For over 100 years engineers have known that hydrogen can cause metals to become incredibly
brittle, but they\'ve been able to do little to protect against it. Now, Oxford University researchers
are working on a large collaborative project to build the metals of the future, that can retain their
strength in the presence of this disruptive gas.
Steel has a reputation for being strong: it\'s used in everything from your car\'s chassis and the
reinforced concrete joists that supports buildings, to the internal workings of jet engines and the
cables that hold up the world\'s largest suspension bridges. But while advances in high-strength
steel technology theoretically allow engineers to use less of the material – making it possible to
create structures that are lighter as well as stronger – there exists a problem holding some of the
materials back from widespread adoption.
There are new materials sitting on the shelf that could be used for many kinds of applications –
construction, aerospace, cars, all sorts,\' explains Professor Alan Cocks from the University\'s
Department of Engineering Science. \'But companies are afraid to use some of them because of
their susceptibility to what\'s known as hydrogen embrittlement.\' First observed before the turn
of the 20th century, hydrogen embrittlement is a phenomenon where some materials –
particularly steel, but also metals like zirconium and titanium – become far weaker when
exposed to hydrogen.
Professor Cocks points out that some steels can suffer a decrease in strength by as much as a
factor of 10 when they\'re exposed to hydrogen, which means that they could fail when subjected
to just a tenth of the maximum stress they can usually withstand. If engineers could find a way to
overcome this weakness, they could more confidently use some materials – predominantly steels,
but also the likes of titanium for aerospace applications or the zirconium sheathing of nuclear
power rods.
\'It seems like it should be a straightforward problem to solve,\' explains Professor Cocks. \'But
there\'s immense controversy about why it happens, and despite lots of experimental studies and
theoretical modelling there\'s still no real solution.\' That\'s why researchers from Oxford
University are working on a large collaborative project – along with Cambridge University,
Imperial College London, King\'s College London and the University of Sheffield – to finally
understand its causes and build new materials that overcome them.
To make progress, the researchers decided to put together a team that understood metals from the
atom up. So the team includes Oxford scientists from the Department of Materials, who
investigate how materials work at the atomic level, and from the Department of Engineering
Science, who model the larger-scale properties of the materials and the ways that hydrogen can
move through the metallic s.

and still others stay the same over time.
The following are several examples of a secular trend..
Submit the introduction to fraud as it applies to your case study of.pdfakilastationarrymdu
Submit the introduction to fraud as it applies to your case study of WorldCom analysis. Consider
the elements of fraud, the theories of crime causation, red flags of evidence based on the
elements of the fraud triangle, regulatory and legal factors in preventing and/or detecting fraud,
and developments in the accounting industry that impact fraud investigation
Solution
Fraud:Fraud simply meaning is a false representation of a matter of fact-whether it is by a word
or by conduct or by hiding that was required or important to disclose.Gaining an unfair
advantage over another person is considered fraud (Romney & Steinbart 2008). To be considered
a fraud, the deception must be characterized by “a false statement, representation, or disclosure”;
“a material fact,” that causes the fraudster to initiate the fraud; the “intention to deceive”; a
“justifiable reliance” of the fraudster on the misstatements; and an injured party.While there are
different types of fraud, the most common type of fraud is the misstatement of financial
statements (Albrecht & Albrecht, 2004). The fraud is committed on behalf of the organization,
usually through the acts of top management, as in the case of WorldCom. In management fraud,
management is the perpetrator and the companys stockholders, lenders, and other users of
financial information are the victims (Albrecht & Albrecht 2004).The reason behind these
manipulations is usually to “increase the companys stock price, meet cash flow needs, or hide
company losses and problems”.
The final element of the fraud triangle is rationalization: a form of justification in the mind of the
perpetrators of their illegal behavior (Romney & Steinbart, 2008). Most perpetrators, as in the
case of WorldCom, are first-time offenders with no criminal background that allows them to use
rationalization to hide their dishonesty (Albrecht & Albrecht, 2004). Due to the economic
conditions that existed at the time of the fraud, the managers who made the journal entries
presumed the misstatement to be a one-time act (Beresford, Katzenbach, & Rogers, 2003).
WorldCom, a telecommunications company, was a victim of these expectations that led to the
evolution of a fraud designed to deceive the public until the economic outlook improved.
Through understanding what led to the fraud, how the fraud grew, and what its effects were,
lessons can be derived to gain a better understanding of the reasons behind a fraud and to prevent
future frauds from occurring or growing as big as the WorldCom fraud did..

Submit your hypothesis development and investigation plan for your c.pdfakilastationarrymdu
Submit your hypothesis development and investigation plan for your company. Consider
potential frauds and perpetrators in your company, how the fraud could be investigated,
regulatory issues, and any other fraud risk inquiries required. Once you have developed your
fraud hypothesis, propose an investigation plan. Describe the process of how you would
investigate the potential fraud and all of the factors that must be considered for carrying out the
investigation. what would you include. the company that im investigating is Worldcom?
Solution
Answer;
Fraud is a significant problem for organisations of all kinds from publicly tarded corporation to
community based non for profits. To minimize financial and operational damage, it is important
to stay calm and follow step by step plan.
Why conduct a fraud examination ?
There are many reason why organizations choose to conduct fraud examination. A properly
excuted fraud examination can address a number of organizational objectives including:
1. Identified improper conduct
2. Identifying the persons responsible for improper conduct
3. Stopping Fraud
4. Sending a message throughout the organization that fraud will not be tolerated.
5. Determining the extent of potential liabilities or losses that might exist.
6. Stopping future losses
7. Strenghening internl control weakness.
The term fraud exaimination refers to a process of resolving allegations of fraud from inception
to disposition, and it is the primary function of the anti fraud professional. Below is the fraud
examination process:
1. Obtaining Evidence
2. Reporting
3. Testifying
4. Assisting in fraud detection and prevention.
Worldcom, now known as MCI Inc was founded in 1983 as LDDS. The telecommunication
company experienced rapid growth in the 1990s primarily due to several large acqusitions. The
company became World com inc. in 1995 following the purchase of Williams
Telecommunication Group Inc .
In early 2002 , during the internal audit , it was discovered that worldcom had made several
transfer that were not in accordance with U.S GAAP. The in correct accounting used involved
internal transfer within expense and capital expenditure accounts, as well as large personal loans
by the company totaling around $400 million.
The SEC officially filed fraud charges against WorldCom on Jun 26,2002. Immediately folloeing
this news, the stock price of world Com shares plummeted. Stock had recently been trading
around $ 15 per share, but fell to $ 0.20 folowing reports of fraud charges.Not only were
investors affected in the immediate aftermath, but also employees. Within three days of
announcment, 17,000 employee were fired..

What would you say are the advantages and disadvantages of electronic communication? For
example, hardly anyone faxes any more, we email. Do you feel texting is the next evolution for
business communication? Or, is there something else? How do you take advantage of modern
communication channels?
Solution
Advantages of electronic communication are as following:
1. Fast processing
2. It can reach to many people in one go
3. Information sharing on real-time basis
4. Connectivity from anywhere anyplace
5. Flexible working and connectivity to remote locations have become possible
Disadvantages:
1. Theft of data
2. Hacking of account can happen
3. Breeching of privacy
Texting is the basic element of communication. in modern time it is being done through emails.
so, the system what we are using to convey the message or communicate is evolving and at
present scenario it is email or push mail through smart phones. Another aspect is SMS we send.
it is evolving as it is also helping in business development besides helping in spreading short and
effective communication.
There are many advantages of modern communication channel.

Suppose a point is randomly selected along a line segment of length .pdfakilastationarrymdu
Suppose a point is randomly selected along a line segment of length L. What is the probability
the longer of the two segments on either side of this point is more than twice as long as the
shorter segment?
Solution
ok..see....the critical point is 1/3L because (1-1/3L) = 2L/3 which is twice the
shorter length. so..divide the line by a point at 1/3L or before it. So, (1L/3)/L = 1/3.

Suppose a Math 1040 class has 25 students and 5 if them are not pun.pdfakilastationarrymdu
Suppose a Math 1040 class has 25 students and 5% if them are not punctual. Let the random
variable X represent the number of students which are late to class. Find the mean of X, the
average
number students late to class, and the standard deviation of X.
I believe the mean is np= 25*.05= 1.25
The standard deviation would be (np(1-.05)) = (1.25*.95) = 1.09
But how would you finf the average? Is it just the meam, 1.25?
Solution
You\'re correct, the average and the mean are the same thing (1.25)..
Suppose a large number of new immigrants enter the labor market. Ass.pdfakilastationarrymdu
Suppose a large number of new immigrants enter the labor market. Assume this increase in the
supply of labor provides a drag on wage increases: wages rise by less than the prevailing rate of
inflation over the next year. Use the short-run model to explain how the economy responds to
this change.
**Please show detailed work and supporting graphs.
Solution
i cannot draw graph, but clearly explain in detail,you can understan easily.
when new immigrants enter into a place, the immediate impact is on essential commodities like
food products, housing requirements and all other servicess. because of increasing in number the
demand for all the services and products will be increse, supply will remain same. so, once
demand is higher than supply the prices will goes up, what we usually called as inflation.
because of increase in labor the wages will comes down, the people income levels come down
and their expenditure levels also comes down. if they are not in a position to buy goods and
services, the demand for these products declines and it also impacts the employability.
in short run we assume that few of the factors of inputs are constant like land, material and
capital. ofcourse the labor power is variable input, but according to the increase in labor levels
the production of output can not be increased. because all the remaning inputs are assumes
constant in short term.
if the situation contineous for a long time, in long term all factors of inputs are variable and
increase in inputs leads to increase in productivity and employment in the particular nation..
Suppose a function F(z) is a product of n differentiable functio.pdfakilastationarrymdu
Suppose a function F(z) is a product of \"n\" differentiable functions:
F(z)=f1(z)f2(z)f3(z)...fn(z).
Find F\'(z)/F(z) in simplest form.
(Its F prime in the numerator. Its not very clear because of the font.)
Solution
F(z)=f1(z)f2(z)f3(z)...fn(z) while differentiating one function will be differentiated
and others will remain constant F\'(z)=f1\'(z)f2(z)f3(z)...fn(z) + f1(z)f2\'(z)f3(z)...fn(z) +
f1(z)f2(z)f3\'(z)...fn(z) .................. + f1(z)f2(z)f3(z)...fn\'(z) F\'(z)/F(z) = [ f1\'(z)f2(z)f3(z)...fn(z)

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
