Data science and the art of persuasionAlex Clapson
The presentation of data science to lay audiences—the last mile—hasn’t evolved as rapidly or as fully as the science’s technical part. It must catch up, and that means rethinking how data science teams are put together, how they’re managed, and who’s involved at every point in the process, from the first data stream to the final chart shown to the board. Until companies can successfully traverse that last mile, data science teams will under deliver. They will provide, in Willard Brinton’s words, foundations without cathedrals.

Does more information elicit users’ compliance and engagement, or the other way around?
This paper explores the relationship between content strategy and user experience (UX). Specifically, we examine how the amount of information provided on marketing web pages, often called “landing pages,” impact users’ willingness to provide their e-mail address (a behavior called “conversion” in marketing terms). We describe the results of two large-scale online experiments (n= 535 and n= 27,900) conducted in real-world commercial settings. The observed results indicate a negative correlation between the amount of information on a web page and users’ decision-making and engagement.

How to use Big Data to drive product strategy and adoptionUXPA International
Today, billions of activities and interactions happen online. The level of interactions with online applications are getting more complex as well. Within the UX, we have the opportunity to understand collective behavior and various experiences through big data.
Specifically, large scale and strategical directions to products can be determined and evaluated through big data behavioral analysis. In this talk, I will go through various types of research objectives, appropriate methodologies and explain how we can use quantitative methodologies to solve UX and user behavior problems and drive product strategy. In this presentation, I will go through a couple of example case studies and topics where behavioral data can help us better understand users and inform strategic product development.

Research on People Counting Method Based on the Density Mapijtsrd
With the rapid development of science and technology and the rise of deep learning, in recent years, image based people counting has become a hot research topic in the field of computer vision. The method based on the density map retains the spatial information of the crowd in the picture, and on this basis, the network model of deep learning training is also used to improve the accuracy of the people counting. This paper mainly analyzes the traditional counting methods, introduces the common datasets used in people counting. We mainly conducted research and analysis on recent years people counting methods of generating high quality population density map through CNN method, the end to end convolutional neural network model surprised us with the accuracy of the people counting. Finally, this paper prospects the future research trend of people counting.

An expanding and expansive view of computing researchNAVER Engineering
My recent service for five years as the Assistant Director of the US National Science Foundation leading the Directorate of Computer and Information Science and Engineering has afforded me a broad view of computing research and education. The field of computing is in the midst of another “golden age” and is also at another nexus point – a point of change – where future research directions, and new ways in which research will be done, are coming into focus.
In this talk we will discuss these current and future CS research topics and trends, placing them in the context of the longer-term evolution of our field. We will also discuss computer science education (at several levels), as well as the forces that promise to disrupt not just computer science education, but higher education more broadly.
Cross discipline collaboration benefits from group think, a consolidation of soft system methodology and user focused design that all starts with design thinking that sees clients, designers, developers and information architects working together to address user problems and needs. As with any great adventure, design thinking starts with exploration and discovery.This presentation examines the high level tenants of system thinking, expands the scope of user thinking to include tools and devices that users employ to find out designs and delve into the specifics of design thinking, its methods and outcomes.
UXPA 2023: Learn how to get over personas by swiping right on user rolesUXPA International

Overview of Data and Analytics Essentials and FoundationsNUS-ISS
As companies increasingly integrate data across functions, the boundaries between marketing, sales and operations have been blurring. This allows them to find new opportunities that arise by aligning and integrating the activities of supply and demand to improve commercial effectiveness. Instead of conducting post-hoc analyses that allow them to correct future actions, companies generate and analyze data in near real-time and adjust their operations processes dynamically. Transitioning from static analytics outputs to more dynamic contextualized insights means analytics can be delivered with increased relevance closer to the point of decision.
This talk will cover the analytics journey from descriptive, predictive and prescriptive analytics to derive actionable and timely insights to improve customer experience to drive marketing, salesforce and operations excellence.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

7. Three ways in which “Personified Big Data”
drives the automation of personas
1. Access to online analytics and social media platforms via
application programming interfaces (APIs) for end-user data
2. Standardized format of aggregated end-user data (engagement
metrics, demographic groups)
3. Data analysis algorithms, libraries and software tools that enable
automation of whole pipeline from data collection to persona
generation to serving via interactive persona systems (end-to-end).

9. Why automate persona generation?
Personas are usually created with manual methods (i.e.,
interviews & ethnography), methods that are expensive
and slow to implement, and they can quickly become
outdated. Because of the limitations, personas risk being
inaccurate representations of the true user base.
Better
personas
Better
decisions
Better
results.
In contrast, APG provides personas that are fast to
create and updated automatically. This means the cost of
persona creation is dramatically reduced, making them
available for organizations with limited means (e.g.,
startups, small businesses). Depending on the underlying
dataset, APG can cover a wide range of behaviors and
demographics.

12. Research Roadmap for
Automatic Persona Generation (APG)
Information architecture:
How to choose relevant
persona information content
and presentation for a given
user, use case, and
industry?
Quotes:
How to find demographically
matching, non-toxic comments
that describe the persona’s
attitudes and are relevant for
end users?
Temporal analysis:
How to analyze change
of personas over time?
APG is about finding better ways to process and choose
useful user information from vast amounts of online data.
”Personas are about giving faces to data.”
Applicability: How to create
personas for specific industries
(e.g., e-health, e-commerce,
politics, gaming…)?
Image: How to
automatically generate, tag,
and choose appropriate
persona profile pictures?
Evaluation: (1) How to ensure
personas are of high quality
(complete, clear, consistent and
credible)? (2) How to measure
usefulness of personas for
individuals and organizations?
Attributes & Topics of
Interest: How to automatically
infer user attributes, such as
interests, needs, wants, goals,
political orientation, and brand
affinity from social media?

14. Issues about Pictures
• Need for manual
supervision / validation
• Demographically
imbalanced datasets
• Currently conditional
generation is not
supported

17. https://doi.org/10.1080/0144929X.2020.1838610
16. Issues about Algorithm
• Is clustering or dimensionality reduction meaningful for user
segmentation in the first place?
• From a diversity standpoint, it seems no
• Diversity maximization or using diversity as a goal has been
largely ignored in user segmentation and persona creation
• …how many personas should be created? (Depends on the
goal: what is the goal??)
• What algorithm performs the best? And, what METRIC is the
most appropriate (e.g., statistical distance vs. diversity)
17. Issues about Algorithm
• Concept drift / topic drift / model drift…
• All refer to CHANGE in the underlying user behavior (data)
• How often should personas be changed? How should the
change be measured / detected?
18. Issues about Quotes
• Bødker’s ”Frankenstein problem”: inconsistency of persona
information
• How to match the quotes with the personas’ demographics?
• Inconvenient cases: man woman, Indian Pakistanese,
etc. (cultural sensibilities (Häkkilä et al.))
19. Data is available but what about
information?
• Attitudes, fears, doubts, hopes, needs, wants… can these be
inferred from numbers?
• Tweets contain a lot… Rosetta’s Stone for data-driven
personas: user modeling / soft attribute inference from smartly
sampled tweets
• …even more important because persona users’ information
needs are unique --- need to have flexible tools for them to
query persona attitudes in real-time (static data-driven personas
won’t do)
20. Towards persona science?
• Persona analytics = how decision-makers (i.e.,
persona users) in organizations use personas as
analytical tools to better understand their users or
customers.
• Persona analytics = how persona creators or
researchers investigate the behaviors of persona
users.
We define ‘persona analytics’ (PA) as the systematic
measurement of behaviors and interactions of persona
users engaged with interactive persona systems. When
personas are provided through a web browser, PA takes
place via mouse- (and eye-)tracking that records the
persona users’ mouse (or gaze) movements and clicks
(eye fixations) on the provided persona profiles and
their information elements.
21. Empirical Persona User Research
(1) How do users interact with personas?
(2) What persona information do users pay attention to?
(3) What persona information causes users to change/reinforce their
attitudes?
(4) What persona information influences users’ decision making and
how?
(5) How and why do users choose a persona for their task?

24. Next steps
• Metrics
• What measures and
metrics we want to
analyze?
• Hypotheses
• Intervention →
expected change in
persona users’
behavior
Persona-based metrics User-based metrics
Time spent per persona =
Number of visits per persona =
Persona revisit frequency =
Number of personas visited =
Persona coverage =
Persona visit distribution =
Rank correlation =
Table 1: Persona Analytics metrics.
Behavioral matters such as order effects, revisit
frequency, persona comparisons, satisficing behavior, and
choice can be investigated deploying the persona state-
transition matrix and Markov Chain techniques. Persona
information design can be informed by dwell time
analyses, and typical persona viewing patterns and
information viewing patterns can be deduced in interactive
persona user studies using a live system.

25. Data-driven personas have room for all
lines of research
• Algorithmically oriented people can solve algorithmic problems in
generation, validation, updating, etc.
• Qualitatively oriented research can carry out user studies (e.g.,
observation, interviews)
• Empirically oriented researchers can conduct experiments using real
systems and controlled conditions
• Theoretically oriented scholars can attempt to formulate theories of
persona use and persona-user interaction
