How to Make Things Simpler by Adding Complexity

Session - C.MERRELL STONE

Using “big data” is no longer sufficient. As we’ve become more competent with leveraging data at scale, we find ourselves digging deeper into understanding not just the data, but also the interrelationships between all those data. This is the essence of what is called, by some, “graph thinking” – using network science to map out data into different nodes, edges, even different layers of interconnected graphs (hypergraphs). This talk will explore how adding one more element, complexity science, can actually simplify decision making at multiple levels of an organization. Building on Dave Snowden’s Cynefin model of decision making, I’ll discuss how tools like agent-based modeling can make our models less-wrong, as well as endow us with some of the same powers of machine learning.

Leveraging Probabilistic Thinking in the Age of Quantum Computing

Session - DIANA WOLFE

As we navigate the rapidly evolving landscape of the digital age, we find ourselves facing a plethora of uncertainties. But as with any great scientific exploration, these uncertain times present opportunities for growth and adaptation. In a world where data is king, the ability to reason about uncertainty and make decisions based on incomplete or uncertain information is becoming more crucial than ever. And at the forefront of this endeavor is probabilistic thinking, a key component of approaches in machine learning and artificial intelligence. Now, with the advent of quantum computing, the field of data sciences is on the brink of a new frontier. To fully capitalize on the power of quantum computing, we must adopt a probabilistic mindset and understand the unique characteristics of quantum computing and its impact on the field of data sciences.

Why some homes sell quickly and others linger: a survival analysis of listings in the pandemic housing market

Session - ANUShna prakash

The pandemic saw some of the hottest for-sale market conditions on record, which abruptly cooled in 2022 as mortgage rates rose and reached new highs. In the span of a year, buyers and sellers went from a market in which homes went pending in less than a week to a month or more. The slowdown did not affect all homes equally. While on average homes were spending longer on the market (measured by median days on market), prior research found that there exists a subset of homes that continue to go under contract rapidly. We use survival analysis techniques (known as event history analysis or duration models) to identify the different factors that influence the time to sell a home across metropolitan areas in the U.S., including home characteristics as explanatory variables such as bedrooms, bathrooms, square footage, the age of the home. A survival-analysis approach allows us to use information about the time a property stays on market before going to pending – including if it has yet to go pending– to measure the relative importance of various factors. Preliminary results suggest that the median duration to pending has changed year over year, and that employing our approach tells a more nuanced story than looking at other more commonly-used metrics, such as median days to pending.

Access and Retrieve DNA Sequencing Data Using Python for Analysis

Session - FARaz rahman

We are all aware that data science, machine learning, and artificial intelligence are some of the most innovative and emerging fields of the 21st century, and that these fields will continue to be significant as long as there is trustworthy data available for analysis and application. However, it is not always simple to access data, and data scientists are frequently stymied by complex external APIs. This is due to a number of factors, the most prominent of which is that the focus of most data science courses is more on building complex machine learning and AI algorithms and less on identifying and retrieving data from credible sources that are accessible via various open source APIs. Bringing domain expertise into play further complicates the situation. The rules of data science in the real world differ from what is taught in online courses, and it goes without saying that employers are now seeking data scientists or data professionals who can collaborate with software engineers to write scalable and reproducible code in addition to building complex machine learning models. To address this issue, my proposal is to walk the audience through a data engineering pipeline that will allow them to easily access and retrieve DNA sequencing data from National Center for Biotechnology Information (NCBI’s) open source Sequence Read Archive (SRA) database and parse them in python for subsequent use in analytics. DNA sequencing is useful in numerous fields, such as determining ancestry, diagnosing possible diseases, and identifying new Covid variants. As an illustration, I will demonstrate how to retrieve SARS-CoV-2 sequencing data from NCBI's sequencing database and evaluate its quality. Audience members will be able to comprehend the specifics of sequencing data and acquire a solid understanding of Biotechnology data parsing and its application. It will give our audience the ability and confidence to retrieve and analyze their data which they can replicate in any field they want to and build a portfolio of meaningful projects to showcase their skills to the employers.

The Gender Disparity of Refugee Earnings in the United States

Session - subhadra vadlamannati

The refugee crisis impacts both low and high-income countries alike, and the question of refugee assimilation receives much attention worldwide. While all refugees face various challenges in assimilating to their host countries, female refugees face additional challenges. My talk leverages Data Science techniques to study the earnings of refugees upon arrival to their host countries. I used the 2018 Annual Survey of Refugees to study the earnings trajectory of male and female refugees who arrive in the United States. From analyzing this data I found that gender (p <0.001) and years of schooling (p< 0.05) are the most significant variables impacting pay. Surprisingly, none of the other variables including proficiency in English, Age and University degree seem to have a statistically significant impact. Using linear regression models to study the differences in male and female refugee pay reveals a significant earnings gap of approximately $1.70 an hour, which is equivalent in pay to female refugees receiving almost eight more years of schooling.

To examine the underlying mechanism behind this result, I studied how the predicted earnings trajectory varies when including the UNDP Human Development Index and the World Economic Forum Global Gender Gap variable, using refugees’ country of birth. My findings indicate robust results that female refugees do not benefit from increases in human development, while both male and female refugees benefit from increases in gender equality. These results have important implications for refugee policy in the form of cash assistance or vocational training.

The output of this research led me to dive deeper into aspects that impact refugee assimilation in the US. The second part of the presentation focuses on this project.

A key contributor to refugee success in the US is the level of education they can achieve despite the large language barrier. It is scientifically proven that leveraging a person’s strength in their native language accelerates their learning of another language as well as other concepts such as STEM. Unfortunately, for speakers of marginalized languages and dialects, it is a challenge to find bilingual content in their native language to help them learn English. I therefore embarked on building a mobile library app that uses Machine learning techniques to translate children's books from English to the learner's native language to generate a bilingual book in real time. The presentation will provide insights into the challenges of applying ML techniques such as OCR and machine translation during this project.

Exploring Knowledge Graphs for the Preservation of Orcas in the Pacific Northwest

Session - melly beechwood

The Pacific Northwest is home to a diversity of animal species, including the iconic orca, however increasing threats are making it difficult for these animals to survive. In order to properly address these threats, it is essential that policy makers have an accurate and comprehensive understanding of the species and its environment. A knowledge graph can provide an effective platform to combine the research from disparate sources – from biologists to local citizens – and create an overall view of the situation. This talk will explore the use of a knowledge graph to inform policy decisions, from the collection of citizen observations to natural language processing, to the global insights that could be gleaned from a well-constructed knowledge graph. By providing an overview of this powerful tool, this talk will help demonstrate how knowledge graphs could be used to help mitigate the decline of orcas in the Pacific Northwest.

Accelerating Experiment Design: Beyond A/B Testing

Session - apurvaA subramaniam

In the past few years, according to a new McKinsey Global Survey of executives, companies have accelerated the digitization of their customer and supply-chain interactions and of their internal operations by three to four years, and the share of digital or digitally enabled products in their portfolios has accelerated by seven years.

As a result, more companies are adopting Online Controlled Experiments to estimate the impact of business innovations and enable data-driven decision making at scale. Fixed horizon A/B testing is the go-to experiment design in industry, and it works well in a lot of scenarios. However, in cases such as multiple test variants, low traffic, high variance population, etc, optimizing traditional A/B testing as well as using other experiment designs can help accelerate the experimentation process and thus enable faster decision making.

In this talk, I will give an overview of a few different techniques for making experimentation faster:

1. Optimal Triggering

2. Variance Reduction

3. Sequential Testing

4. Multi-Armed Bandit

I will give examples of when to consider using these techniques, how to get started, pros and cons, and resources for further reading. This talk will help attendees who are familiar with A/B testing expand their experimentation design toolkit.

A/B Testing Using Propensity Score Matching

Session - juilee bhosale

Control groups are a crucial aspect of experimental research, allowing researchers to compare outcomes of an experimental group to a group that is similar but not exposed to the treatment. However, designing an appropriate control group can be challenging, due to presence of confounding variables that can introduce bias and affect the outcome of the study.

In this talk, I discuss the use of propensity score matching to find statistically comparable groups and mitigate confounder bias in experiments. Propensity score matching is a statistical technique used to control for potential confounding variables in A/B testing, and is particularly useful when comparing groups that are not randomly assigned to receive a treatment or product. We begin by reviewing the basic concepts of propensity scores matching and the statistical techniques to calculate scores and find comparable statistical control using these scores. We also discuss the use of covariate balance measures to assess the quality of the matching and the importance of using multiple rounds of matching to further refine the comparison groups. The talk discusses the advantages of using propensity score matching in experimental design, including the ability to reduce bias and improving attribution of outcomes to treatment in a study and provides examples of how propensity score matching can be implemented in practice. To conclude we walk through the usefulness of this approach through a case study and discuss the potential applications and limitations of propensity score matching in experimental design.

Applicants can feel overwhelmed and downright discouraged by job descriptions that scope a broad data science life cycle (e.g. data exploration, data engineering, statistical modelling, and data visualization), expertise across a diverse and evolving data science tech stack, and often times a specialized domain experience relevant to the data of interest. In this workshop I will present 10 strategies that we can apply to decode that job description so that you can apply and interview with confidence.

1. Before you apply, do your homework: List the top skills and responsibilities that you want to learn or leverage in a new role.

2. Now do your extra credit: List the domains, i.e. business or fields of application, that you want to learn or leverage in a new role.

3. Decode the role: Map your goal skills and responsibilities to those presented. Smaller teams with many skills and responsibilities may signal growth opportunities while larger teams with specialist roles may signal advancement in technical skill depth.

4. Decode the domain: Connect your goal domains to the list presented by considering your experience, education and interest.

5. Validate your model: Craft three interview questions that you need answered to determine if there is the right assumed opportunity based on your decoding.

6. Validate your application: Craft three connections that you want to highlight in your application through your resume and/or cover letter.

7. Network for feedback: Leverage your network by crafting an elevator pitch about why you think you're great for this role. List three people whom you can share your pitch with: one who can give you honest but tough feedback, one who can knows your strengths, and one who may know the role.

8. Background Research: What's missing from the job description that is still very important to you? Get early intel on things like benefits and company culture through tools such as Glassdoor and LinkedIn.

9. Understand the Customer: Once you've applied, you'll likely have a chance to find out who is the hiring manage and maybe even who is on the interview panel. Craft questions for each panelist that you can identify.

10. Prep your interview: See the structure, organize your strategy for any technical sessions, and review the STAR method for answering behavioral questions.

Find the right Data Scientist role for YOU by focusing first on what you have to offer and what you want in a next role. Then check your assumptions and call out your capabilities. Leverage your network and tools to gather insights that aren't on the job description. Finally, customize your questions and response style to the format and participants of the interview loop.

How to Predict The Future: Powering Decision Making Through ML Forecasting

Session - kelley hall

In sales, everyone has their own secret sauce for how they do their business. Especially when it comes to forecasting their sales for a given quarter, leading to siloed information and making it impossible to determine root causes to under or over-forecasting. So how can you use machine learning to demystify the forecasting process and build consistency and confidence in data?

In this talk, I will share my own experience working for in Sales Operations to develop a forecasting model. I will address how to set up a forecasting problem and model (specifically using the GluonTS package developed by AWS), common pitfalls, and how I used data visualization in Tableau to provide actionable insights. Most importantly I'll share how we were able to get non-technical users bought in and confident with our model, making the model a part of their daily routine.

What's Next: Navigating the Career Path to Becoming a Staff/Principal Data Scientist

Session - Iswarya murali

"What got you here won't get you there."

Promotions are tricky. A Staff/Principal role in engineering companies involves broad impact across the organization, strong technical leadership and being a force multiplier in the team. A promotion to this level can be challenging in the Data Science field, which is more specialized and niche compared to SoftwareEngineering, where Principal roles are rarer and not as well-defined. In this talk I want to share my learnings from my own experience about the skills needed to be an effective Staff/Principal DataScientist – about how to create exponential impact across the organization instead of doing more of the same work, finding your niche, developing technical and business acumen, communicating effectively at the leadership level, and most importantly, advocating for yourself.

Using Multi-Modal Data Sources to Model Predictive Outcome

Workshop - sanghamitra deb

In the past decade, Machine Learning has touched different aspects of our life such as education, healthcare, social network, entertainment, e-commerce and so on. Most tech companies collect huge quantities of data on content, customers, products and their interactions, to mention a few. In many applications, input signals come with multiple modalities - there could be text, images, video, audio, etc. Ideally, a predictive model should be able to leverage all these modalities, together with other structured data to come up with rich representations that ultimately power meaningful consumer experiences. It is possible to have image, speech, text and structured data that can be used to create a predictive solution such as content quality, churn, search or recommendations.

In this tutorial I will present a deep learning framework where multiple modes of data is used as input for a specific predictive task. For text data, embeddings from language models are used as initial layers followed by CNN, LSTM or transformers. Information from images are extracted in the form of embeddings, and concatenated with text data to enhance predictive features. Once all the data are combined there is a final classification layer for the predictive outcome. In some cases there can also be audio (podcasts, recorded presentations, voice components for videos) or video data (movies, educational videos, videos for ads). This information can also be added to the feature space of predictive models. Once all the data are combined there is a final classification layer for the predictive outcome.

In this tutorial I will discuss building a generalized multi-modal predictive model.
