Jai Bansal, Senior Manager, Data Science at Aetna
This talk describes an internal data product called Member Embeddings that facilitates modeling of member medical journeys with machine learning.
Medical claims are the key data source we use to understand health journeys at Aetna. Claims are the data artifacts that result from our members' interactions with the healthcare system. Claims contain data like the amount the provider billed, the place of service, and provider specialty. The primary medical information in a claim is represented in codes that indicate the diagnoses, procedures, or drugs for which a member was billed. These codes give us a semi-structured view into the medical reason for each claim and so contain rich information about members' health journeys. However, since the codes themselves are categorical and high-dimensional (10K cardinality), it's challenging to extract insight or predictive power directly from the raw codes on a claim.
To transform claim codes into a more useful format for machine learning, we turned to the concept of embeddings. Word embeddings are widely used in natural language processing to provide numeric vector representations of individual words.
We use a similar approach with our claims data. We treat each claim code as a word or token and use embedding algorithms to learn lower-dimensional vector representations that preserve the original high-dimensional semantic meaning.
This process converts the categorical features into dense numeric representations. In our case, we use sequences of anonymized member claim diagnosis, procedure, and drug codes as training data. We tested a variety of algorithms to learn embeddings for each type of claim code.
We found that the trained embeddings showed relationships between codes that were reasonable from the point of view of subject matter experts. In addition, using the embeddings to predict future healthcare-related events outperformed other basic features, making this tool an easy way to improve predictive model performance and save data scientist time.

Data Con LA 2022 - Collaborative Data Exploration using Conversational AIData Con LA
Anand Ranganathan, Chief AI Officer at Unscrambl
Conversational AI is getting more and more widely used for customer support and employee support use-cases. In this session, I'm going to talk about how it can be extended for data analysis and data science use-cases ... i.e., how users can interact with a bot to ask analytical questions on data in relational databases.
This allows users to explore complex datasets using a combination of text and voice questions, in natural language, and then get back results in a combination of natural language and visualizations. Furthermore, it allows collaborative exploration of data by a group of users in a channel in platforms like Microsoft Teams, Slack or Google Chat.
For example, a group of users in a channel can ask questions to a bot in plain English like ""How many cases of Covid were there in the last 2 months by state and gender"" or ""Why did the number of deaths from Covid increase in May 2022"", and jointly look at the results that come back. This facilitates data awareness, data-driven collaboration and joint decision making among teams in enterprises and outside.
In this talk, I'll describe how we can bring together various features including natural-language understanding, NL-to-SQL translation, dialog management, data story-telling, semantic modeling of data and augmented analytics to facilitate collaborate exploration of data using conversational AI.

Super Bowl Ad cost $7 million and each year a few Super Bowl ads go viral. The traditional A/B testing does not predict virality. Some highly shared ones reach over 60 million organic views, which can be more valuable than views on TV. Not only are these voluntary, but they are typically without distraction, and win viewer engagement in the form of likes, comments, or shares. A Super Bowl ad that wins 69 million views on YouTube (e.g., Alexa Mind Reader) costs less than 10 cents per quality view! However, the challenge is triggering virality. We developed a method to predict virality and engineer virality into Ads.
1. Prof. Gerard J. Tellis and co-authors recommended that advertisers use YouTube to tease, test, and tweak (TTT) their ads to maximize sharing and viewing. 2022 saw that maxim put into practice.
2. We developed viral Ads prediction using two scientific models:

Data Con LA 2022 - Early cancer detection using higher-order genome architectureData Con LA
My (Angela) Chung, Data Enthusiast, San Jose State University
Cancer is a complex disease which requires interactions between cell-intrinsic alterations and tumor microenvironment. The connection between epigenetics and genomic structure plays a key role in chromatin interactions and enhancer-promoter communications for transcriptional activities. Alterations of these components in oncogenic signaling pathway potentially cause cancer cell-intrinsic changes and inappropriate instructions to normal cell cycles, leading to abnormal cell growth.
' Topologically associating domains (TADs) and A/B compartments are the main structures of higher-order chromatin structure. These contact domains, chromatin states, super-enhancers, and histone modifications together regulate transcription and gene expression for normal/abnormal cell cycles.
' Several bioinformatics tools were utilized ' FANC for processing raw FASTQ data to Hi-C contact matrices, JuicerTools for obtaining the locations of contact domains on the entire genome, and CoolBox for visualizing chromatin contacts in different cell lines.
' High-resolution chromatin contacts showed dynamic interactions among chromosomal regions in different cell lines.
' Qualitative and quantitative features were comprehensively engineered from 3D chromatin folding and epigenetic regulators using available packages (scikit learn, pytorch, pandas, numpy, matplotlib, etc.).
' XGBoost multi-class classifier achieved the highest accuracy of 80.90% in classifying normal and cancer cell lines based on chromatin interactions, followed by Random Forest at 73.76% and TabNet classifier at 70.00%.
Data Con LA 2022 - Open Source Large Knowledge Graph FactoryData Con LA
Russell Jurney, Founder, Graphlet AI
The knowledge graph and graph database markets have long asked themselves: why aren't we larger? The vision of the semantic web was that many datasets could be cross-referenced between independent graph databases to map all knowledge on the web from myriad disparate datasets into one or more authoritative ontologies which could be accessed by writing SPARQL queries to work across knowledge graphs. The reality of dirty data made this vision impossible. Most time is spent cleaning data which isn't in the format you need to solve your business problems. Multiple datasets in different formats each have quirks. Deduplicate data using entity resolution is an unsolved problem for large graphs. Once you merge duplicate nodes and edges, you rarely have the edge types you need to make a problem easy to solve. It turns out the most likely type of edge in a knowledge graph that solves your problem easily is defined by the output of a Python program using the machine learning. For large graphs, this program needs to run on a horizontally scalable platform PySpark and extend rather than be isolated inside a graph databases. The quality of developer's experience is critical. In this talk I will review an approach to an Open Source Large Knowledge Graph Factory built on top of Spark that follows the ingest / build / refine / public / query model that open source big data is based upon.

David Sarabia, Founder/ CEO at inRecovery & Sig Narvaez, Executive Solution Architect at MongoDB
As a bullied kid, I found refuge in computers and taught myself to code at 8. By 26, I had two successful tech exits and moved to NYC. A weekend party habit led to daily drug use and a spiral to heroin and homelessness. In 2016, after a friend�s overdose woke me up. I checked myself into rehab and quickly realized I was there for a bigger purpose.
Healthcare is very broken. From legacy systems, inefficiencies, and poor customer experience. What if we could dramatically improve care models by leveraging data, personalizing treatment, and creating beautiful patient experiences?
Ever worked in an industry that felt antiquated? Learn how we use MongoDB to transform addiction care and help people thrive in life!

Data Con LA 2022 - Event Sourcing with Apache Pulsar and Apache QuarkusData Con LA
David Kjerrumgaard, Developer Advocate, StreamNative
I believe that event-sourcing is the best way to implement persistence within a microservices architecture, but it hasn't always been the easiest solution to implement. In this talk, I will demonstrate how these two exciting technologies can be combined into one killer stack that simplifies event sourcing development. I will outline how to use DDD and CQRS concepts as a guide for developing an event sourcing food-delivery application based on Apache Pulsar and Quarkus that is 100% cloud native. Throughout this talk, I will demonstrate several different event sourcing design patterns across multiple microservices to feed multiple real-time dashboards that provide driver location tracking, and heatmaps. I will also highlight some patterns for using an event streaming platform as your event store.

Data Con LA 2022 - Early cancer detection using higher-order genome architectureData Con LA
My (Angela) Chung, Data Enthusiast, San Jose State University
Cancer is a complex disease which requires interactions between cell-intrinsic alterations and tumor microenvironment. The connection between epigenetics and genomic structure plays a key role in chromatin interactions and enhancer-promoter communications for transcriptional activities. Alterations of these components in oncogenic signaling pathway potentially cause cancer cell-intrinsic changes and inappropriate instructions to normal cell cycles, leading to abnormal cell growth.
' Topologically associating domains (TADs) and A/B compartments are the main structures of higher-order chromatin structure. These contact domains, chromatin states, super-enhancers, and histone modifications together regulate transcription and gene expression for normal/abnormal cell cycles.
' Several bioinformatics tools were utilized ' FANC for processing raw FASTQ data to Hi-C contact matrices, JuicerTools for obtaining the locations of contact domains on the entire genome, and CoolBox for visualizing chromatin contacts in different cell lines.
' High-resolution chromatin contacts showed dynamic interactions among chromosomal regions in different cell lines.
' Qualitative and quantitative features were comprehensively engineered from 3D chromatin folding and epigenetic regulators using available packages (scikit learn, pytorch, pandas, numpy, matplotlib, etc.).
' XGBoost multi-class classifier achieved the highest accuracy of 80.90% in classifying normal and cancer cell lines based on chromatin interactions, followed by Random Forest at 73.76% and TabNet classifier at 70.00%.
Data Con LA 2022 - Open Source Large Knowledge Graph FactoryData Con LA
Russell Jurney, Founder, Graphlet AI
The knowledge graph and graph database markets have long asked themselves: why aren't we larger? The vision of the semantic web was that many datasets could be cross-referenced between independent graph databases to map all knowledge on the web from myriad disparate datasets into one or more authoritative ontologies which could be accessed by writing SPARQL queries to work across knowledge graphs. The reality of dirty data made this vision impossible. Most time is spent cleaning data which isn't in the format you need to solve your business problems. Multiple datasets in different formats each have quirks. Deduplicate data using entity resolution is an unsolved problem for large graphs. Once you merge duplicate nodes and edges, you rarely have the edge types you need to make a problem easy to solve. It turns out the most likely type of edge in a knowledge graph that solves your problem easily is defined by the output of a Python program using the machine learning. For large graphs, this program needs to run on a horizontally scalable platform PySpark and extend rather than be isolated inside a graph databases. The quality of developer's experience is critical. In this talk I will review an approach to an Open Source Large Knowledge Graph Factory built on top of Spark that follows the ingest / build / refine / public / query model that open source big data is based upon.

Embedding medical journeys with machine
learning to improve member health at Aetna
Core Contributors: Jai Bansal, Matt Churgin, Reed Peterson, Evan Lyle
2. Agenda
1. Messaging members to improve health
2. What are embeddings?
3. How can embeddings support an insurer’s work?
4. Evaluation and applications
4. Insurers can impact members through behavior change campaigns
• These campaigns can promote healthy and cost-effective
choices for members
• Sample Process
• Identify domain where members can benefit from targeted communication.
Review concept with relevant business partners, clinicians, and legal team
• Design outreach with multi-disciplinary group. Outreach channels could
include email, direct mail, and text message.
• Implement outreach using a randomized control trial framework and
measure results
• Call-To-Action Examples: an insurer could message about
• Preventive care: encourage members to utilize preventive care
benefits to improve their long-term health
• Medication adherence: encourage members to follow prescribed
medication regimes to improve long-term health
• Preferred site of care: encourage members to seek routine services
at in-network providers to reduce out-of-pocket medical spend
Illustrative example of messaging
5. Campaigns can use predictive models to inform targeting. Medical claims data
can be used to create model features.
• Predictive models might be used to identify members that
have a high likelihood of responding to messaging or
developing a preventable condition or illness.
• Insurers could use medical claims to build models. Medical
claims are artifacts generated from members’ interactions
with providers.
• One of the key pieces of data contained in claims are
medical codes
• ICD codes indicate a member’s diagnosis
• CPT codes indicate any procedure a member underwent
• GPI codes indicate member prescriptions
• There are >10K ICD codes
Sample ICD (Diagnosis) Codes

A00.9 Cholera, unspecified
Z86.16 Personal history of COVID-19

8. Embeddings capture information about the features they are built from
A famous example from text embeddings is that embeddings should capture relationships between royal
and non-royal as well as man and woman.

Embeddings should preserve existing
relationships
10. Medical codes contained in claims are a rich feature source, but cannot be used
in models in their raw form
• Diagnosis, procedure, and prescription codes represent
granular data about a member’s healthcare journey. But
they can’t be used in models in their raw form.
• Could one-hot encoding solve the issue? Not really
• There are >10K diagnosis codes, so one-hot encoding would result in
extremely sparse vectors
• One-hot encoded vectors also would not support comparison of codes
(but embeddings would)
• Embedding medical codes can provides a way to use
valuable claims information
• There’s also another opportunity here: since all medical
claims use these codes, it’s possible to build an automated
feature generation tool with code representations

11. Feature engineering is a critical part of building predictive models and takes
substantial data scientist time and effort
• Feature engineering (FE), including data collection and cleaning, takes 80% of DS time during model
development
• Models often use similar features so a lot of individual FE is duplicative. If a typical DS spends 30% of their
time on FE and has an all-in cost of $200K, then $60K is being spent on FE per DS per year.
• With individual DSs doing custom FE, model features may miss important information. By creating
standardized, comprehensive features, adding embedding features could improve model recall by 10% on
average.
Model Development Feature Engineering: 80%
Overall DS Time Feature Engineering: 30%
12. Embeddings can be trained using de-identified member medical claim data
Members’ de-identified
medical history
is recorded in ICD +
procedure + GPI codes.
Sample ICD Codes
• Jan 1: H60.33
• Feb 1: L20.82
• Mar 1: M16.30
The codes can then be fed into an
embedding training algorithm (for
example, word2vec or GloVe). Each
code is a token and a member’s series
of code would be treated as a
“sentence.”
(Made-up) ICD Embeddings
• H60.33 : [1.3, 2.4, …, 3.2]
• L20.82 : [9.3, 1.2, …, 8.3]
• M16.30 : [4.5, 7.6, …, 2.6]
Embeddings would be trained using
claims data for a significant population
of members to the extent permitted by
law and client contracts. A member’s
code embeddings over a user-defined
time period should be averaged to
obtain the final member-level
embedding.
14. Plotting diagnosis codes in 2D yields reasonable spatial relationships based on
domain knowledge
• >10K unique ICD (diagnosis)
codes
• Each point is colored by ICD
group and represents one ICD
code’s embedding
• Codes in the same group and
related groups tend to cluster
together
• Embeddings preserve our
qualitative expectation of
relationships between codes,
with the added benefit that these
relationships are quantified

15. Plotting procedure codes in 2D can reveal interesting differences between members
• The plots below illustrate insights that can be derived from visualizing members’ embeddings
• Each point represents a member’s averaged procedure code embeddings
• Embeddings allow identification and comparison of members based on medical utilization
Medicare and Commercial members undergo
different procedures
Procedures are generally similar across gender,
with a few important exceptions
Members of different ages undergo different
procedures
Any data contained in this slide is used to the extent permitted by law and client contracts
16. Using embeddings as features provides a quantitative evaluation method
• Comparing embedding features
to simple group counts for a
variety of medical events is a
quantitative way to evaluate the
effectiveness of embedding
features
• For most events, embedding
features outperform simple
count features
• Some medical events are more
predictable overall than others
Any data contained in this slide is used to the extent permitted by law and client contracts
17. Medical code embeddings can add value in two main ways
Value Add 1: Embedding features provide an easy way to improve
performance of existing models.
Value Add 2: Embeddings can be used to quickly train new models
with minimal feature engineering.
18. Potential Next Steps for Embeddings
1. Track internal usage via installs and/or monthly active users
2. Test new embedding algorithms
3. Explore embeddings for other types of medical codes
4. Consider more applications for embeddings, for example member clustering
