FINRA: Be a Hero - Use Data Analytics to Catch Financial Bad Guys! (4)

Are you ready to become a crime fighter in today’s rapidly growing world of electronic data? Believe it or not, technology can be a super power to help establish relationships between “bad guys” and the people who associate with them. As Superman says, “There is a right and a wrong in the universe, and the distinction is not that hard to make.” Can you identify an entire “gang” from the wide array of data available? Can you spot different types of relationships across the entities, events, and locations? Can you strengthen or weaken those connections by using your super powers to summon more data or different data?
Your Challenge:
With great power comes great responsibility - identify the “villians” as well as the types of relationships they have with other entities found in the data sets provided. We encourage you to use additional data sources to uncover connections between entities in the data that may have no apparent connection in the initial comparison. Data Sets will be made available once the Hackathon begins.
Suggested open source tools:
Apache Stanbol (we highly recommend you start with that library first unless you have previous experience with the other two),
Stanford Entity Resolution Framework, and
$3000 in cash equivalent prizes to winning team(s) to be split evenly among team members

Intuit: College Student Prosperity Case (2)

Provide a solution or application to help a college student become more prosperous. We will select one team to win our challenge and each member of the winning team member will receive an Echo Dot!

Stanley Black & Decker: Storage Solutions Augmented Reality

Build a Storage Solutions configurator that can work in augmented reality. We’re trying to aid our sales team to show clients how the product will look in their specific work space so they can make a buying decision. Customers are interested in how much room the product(s) will take up, and how it looks next to existing equipment.
Here is what we have today: https://www.storageconfiguration.com/lista/. Once a user creates their cabinet, we'd like them to see what one or multiple cabinets look like in their space using Augmented Reality. With the option to reorder the cabinets, and put them next to live objects. The most important feature is to have accurate height, width, and depth showing within the Augmented Reality so customers get an accurate representation of the product they are looking to purchase. Customers should also be able to rotate the product, so it can stand against a wall, or sit in the center of an area. Users should be able to put multiple products next to each other and reorder them, so move-ability is key. Some users may also want to leave spaces in between each product, so having full control is important. Typically, sales representatives will go onsite to a user to explain product options, so having this accessible via a tablet or mobile phone is preferred.
Prize: Bose bluetooth wireless headphones for each person on the winning team.

Mirum and JWT: Can a Computer Hear How You Feel? Seeing the emotion in IM and voice (4)

Broad Challenge: Routinely teams and brands communicate through IM or voice. Whether it is in email exchanges, chat tools (Microsoft Teams / Slack), chat bots (Facebook Messenger) and Voice interfaces (Alexa, Google Assistant) we need our computers to understand the emotion underlying the communication. With international teams, or with teams coming from diverse backgrounds, it is easy to misunderstand the emotional state of the team member or customer. Our goal is to score and visualize the emotional tone of a conversation so teams can perform better and brands can react accordingly.

Data Set: We will provide a set of 5 individual conversations, 2 in voice and 2 in text

Tools: Open API for assessing emotional sentiment in voice communication or text communication https://medium.com/@sifium/top-five-emotional-sentiment-analysis-apis-116cd8d42055

Output: You’re challenge is to be able to score the emotional tone of each speaker (ie anger, joy, fear) and also if possible language tones (analytical, confident) and social tones (openness, agreeableness). A home run allows us to record a conversation and display the emotional state of the two parties speaking. We would like display on a mobile app (mobile webpage is fine) or to an i-frame for display on a website.
TOP TEAM WINS: Google Home Minis (1 each for up to 4 participants); Internal presentation to Mirum's CEO and CTO; Agency Introductions; External promotion including social channels and blog. 3 ADDITIONAL TEAMS WIN: Agency Introductions; External promotion including social channels and blog.
