ABOUT THIS EVENT

 * 1 hour
 * Mobile eTicket

Data Phoenix team invites you all to our upcoming "The A-Z of Data" webinar
that’s going to take place on April 27 at 16.00 CET.

 * Topic: "Evaluating XGBoost for balanced and imbalanced datasets"
 * Speaker: Gissel Velarde, Senior Data Scientist at Vodafone
 * Language: English
 * Participation: free (but you’ll be required to register)

ABOUT THE SPEAKER AND TOPIC

Globally, fraud accounts for more than 2 percent of the total revenue loss in
the telecommunication sector. Fraud detection is not a trivial problem:
fraudsters try different tactics to simulate customers' behavior, constantly
invent new ways to fool the system, and might appear sporadically. The project
could help prevent equipment theft, reselling, and commission fraud among the
many types of fraud scenarios. Dr. Gissel Velarde will present an AI-based Fraud
Detection System, including several experiments with XGBoost, demonstrating how
efficient machine learning models can automatically detect fraud cases depending
on the data used.

Gissel Velarde

Dr. Gissel Velarde holds a Ph.D. in Computer Science and Engineering from
Aalborg University for her work on machine learning-based models to analyze
perceptual applications. Dr. Velarde has received several prizes and awards as
an engineer and data scientist. In 2021, she received a teaching award at UPB
for her lecture: Selected Topics in Artificial Intelligence. In 2022 and 2023,
she received Vodafone Start Awards for contributing to AI Strategies and the
execution of experiments that generated knowledge to develop a robust detection
system. Currently, she is a Senior Expert Data Scientist at Vodafone, leading
the risk assessment project from the AI and machine learning side.
