Danijel Temraz is Senior Software Engineer in Infobip working on grey routes detections and on Customer Support Service product.
Grey route is a business fraud taking huge chunks of revenue from telecom and likewise telecom partners. Danijel designed and implemented solution with applied graph theory, computer science and machine learning which in real time autonomously blocks sim cards participating in these frauds. He also implemented machine learning platform that we use for other problems.
Danijel is mentoring Princeton University Algorithms, Part I MOOC at Coursera platform.
In machine learning projects focus is usually spent in achieving ‘perfect’ bias-variance trade-off. While critical for success, in order to have truly useful machine learning model which can work with hundreds of millions of daily transactions and make autonomous decisions, we should not forget other tools that we have at our disposal, such as domain knowledge, rules and computer science. This is something that we try to keep in mind for our machine learning projects, good solution is the one that solves the problem efficiently.
In Infobip, we see the value and are willing to invest into data science, machine learning and embrace scientific method of solving problems. We are still new in the area but making progress every day. As we say, we are just starting
