Categorizing financial transactions for personal finance management at Yolt

By Alexander Backus, Lead Data Scientist at Yolt and consultant at BigData Republic

Yolt, a fintech venture of ING Bank, is continuously improving their financial transaction categorization engine to provide app users with a comprehensive overview of income and spendings. But how to approach this seemingly clear-cut classification task and what are the key considerations? In this talk, Alexander will discuss all aspects, from business requirements to algorithms, starting with a simple model and moving on to label embedding neural networks.


Deep image matching

Marijn Lems ( will take you through the process of training the deep learning model that they use for image matching.

We discuss some fun and interesting challenges during data collection, hand labeling, cleaning, preparation, modelling and operationalization. Then we will dig deeper in what type of CNN architectures for image matching proved to work and how we optimized hyper parameters. We will look into deep representation learning and cover sampling procedures that boosted image matching performance.

ImageLink (a product of replaces QR codes using image matching technology. Instead of scanning a QR code, you scan images. A new and exciting way of activating your (printed) assets.
