Hackathon: Who is better to spot generated image?
The online hackathon by Digital Leader was held from 19.10 to 27.11.2020. I have shown that a trained neural network better distinguish generated face images that human. As a result, I took 4th place and won swag prizes.

Graph classification by computer vision
Graph analysis nowadays becomes more popular, but how does it perform compared to the computer vision approach? We will show while the training speed of computer vision models is much slower, they perform considerably well compared to graph theory.

Anomaly detection in time series with Prophet library
Anomaly detection problem for time series can be formulated as finding outlier data points relative to some standard or usual signal. While there are plenty of anomaly types, we’ll focus only on the most important ones from a business perspective, such as unexpected spikes, drops, trend changes and level shifts by using Prophet library.
