For about a year now, the support team of one of our high-loaded instruments has been using an ML-system of our own development, the Problem Detection Platform (PDP). This service can analyze logs and automatically classify errors. As a result, the support team does not get a bunch of raw data from the logs, but rather information that can be handled quickly and conveniently. Machine learning is part of artificial intelligence technologies that allow analytical systems to see patterns in raw data. It is used for recognizing objects in photos and videos, combating security threats and financial fraud, balancing traffic in telecommunications infrastructures, etc.
