Always On availability

Always On availability refers to the ability of a system to remain operational and accessible at all times, even during planned maintenance or unexpected outages.

Machine Learning (ML)

AUC (Area Under The Curve) and ROC (Receiver Operating Characteristics)

In binary classification issues, the metrics AUC (Area Under the Curve) and ROC (Receiver Operating Characteristics) are frequently employed. AUC is a numerical metric that measures the performance of the classifier, whereas ROC is a graphical plot that shows the performance of a binary classifier.

System Design

Database Clustering

Database clustering is a technique used to increase the availability, scalability, and reliability of a database system.

Natural Language Processing (NLP)

Sentiment analysis with NLP

Sentiment Analysis is the method of locating and extracting subjective information from text data. It entails determining whether the emotional bias of a text is positive, negative, or neutral by looking at its contents.
