Python use case – Resampling time series data (Upsampling and downsampling) – SQL Server 2017

Resampling time series data in SQL Server using Python’s pandas library In this post, we are going to learn how we can use the power of Python in SQL Server 2017 to resample time series data using Python’s pandas library. Sometimes, we get the sample data (observations) at a different frequency (higher or lower) than […]

What is Machine learning and why is it gaining so much popularity?

Well now a days everyone seems to be talking about machine learning and its applications/uses, but have we ever thought how all of a sudden ML has become so popular? If I tell you that work on AI started way back in 1950 and Machine learning started to grow rapidly in 1990, what has suddenly

Tidy Data in Python – First Step in Data Science and Machine Learning

Most of the Data Science / Machine Learning projects follow the Pareto principle where we spend almost 80% of the time in data preparation and remaining 20% in choosing and training the appropriate ML model. Mostly, the datasets we get to create Machine Learning models are messy datasets and cannot be fitted into the model
