Data Preparation — Collect data, Understand features 2. Visualize Data — Rolling mean/ Standard Deviation— helps in understanding short-term trends in data and outliers. The rolling mean is an average of the last ’n’ data points and the rolling standard deviation is the standard deviation of the last ’n’ points.

This helps with data preparation and feature engineering tasks and model training and deployment automation. Moreover, they require a pre-determined number of topics, which was hard to determine in our data set. The approach uses three sequential BERTopic models to generate the final clustering in a hierarchical method.

Unsupervised Learning Unsupervised learning involves training models on data without labels, where the system tries to find hidden patterns or structures. This type of learning is used when labelled data is scarce or unavailable. Data Transformation Transforming data prepares it for Machine Learning models.
