DataPreparation — 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 datapreparation 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.
DataPreparation for AI Projects Datapreparation is critical in any AI project, laying the foundation for accurate and reliable model outcomes. This section explores the essential steps in preparingdata for AI applications, emphasising data quality’s active role in achieving successful AI models.
Datapreparation and loading into sequence store The initial step in our machine learning workflow focuses on preparing the data. Following Nguyen et al , we train on chromosomes 2, 4, 6, 8, X, and 14–19; cross-validate on chromosomes 1, 3, 12, and 13; and test on chromosomes 5, 7, and 9–11.
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 dataprepares it for Machine Learning models.

Applications : Stock price prediction and financial forecasting Analysing sales trends over time Demand forecasting in supply chain management Clustering Models Clustering is an unsupervised learning technique used to group similar data points together. Popular clustering algorithms include k-means and hierarchical clustering.
Key steps involve problem definition, datapreparation, and algorithm selection. Data quality significantly impacts model performance. UnSupervised Learning Unlike Supervised Learning, unSupervised Learning works with unlabeled data. The algorithm tries to find hidden patterns or groupings in the data.
A traditional machine learning (ML) pipeline is a collection of various stages that include data collection, datapreparation, model training and evaluation, hyperparameter tuning (if needed), model deployment and scaling, monitoring, security and compliance, and CI/CD.
