Semantic Chunker is a lightweight Python package for semantically-aware chunking and clustering of text. It’s designed to support retrieval-augmented generation (RAG), LLM pipelines, and knowledge processing workflows by intelligently grouping related ideas. Traditional chunking methods for LLM pipelines often rely on fixed-size windows or naive text boundaries, which can fragment meaning, split u
K-means clustering is a type of unsupervised learning when we have unlabeled data (i.e., data without defined categories or groups). Clustering refers to a collection of data points based on specific similarities. K-Means AlgorithmK-means aims to find groups in the data, with the number of groups represented by the variable K. Based on the provided features, the algorithm works iteratively to assi
When we cluster things, we put them into groups. In Machine Learning, Clustering is the process of dividing data points into particular groups. One group will have similar data points and differentiate from those with other data points. It is purely based on the patterns, relationships, and correlations in the data. Clustering is a form of Unsupervised Learning. Let’s quickly recap the definition

If you read the "An Introduction to Clustering" article, you will know that Hierarchical Clustering is a type of Connectivity model in Machine Learning. To recap, Connectivity Models are based on the fact that data points in the same data place have similarities. What is Hierarchical Clustering?Hierarchical Clustering is an algorithm that groups similar data points into clusters. Hierarchical Clus
