Hadoop is a framework for distributed storage and processing of large datasets. It operates by breaking down massive files into smaller data blocks and distributing them physically across a cluster of standard computer servers.

In artificial intelligence and machine learning, a hallucination occurs when a Large Language Model (LLM) or generative AI system produces text, data, or information that is factually incorrect, nonsensical, or entirely fabricated, while presenting it as an accurate output.

It is an unsupervised machine learning algorithm used to group unlabeled data points into distinct categories, or clusters

Hyperparameters refer to parameters set before training a model, such as learning rate or number of layers.

A Hyperplane is a geometric concept representing a flat subspace whose dimension is exactly one less than the dimension of its surrounding, ambient space.

A process to determine if a hypothesis is statistically significant. It involves comparing a baseline assumption about a population to observed sample data.
