Big Data Technologies

Big Data Technologies

Big Data refers to datasets that are too large and complex for traditional data processing applications to handle efficiently. It is characterized by the 5 Vs: Volume, Velocity, Variety, Veracity, and Value. Volume refers to the vast amount of data generated, Velocity refers to the speed at which data is generated and processed, Variety refers to the different types of data (structured, semi-structured, and unstructured), Veracity refers to the reliability and quality of the data, and Value refers to the…

Introduction to Machine Learning

Introduction to Machine Learning

Machine Learning (ML) is a subfield of artificial intelligence (AI) that focuses on the development of algorithms and models that allow computers to learn from data and make predictions or decisions without being explicitly programmed for every task. The primary goal of machine learning is to develop algorithms that can learn patterns and relationships from data and use this knowledge to make predictions or decisions on new, unseen data. Imagine a dataset containing information about students’ attendance records, study hours…
