Product Description

What is Machine Learning?

Machine learning-Spark MLlib is an application of artificial intelligence (AI) that provides systems the ability to automatically learn and improve from experience without being explicitly programmed. Machine learning focuses on the development of computer programs that can access data and use it learn for themselves.
The process of learning begins with observations or data, such as examples, direct experience, or instruction, in order to look for patterns in data and make better decisions in the future based on the examples that we provide. The primary aim is to allow the computers to learn automatically without human intervention or assistance and adjust actions accordingly.

Into to Spark MLlib

MLlib is  Spark’s machine learning (ML) library. Its goal is to make practical machine learning scalable and easy. At a high level, it provides tools such as:

ML Algorithms: common learning algorithms such as classification, regression, clustering, and collaborative filtering

Featurization: feature extraction, transformation, dimensionality reduction, and selection

Pipelines: tools for constructing, evaluating, and tuning ML Pipelines

Persistence: saving and load algorithms, models, and Pipelines

Utilities: linear algebra, statistics, data handling, etc.

Tools

This course will be delivered using Scala and PYTHON API. For explaining statistical concept, R language will also be using. Visualization part will be covered using Bokeh/ggplot library.
