What is Machine Learning? â–Ş Machine learning Using Spark-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.

Into to Machine Learning Using Spark • 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. Copyright @ 2015 Learntek. All Rights Reserved.

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.

Prerequisites : â–Ş Prior understanding of exploratory data analysis and data visualization will help immensely in learning machine learning concept and This
include basic
applications.
statistical technique for data analysis. Having some
knowledge of R programming or some Python packages like sci-kit, numpy will be useful. However , we are going to cover basic statistics technique as part of this course before going deep into machine learning . This will help
everyone to gain maximum from this course.
