Apache Spark MLlib

Apache Spark was developed in Bekeley’sAMPLab, at California University. It is known as an open-source cluster-computing framework. Apacke Spark provides the application programming interface to programmers centred on data structure known as Resilient Distributed Dataset (RDD).
Apache Spark requires a distributed storage system and a cluster manager. Spark supports Apache Mesos, Hadoop YARN, and standalone for cluster management. Spark may interface with an immense variety for -distributed storage. Such variety consists of Kudu, Amazon S3, OpenStack Swift, Cassandra, MapR File System, and Hadoop distributed File System etc.

What is Apache Spark MLlib?

MLlib here is an abbreviation for Machine Learning library. Its prime target is to make practical machine learning easy and scalable. At an expert level, it provides below mentioned tools-

Algorithms

Gradient-boosted trees, random forests, and decision trees
Sequential pattern mining, association rules, frequent item-sets
Latent Dirichlet Allocation (LDA) in Topic Modelling
Gaussian Mixtures, K-Means in Clustering
Alternating Least squares in Recommendation
Survival regression, generalized linear regression etc. in Regression
Naïve Bayes, logistic regression in Classification

Loading and saving of pipelines and models
Hyper parameter tuning and model evaluation
Construction of ML pipeline
Feature transformations like hashing, normalization, and standardization etc.
Hypothesis testing, summary statistics, distributed linear algebra such as PCA, SVD etc.

Easy Deployment Adds More Comfort

If you already have Hadoop 2 cluster, then you don’t require any pre-installation to run Spark and MLlib. Spark is quite easy to run on Mesos, EC2, or standalone etc.

Classification

It refers to supervised ML (Machine Learning) algorithms that elect the input as belonging to one of several pre-defined classes. Classification data is enriched with labelled data such as non-fraud/fraud, or non-spam/spam etc. ML assigns a new class or label to new data. They can elaborate about the Apache Spark MLlib quite efficiently to you and it will help you enhance your knowledge. Along with learning they will also help you in practical execution as well.

Below are some of its practical examples-

Detection of email-spam

Credit card and other identical fraud detection

Clustering in Apache Spark MLlib

Algorithm groups the objects into different categories after analysing resemblances between the input examples. Some of its practical uses are-

Test Categorization

Anomaly Detection

Customers’ Grouping

Grouping of Search Results

Algorithm groups the objects into different categories after analysing resemblances between the input examples. Some of its practical uses are-

Collaborative Filtering (CF)

CF algorithms recommend items as per the preference information from different users. Approach of Collaborative Filtering relies on similarity i.e. users who like identical items in the past will like the identical items in future as well. Its main aim is to pull the preference data from users and creating a proficient model for predictions and recommendations.

Decision Trees

They help in creating a prediction model that predicts label or class based on plenty of input features. Decision tress perform by evaluating an expression carrying a feature at every node choosing a branch to next node as per the answer. When anyone of the following condition is met, the recursive tree construction stops at a node-

Speed Benefits and Completeness of RDD in MLlib

In some cases, it is quite beneficial to get back to the vintage RDD-based spark.mllib package for such functions that haven’t been ported yet to newer spark.ml package. The ability of Spark Statistics Library to generate a correlation matrix in a single pass and for more precise model evaluation functions, make RDD implementation a more productive choice. You can improve your performance by using RDD-based spark.mllib correlation matrix function. DataFrame based spark.ml for evaluating correlation between any 2 columns is straightforward and fast.
Spark has registered a considerable growth in market in the recent past. There are plenty of approaches in getting started with Spark. Primary interfaces consist of Spark SQL (Datasets/DataFrames), and Resilient Distributed Databases (RDDs). RDDs are the authentic API shipped with Spark 1.0 where the data is passed as opaque objects.
