Map Reduce In Machine Learning

In a MapReduce program, Map() and Reduce() are two functions. The Map function performs actions like filtering, grouping and sorting. While Reduce function aggregates and summarizes the result produced by map function. The result generated by the Map function is a key value pair (K, V) which acts as the input for Reduce function.

Basic Steps To Perform Map Reduce

Input Splits:

It is a fixed-size pieces called input splits Input split is a chunk of the input that is consumed by a single map


In this phase data in each split is passed to a mapping function to produce output values. In our example, a job of mapping phase is to count a number of occurrences of each word from input splits (more details about input-split is given below) and prepare a list in the form of <word, frequency>


This phase consumes the output of Mapping phase. Its task is to consolidate the relevant records from Mapping phase output. In our example, the same words are clubed together along with their respective frequency.


In this phase, output values from the Shuffling phase are aggregated. This phase combines values from Shuffling phase and returns a single output value. In short, this phase summarizes the complete dataset.

Perform Map Reduce For Integer Number

Problem statement:

You are given a large number of files containing positive integers. Design the MapReduce process to compute the number of even integers across all files.

Before answering the question we will creating MapReduce job using positive integers with, <key, value>

Using MapReduce, determine how many odd and even numbers of jobs in positive integer jobs.

Lets Understand It Workflow 

What Mapper Do?

Maps input key/value pairs to a set of intermediate key/value pairs.

Maps are the individual tasks which transform input records into a intermediate records. The transformed intermediate records need not be of the same type as the input records. A given input pair may map to zero or many output pairs.

What are the key/value pairs that are INPUT to the first Mapper?

We can easily say that input for mapper is the combination of key/value, where key is offset and value is particular job.

{#offset, “2 4 5”}

This is the input for mapper which has argument where key = #offset and value = “2 4 5”

What are the key/value pairs that are OUTPUT of the first Mapper?

The output of Mapper the pairs of key/value, which is generated after filtering it with given condition, in above figure we will filter pairs of job which has even numbers:

Example: (2,“2 4 5”) and (1,“9 7 6”)

Applications of Map Reduce

MapReduce is used in many applications let us have a look at some of the applications:


Hadoop and MapReduce are used by Netflix to recommend the user some popular movies based on what they watched and which movie they like.

MapReduce can determine how users are watching movies, analyzing their logs and clicks.


Many E-commerce companies such as Flipkart, Amazon, and eBay use MapReduce to analyze the buying behavior of the customers based on customers’ interests or their buying behavior

MapReduce programming offers several benefits

Scalability. Businesses can process petabytes of data stored in the Hadoop Distributed File System (HDFS).

Flexibility. Hadoop enables easier access to multiple sources of data and multiple types of data.

Speed. With parallel processing and minimal data movement, Hadoop offers fast processing of massive amounts of data.

Simple. Developers can write code in a choice of languages, including Java, C++ and Python.

Programming Languages Used For Data Scientist & Machine Learning

There are many other programming languages and Tools which used to do Data Science and Machine Learning Task. Here we can discussing these programming languages in which our expert also providing the Data Science and Machine Learning programming Help:

Python: Python is the import programming language which start career as a Data Science and Machine Learning. This is first choice of professionals which learn data science. Now a day it became most popular programming language in the field of data science.

Java:  Java is also used for machine learning projects but it is difficult to implement compare to Python programming language. Syntax of this programming language is complex compare to python so developer not choose this as a first choice.

R: R programming is also became most familiar with Data Science and Machine Learning expert. This is also choose by Data Science expert like a python. It is also simple like python and it provide lots of in-built libraries which make it easy to implement.

JavaScript: When we need to create advance level GUI Application related to Machine Learning and Data Science for model prediction then JavaScript used to create the front end design.

MATLAB: MATLAB is also used to predict the Data Science and Machine Learning models. Basically it used to advance level scientific calculations which is related to machine learning.

SCALA: Scala is used in Data processing, distributed computing, and web development. It powers the data engineering infrastructure of many companies. It also used by Data Scientist Developer.

PySpark: It used to handle the Big Data related task. When data is too long then right choice to implement PySpark. It also support the SQL so it make easy to execute the query.

Hive/HADOOP: It also used by Big Data expert to implement big data related task. Now a day most of industries which is working over past decades then data of these industries is too long. To handle these data Hive/HADOOP is the right choice of developer. 

Tkinter: This is the python tool which used to create GUI applications. It also used to create Data Science and Machine Learning Application.

Django/Flask: These are the python Framework which is used to create GUI Applications. If you are looking to hire expert which can do your machine learning web application then you can choose these frameworks.

Sample Code


This problem is similar to the problem we worked on in lecture with a small twist (see below). Instead of printing out how many times a word appears in the file, you want to print out how many words have the exact same type of vowels. For this problem, only the number of vowels matters and the case does not matter (i.e cat is the same as CAt). A vowel is any letter from this set {a,e,i,o,u,y}. A word is any sequence of characters that does not contain whitespace. Whitespace is defined as: space, newline or tab. All of the following are 1 single word:


The output will be the vowel set, followed by a colon, followed by the number of words that contained exactly the vowel set. The output will have one answer per line (see example below).

‘hEllo’ and ‘pOle’ both contain exactly 1 e and exactly 1 o. The order of the vowels and the case from the original input word does not matter.
Imagine the following example:
hEllo    moose
pOle cccttt.ggg

We would end up with the following output:

The format should be as seen above: the vowels on each line are in alphabetical order, followed by a colon, then followed by the number of words that contained exactly those vowels. If there are words with no vowels, nothing is printed before the colon.



with open('input.txt','r') as file:
    # reading each line    
    for line in file:
        # reading each word        
        for word in line.split():
          word_new = word.lower()
          for w in word_new:
            if w in ['a','e','i','o','u','y']:
          # s.sort(key=str.lower)

with open('inp1.txt', 'w') as the_file:
    for r in res:
        if r=='':
            r+=' '
        the_file.write(r+' '+'1\n')

import sys
import re
with open("/content/inp1.txt",'r') as file:
    # reading each line    
    for line in file:
      line = line.strip()
      if l=='':
        l=' '
      if l in dd.keys():

for key in data_dict:
  print(key,' : ',data_dict[key])
