Get Help In Big Data Map-Reduce

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

 

Mapping

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>

 

Shuffling

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.

 

Reducing

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.

Get Help In Big Data Hadoop/HDFS

The Hadoop Distributed File System (HDFS) is the primary data storage system used by Hadoop applications. HDFS employs a NameNode and DataNode architecture to implement a distributed file system that provides high-performance access to data across highly scalable Hadoop clusters.

Here you can get good quality code from our expert. Our expert focus to deliver code without any Plagiarism and within your due. 

Big Data can be characterized by:
  • Volume - the amount and scale of data

  • Velocity - the speed at which data travels in and out

  • Variety - the range and complexity of data types, structures, and sources

Examples:

  • Financial markets - 7 billion shares change hands every day in the U.S. markets

  • Google, Twitter, GPS data, Facebook, YouTube, etc.

MapReduce is a framework for processing large-scale data using parallel and distributed computing technologies with a large number of computers. Apache Hadoop is an open-source implementation of MapReduce.

Big Data Analytics using Spark SQL

PySpark SQL is a module in Spark which integrates relational processing with Spark's functional programming API. We can extract the data by using an SQL query language. We can use the queries same as the SQL language. If you have basic understanding related to RDBMS, SQL, and Data Analytics then you can easily work with this. 

Feature of PySpark SQL: Consistence Data Access, Incorporation with Spark, Standard Connectivity, User-Defined Functions, Hive Compatibility

Ensemble Learning Assignment Help

A group of predictors is called an ensemble; thus, this technique is called Ensemble Learning, and an Ensemble Learning algorithm is called an Ensemble method. Ensemble methods, including bagging, boosting, and stacking. We will also explore Random Forests.

 

Bagging and PastingOne way to get a diverse set of classifiers is to use very different training algorithms, as just discussed. Another approach is to use the same training algorithm for every predictor and train them on different random subsets of the training set. When sampling is performed with replacement, this method is called bagging (short for boot-strap aggregating). When sampling is performed without replacement, it is called pasting.

  • Bagging and Pasting in Scikit-Learn: Scikit-Learn offers a simple API for both bagging and pasting with the BaggingClassifier class (or BaggingRegressor for regression). The following code trains an ensemble of 500 Decision Tree classifiers: each is trained on 100 training instances randomly sampled from the training set with replacement (this is an example of bagging, but if you want to use pasting instead, just set bootstrap=False). The n_jobs parameter tells Scikit-Learn the number of CPU cores to use for training and predictions (–1 tells Scikit-Learn to use all available cores):

Boosting: Boosting refers to any Ensemble method that can combine several weak learners into a strong learner. The general idea of most boosting methods is to train predictors sequentially, each trying to correct its predecessor. There are many boosting methods available, but by far the most popular are AdaBoost (short for Adaptive Boosting) and Gradient Boosting. Let’s start with AdaBoost.

  • AdaBoost: One way for a new predictor to correct its predecessor is to pay a bit more attention to the training instances that the predecessor underfit. This results in new predictors focusing more and more on the hard cases. This is the technique used by AdaBoost. For example, when training an AdaBoost classifier, the algorithm first trains a base classifier (such as a Decision Tree) and uses it to make predictions on the training set. The algorithm then increases the relative weight of misclassified training instances. Then it trains a second classifier, using the updated weights, and again makes predictions on the training set, updates the instance weights, and so on (see the following figure).

  • Gradient Boosting: Another very popular boosting algorithm is Gradient Boosting. Just like AdaBoost, Gradient Boosting works by sequentially adding predictors to an ensemble, each one correcting its predecessor. However, instead of tweaking the instance weights at every iteration like AdaBoost does, this method tries to fit the new predictor to the residual errors made by the previous predictor.

 

Stacking: The last Ensemble method we will discuss in this chapter is called stacking (short for stacked generalization). It is based on a simple idea: instead of using trivial functions (such as hard voting) to aggregate the predictions of all predictors in an ensemble, why don’t we train a model to perform this aggregation? The following figure shows such an ensemble performing a regression task on a new instance.

Docker, DataBricks, AWS and GCP Assignment Help

Many modern-day datasets are huge and truly exemplify “big data”. For example, the Facebook social graph is petabytes large (over 1M GB); every day, Twitter users generate over 12 terabytes of messages; and the NASA Terra and Aqua satellites each produce over 300 GB of MODIS satellite imagery per day. These raw data are far too large to even fit on the hard drive of an average computer, let alone to process and analyze. Luckily, there are a variety of modern technologies that allow us to process and analyze such large datasets in a reasonable amount of time.

A main goal of this assignment is to help students gain exposure to a variety of tools that will be useful in the future (e.g., future project, research, career). The reasoning behind intentionally including AWS, Azure and GCP (most courses use only one), because we want students to be able to try and compare these platforms as they evolve rapidly. This will help the students in the future. Should they need to select a cloud platform to use, they can make more informed decisions and be able to get started right away.

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.

Big Data PySpark Sample

Dataset: Use the Amazon Instant Video review file (reviews_Amazon_Instant_Video. json) and metadata (meta_Amazon_Instant_Video.json) from the Amazon product dataset (http://jmcauley.ucsd.edu/data/amazon/links.html). Download both files from the “Per-category files” section. 

Problem 2:

Big Data Query & Analysis using Spark SQL

This task is using Spark SQL for converting big sized raw data into useful information. Each member of a group should implement 2 complex SQL queries (refer to the marking scheme). Apply appropriate visualization tools to present your findings numerically and graphically. Interpret shortly your findings.

 

You can use https://spark.apache.org/docs/3.0.0/sql-ref.html for more information.

 

What do you need to put in the HTML report per student?

  • At least two Spark SQL queries.

  • A short explanation of the queries.

  • The working solution, i.e., plot or table.

 

Tip: The mark for this section depends on the level of your queries complexity, for
instance using the simple select query is not supposed for a full mark.

Problem 3:

Advanced Analytics using PySpark

3.1. Analyze and Interpret Big Data using PySpark

Every member of a group should analyze data through 3 analytical methods (e.g., advanced descriptive statistics, correlation, hypothesis testing, density estimation, etc.). You need to present your work numerically and graphically. Apply tooltip text, legend, title, X-Y labels etc. accordingly.


Note: we need a working solution without system or logical error for the good/full mark.

3.2. Design and Build a Machine Learning (ML) technique 
Every member of a group should go over https://spark.apache.org/docs/3.0.0/ml-guide.html and apply one ML technique. You can apply one the following approaches: Classification, Regression, Clustering, Dimensionality Reduction, Feature Extraction, Frequent Pattern or Optimization. Explain and evaluate your model and its results into the numerical
and/or graphical representations.

 

Note: If you are 4 students in a group, you should develop 4 different models. If you have a similar model, the mark would be zero.
