Top 10 Machine Learning Frameworks {Complete Guide}

There has been exponential growth in the field of Machine Learning/Artificial Intelligence and it has created a boom in the technology field. According to the reports, it has created millions of jobs and has led to the evolution of many Machine Learning frameworks. Today we will look into some of these most popularly used Machine Learning Frameworks. What is Machine Learning? Machine Learning is a part of Artificial Intelligence, consisting of algorithms that work on outputs generated from previous experiences. The more input parameters (more experiences) they get, the better the results can be expected. The uniqueness of these algorithms is that they don’t require human intervention. But, the human brain is always required to understand which machine learning algorithm will fit best for a particular situation. Data sets (inputs) are divided into training and testing sets. Machine learning algorithms work on the training data sets in order to build models for prediction and decision making. Some applications of machine learning are computer vision, collaborative filtering, natural language processing, spam filtering, etc. What is a Machine Learning Framework? ML models can be easily developed with the help of Machine Learning frameworks, without knowing the ML Algorithm. Python is the most widely used language in machine learning and so most of the ML frameworks are built for programming in Python language.  Machine Learning with R Programming is also widely used in Data Science fields.  Read More:- IS PYTHON ENOUGH FOR MACHINE LEARNING 10 Machine Learning Frameworks widely used are:- Tensorflow Keras Scikit-learn Theano Amazon SageMaker Spark ML Microsoft Cognitive Toolkit (CNTK) H20 Caffe Torch Tensorflow Google’s Tensorflow is the most popularly used framework for machine learning/deep learning.

5 Best Big Data Tools You Must Know

Data – a four-lettered word that makes the world go round. As per research conducted by DOMO, “Over 2.5 quintillion bytes of data are created every single day, and it’s only going to grow from there. By 2020, it’s estimated that 1.7MB of data will be created every second for every person on earth.”   An increase in the number of users of the internet and influx of data has also made things simpler for businesses. An economic environment is made up of transactions between consumers and businesses. Similarly, a business organization is nothing without its human resource. Interaction between these resources is streamlined and made simpler with the help of data analysis. As rightly said by Atul Butte in Stanford, “Hiding within those mounds of data is knowledge that could change the life of a patient, or change the world.” If these sentences do not make any sense to you, let us tell you how data can help businesses – With the help of collected data of consumers, your business can redesign its marketing strategies to achieve better results. Through data, your business can hire better resources with the help of online tools. Data can help your business predict future trends and modify your plans as per them. Data can also help in personalizing the experience of your consumers, thereby, increasing their satisfaction. However, the question which arises now is that if there’s a sea of data being generated every minute, how does a business reach a decision with its help? This is where Big Data comes in. WHAT IS BIG DATA? In simple words, big data is data generated from various sources and through different formats. Thanks to the amount of information available on internet, the accumulated data is growing exponentially every day.  Big data is primarily defined through Vs. Let us tell you what they are – VELOCITY: Data flows in higher velocity and speed than in earlier times.  The number of internet users have helped in accelerating the pace. VARIETY: From pictures, videos to information and numbers, the type of data pouring in through various channels is varied as it can get VOLUME: The amount of data generated every minute is growing in leaps and bound. As per statistics, the average amount of data generated every minute is US alone is 2,657,700 gigabytes. As data has been multiplied hundreds of times, its analysis has become even more difficult. Data comes in all kinds of forms – structured and unstructured.  To make this data useful by drawing information and insights, we need systems which are much more advanced than traditional databases. This is where Big Data tools and analytics come in. “Without big data analytics, companies are blind and deaf, wandering out onto the web like deer on a freeway.” – (Geoffrey Moore, author and consultant) In this article, we will walk you through some of the best big data tools to look out for in 2019 TOP BIG DATA TOOL YOU MUST KNOW HADOOP: If there’s a discussion about big data, it is incomplete without a mention of Hadoop. Literally, Hadoop and big data are inseparable. Even in 2019, Hadoop remains significant and relevant in the world of Big Data analytics. SO, WHAT IS HADOOP? Hadoop is an open-source framework that helps in storing data and tackling big data in an efficient way. It first came into existence in early 2000s; around the same time as Google.  It began as a search engine indexing tool and grew more technical with features like storing and processing data. Over time, hadoop has become synonymous with big data analytics and still remains important. It is low cost and has easy accessibility. It has four components – Hadoop Common:  basic utilities for every kind of case. Hadoop Distributed File System (HDFS): a database for storing data in a simple manner Hadoop MapReduce:  Helps in processing and simplifying a large set of data by filtering and analysis. Hadoop YARN: helps in resource management and scheduling. Even though, it is as old as the term “Big Data”, it still remains the backbone of it. Thanks to its affordability, open libraries and scalability, Hadoop still has a growing scope in 2019. Learning Hadoop will give you a solid base and understanding of Big Data. It will also help you in learning other technologies like Apache Spark etc. APACHE SPARK: Developed in 2009 at UC Berkeley, Apache Spark is one of the most popular open-source data processing engines with APIs in varied forms like Java, Python, SQL and R. Apache Spark was developed to provide speed, ease of use and sophisticated analysis. In an article in Forbes, Apache Spark was called Taylor Swift of Big data as it has been around for a while but grabbed eyeballs only around 2015. In the past few years, Apache Spark has gained a lot of admirers mainly because of the following reasons – It uses electronic memory rather than completely relying on hard disk which makes it 10 times faster. Even though it doesn’t have its own database, it can easily be integrated with any system like HDFS, MongoDB and Amazon’s S3 system. It is the most preferred framework for Machine Learning. Machine Learning is the present and the future of technology. With the help of Spark Streaming, data can be analyzed in real-time. Start Learning Apache Spark Apache Spark was developed as an improvisation of Hadoop and is still flourishing. It is now considered as one of the key and mature tools for Big Data Analytics. Even with introductions of new technology, Apache Spark continuous to rule the Big Data ecosystem. APACHE CASSANDRA: The software world runs on scalability. And, Apache Cassandra is a highly scalable, no SQL, open-source framework. Open-sourced in 2008 by Facebook, Apache Cassandra provides certain advantages that no other relational database or SQL can give.  Some of these advantages are – – DECENTRALIZATION: Apache Cassandra doesn’t have a master-slave architecture. Every cluster is identical eliminating a single point of failure or network bottlenecks. – HIGHLY ELASTIC: Its unique decentralized architecture makes adding new nodes easy, thus, enables it to handle a large amount of data across channels. – LINEAR SCALABILITY: Scaling is easier and simpler as no single node is interdependent on each other, and adding a new node can help you scale as much as you would like. Apache Cassandra has been helping big shots like Apple, Spotify, Instagram, ebay etc. Its ability to handle multiple concurrent users without affecting the performance makes it the first choice of many organizations. In 2019, Apache Cassandra will only continue to grow as more and more people realize its benefits. MongoDB: Just like Apache Cassandra, Mongo DB is another NoSQL database. With its high flexibility, cost-effectiveness and open-source libraries, Mongo DB is the fastest growing technology. It is simple, dynamic and object-oriented. What makes it different from the traditional databases is its document store model in which data is stored as a document rather than in columns of a traditional database. Some of the advantages it offers are – Because of its rich document-based data system in the form of BSON etc, a large variety of data like integer, string, array can easily be stored. – Its infrastructure is cloud-based making it highly flexible. – It uses dynamic schemas which allows data to be set up quickly. This helps in saving cost and time – It helps in the real-time analysis of data. Mongo DB is highly preferred for e-commerce websites, social networking sites and content management.  All of these are the need of the hour in 2019. As the most important part of MEAN Stack, it is the most preferred framework by startups. Moreover, bigger companies too are adopting it quickly. APACHE SAMOA : Coming back to the Apache family, Apache SAMOA is one of the most popular big data tools especially for the graphical databases.   SAMOA stands for Scalable Advanced Massive Online Analysis and really, the abbreviation explains it all. Apache SAMOA is an open-source platform which has a collection of the distributed streaming algorithm for data mining and machine learning tasks such as – -Regression, -Clustering -Classification -Program Abstraction It has a pluggable architecture which allows it to run on many distributed stream processing engines like – – Apache Storm – Apache S4 – Apache Flink Apache Samoa is the most preferred framework for Machine learning as it facilitates the development of new machine learning algorithms without interfering with the complexity of underlying distributed stream processing. Some major reasons why it is preferred are – With its pluggable and reusable architecture, deployment becomes easy. – There’s no downtime. – Once a program is completed, it can be run everywhere. – Simple process. CONCLUSION: Big Data is the biggest trend of 2019 and of the coming future. An understanding and proficiency in big data help in carving a bankable career path for yourself. Our suggestion would be to begin your journey in Big Data with Hadoop and Spark. These two technologies are a pioneer in the world of Big Data and will always remain the basis of analytics.

Big Data Hadoop Tutorial for Beginners

Introduction to Big Data Big data refer to all the data generated through various platforms across the world. A data is classified as big if the total size is more than 1 GB/TB/PB/EX. Categories of BigData: 1) Structured 2) Unstructured 3) Semi-structured Example of BigData: 1) New York Exchange generates about 1 TB of new trade data per day. 2) Social Media:  Statistics show that 500+ terabytes of data get ingested into the database of social media site Facebook, every day. Data mainly generated in terms of Photos & video uploads Message exchanges Putting comments etc. 3) Jet Engine /Travel Portals: Single Jet Engine generates 10+ terabytes(TB) of data in 30 minutes of a flights per day.  Generation of data reaches up to many Petabytes (PB). What is Hadoop? Hadoop is an open-source framework managed by The Apache Software Foundation. Open source implies that it is freely available and its source code can be changed as per the requirement. Apache Hadoop is designed to store & process big data efficiently. Hadoop is used for data storing, processing, analyzing, accessing, governance, operations & security. Large organization with a huge amount of data uses Hadoop software, processed with the help of a large cluster of commodity hardware. Cluster term refers to a group of systems that are connected via LAN and multiple nodes on this cluster helps in performing the jobs. Hadoop has gained popularity worldwide in managing big data and at present, it has covered nearly 90% market of big data. Suggested Read:- DIFFERENCE BETWEEN DATA SCIENCE, DATA ANALYTICS AND MACHINE LEARNING Features of Hadoop: Cost-Effective: Hadoop system is very cost-effective as it does not require any specialized hardware and thus requires low investment. The use of simple hardware known as commodity hardware is sufficient for the system. Supports Large Cluster of Nodes: A Hadoop structure can be made of thousands of nodes making a large cluster. Large cluster helps in expanding the storage system & offers more computing power. Parallel Processing of Data: Hadoop system supports parallel processing of the data across all nodes in the cluster, and thus it reduces the storage & processing time. Distribution of Data(Distributed Processing): Hadoop efficiently distributes the data across all the nodes in a cluster. Moreover, it replicates the data over the entire cluster in order to retrieve the data from other nodes, if a particular node is busy or fails to operate. Automatic Failover Management (Fault Tolerance): An important feature of Hadoop is that it automatically resolves the problem in case a node in the cluster fails. The framework itself replaces the failed system with another system along with configuring the replicated settings & data on the new machine. Support Heterogeneous Cluster: the Heterogeneous cluster is one that accounts for nodes or machines which are from a different vendor, different operating system and running at different versions. For instance, if a Hadoop cluster has three systems, one IBM machine that runs on RHEL Linux, the second is INTEL machine running on Ubuntu Linux and third is AMD machine running on FEDORA Linux. All of these different systems are capable to run simultaneously on a single cluster. Scalability: A Hadoop system has the ability to add or remove node/nodes and hardware components from a cluster, without affecting the operations of the cluster. This refers to scalability, which is one of the important features of the Hadoop system. Must Read:- WHY BIG DATA WITH PYTHON IS TOP TECH JOB SKILL  Overview of Hadoop Ecosystem: The Hadoop ecosystem consists of 1) HDFS (Hadoop Distributed File System) 2) Apache MapReduce 3) Apache PIG 4) Apache HBase 5) Apache Hive 6) Apache Sqoop 7) Apache Flume, and 8) Apache Zookeeper 9) Apache Kafka 10) Apache OOZIE These components of the Hadoop ecosystem are explained as follows: HDFS (Hadoop Distributed File System): HDFS has the most important job to perform in the Hadoop framework. It distributes the data and stores them on each node present in a cluster simultaneously. This process reduces the total time to store data onto the disk. MapReduce (Read/Write Large Datasets into/from Hadoop using MR) : Hadoop MapReduce another most important part of the system that processes the huge volume of data stored in a cluster. It allows parallel processing of all the data stored by HDFS. Moreover, it resolves the issue of the high cost of processing through the massive scalability in a cluster. Apache PIG (PIG is a kind of ETL for Hadoop Ecosystem): It is the high-level scripting language to write the data analysis programs for huge data sets in the Hadoop cluster. Pig enables the developers to generate query execution routines for the analysis of large data sets. The scripting language is known is Pig Latin which one key part of Pig & the second key part is a Apache HBase (OLTP/NoSQL) sources: It is a column-oriented database that supports the working of HDFS on real-time basis. It is enabled to process large database tables i.e. a file containing millions of rows & columns. An important use of HBase is the efficient use of master nodes for managing region servers. Apache Hive (HIVE is SQL Engine on Hadoop): It is a language similar to SQL, which allows the squaring of data from HDFS. The Hive version of SQL language is called as HiveQL. Apache Sqoop(Data Import/Export from RDBMS(SQL sources) into Hadoop): It is an application that helps in import & export of data from Hadoop to other relational database management systems. It can transfer the bulk of data. Sqoop is based on connector architecture that backs the plugins for establishing connectivity to new external systems. Apache Flume(Data Import from Unstructured(Social Media sites)/Structured into  Hadoop)  : It is an application it allows the storage of streaming data into the Hadoop cluster, such as data being written to log files is a good example of streaming data. Apache Zookeeper ( Co-ordination tool used in a Clustered environment (Hadoop)): Its role is to manage the coordination between the above-mentioned applications for their efficient functioning in the Hadoop ecosystem. Functioning of Hadoop – HDFS Daemons Hadoop system works on the principle of master-slave architecture. HDFS daemons consist of the following: Name Node: It is the master node, and is single in the It is responsible for storing HDFS Metadata that keeps track of all the files that are stored in the HDFS.  The information stored on Metadata is like the file name, file permission it has, authorized user of the file & the location where it is stored. This information is stored on RAM which is generally called as file system Metadata. Data Nodes: It is the slave node, and is present in multiple numbers. Data nodes are responsible for storing & retrieving the data as instructed by the name node. Data nodes intermittently report to the name node with their present status & all the files stored with them. The data nodes keep multiple copies of each file stored in them. Secondary Name Node: Secondary name node is present to support the primary name node in storing the Metadata. On the failure of name node due to corrupt Metadata or any other reason secondary name nodes prevent the dysfunctioning of the complete cluster. The secondary name node instructs the name node to create & send fsimage & editlog file, upon which the compacted fsimage file is created by the secondary name node. This compacted file is then transferred back to name node and it is renamed. This process repeats after every 1 hour or when the size of editlog file exceeds 64MB. The functioning Hadoop system can be better understood with the help of a live example. Let us take the example of a banking system. Banks are required to analyze loads of unstructured information with them which is collected through various sources such as social media profiles, calls, complaint logs, emails, discussion forums, and also through traditional sources of collecting information like cash and equity, transactional data, trade, and lending, etc. for better understanding & analyzing the customers. The financial firms are now adopting the Hadoop system in order to structurally store the data, access the data, and analyzing & extracting the key information from the data that will provide comprehensive insights to help to make the right & informed decision.
