Top 5 ML Libraries and Tools That Every Java Developer Should Use
You may know that the face detection software, self-driving cars, and voice controlled devices all are built using Machine Learning (ML) frameworks. In upcoming years, a whole set of next-gen products through ML will transform the way we create, use products and the approaches that are being used to develop software and applications.
Java is the most famous programming language to build applications for mobile, web, desktop, and enterprise-grade solutions. It continually gets upgraded CLI, APIs, and module systems which make it one of the widely used platforms for machine learning.
However, how Machine Learning works using Java? Why should a Java developer get ahead with these ML tools and libraries? What are the current best tools to start with? Let’s find out.
Machine Learning with Java & why a Java developer should use the ML libraries and tools
Today, with Machine Learning, tech giants create core algorithms to power recommendations like Walmart products, detecting frauds at financial corporations, managing social media contents and even Google search results or maps. Evolved from the AI (Artificial Intelligence), Machine Learning performs the application quality improvements and extends their abilities without human involvement.
However, to execute such quality operations, ML requires a massive number of data (feature vectors) to identify the pattern and provide the output. Java language performs the best at delivering these sets of data. Java is the norm for handling Machine Learning algorithms as it is one of the most popular programming languages after Python. It helps to detect frauds, protect from cyber-attacks, and improve network security. Easy maintenance, marketability, readability, and community support are some of the main reasons for using ML tools with Java.
Have a look at the trending Libraries and Tools for Implementing Machine Learning in Java:
DeepLearning4j: DL4j or DeepLearning4j is one of the most favorite open-source libraries among the data scientists and Java Machine Learning developers. Its computing framework has full support for deep learning algorithms. DL4j is compatible with Scala, Kotlin, Clojure, and all the other JVM languages. It brings together deep neural networks & reinforcement learning to create and support various neural network structures. When it comes to recognizing the pattern, sentiment in the text, sound, or speech, then DL4j is extremely useful. It is meant for the business environment rather than research tools.
Java-ML (Java Machine Learning Library): Java-ML is an open source Java API/framework that provides dozens of ML algorithms. Instead of the graphical user interface, it has a clear interface aimed at the Java programmers, software professionals, and scientists. You need to have sound knowledge in Java programming to leverage its functionalities. The wide range of Java-ML algorithms includes feature selection, data preprocessing, ranking, classification, clustering, and more. A clear interface for the same kind of algorithms allows quick implementations. Java-ML supports every file type. It has a plethora of source code samples and tutorials available.
Weka: Weka (Waikato Environment for Knowledge Analysis) is the most popular Java ML platform which is free and naturally portable. You can directly apply Weka ML algorithms to datasets or can call from the Java code. Weka has a user-friendly GUI that helps for a smooth integration through Java APIs. Its more than 267 algorithms perform general purpose and complex ML tasks like data analysis, visualization, attribute selection, anomaly detection, mining of association rules, and more. The Weka 3 workbench is widely used by the data scientists and is perfect for developing new Machine Learning schemes.
Apache Spark: Spark is a platform that helps to implement and use ML algorithms through Apache ML library. It efficiently carries machine learning to calculate clusters and combines with TensorFlow for deep learning. Spark MLib is written in Scala, and it uses Breeze- a linear algebra package. You can use MLib in Java, Scala, R, and Python and can plug it into Hadoop workflows easily. The standard algorithms supported by Spark include optimization, feature extraction, dimensionality reduction, and collaborative filtering (not deep neural network). Apache Spark is 100x faster than MapReduce due to its high iterative computation.
MALLET: MALLET (Machine Learning for Language Toolkit) is also an open-source library. It drives growth for ML applications through its vast NLP algorithms and utilities. MALLET provides assistance in document classification, extraction of information, topic modeling, sequence tagging, and numerical optimization. The Java command line interface and APIs help to run the programs successfully. GRMM which is an add-on package of MALLET supports the graphical model inference and CRFs training along with an arbitrary graphical structure. Though, the exciting aspect of this is you can use it for both the open-source and commercial app development.
There are other famous Java Machine Learning libraries & tools like Shogun, MOA, RapidMiner, JSAT, and ELKI offer Java developers with a wide range of possibilities. Some of them are ML development platforms while others are containing a vast collection of ML algorithms. Any company providing Java web development today looks for the developers who also have acquired knowledge of Java ML libraries and tools. When you are going to design, build, and deploy any Machine Learning application, these tools and libraries will be supportive.
Round Robin is a strategy for scheduling territorial sales, which sounds not only as to music to most ears, but it is also a very interesting topic for understanding for users of easy to use CRM software.
Whether you are planning to arrange a seminar or conference, university alumni meeting, or recruitment for the company, you will need to cope with many things to keep everything streamlined. Moreover, you may have to deal with some last minute glitches which need teamwork and much workforce for making the event engaging and memorable
Many times, people are having queries related to secured PDF files having the owner password. Basically, these files are restricting them to edit and print PDF documents. Therefore, in such cases, it becomes necessary for the user to remove permission password from PDF documents.
When an injury or fatality happens at a workplace, it causes immeasurable suffering and problems to the employees & their families. Moreover, it costs the organizations large & inexorable expenses every year. To minimize these unwanted pains, companies are switching to the OHS (Organizational Health and Safety) management systems
Automated testing is one of the most efficient ways to create a high-quality application within the resources and tools available. Automated testing can help you save valuable time and in creating an automate error-proof testing procedure. But it isn’t that simple to automate your testing process and get results fast.
The world of eCommerce has become extremely competitive at this time. This is the era where eCommerce companies are at their peak. And, at the same time, the competition in the eCommerce industry is also increasing like anything.
Almost everybody who is involved in the software development process has seen this situation whereas, the team just released a new edition of the application, however, there is something that’s not right, and something needs improvement. You and your team might have spotted something while testing that still needs some work. But right now, you are feeling the heat, as you have to act quickly in order to fix the issue.
Testing one's restrictions is something most of us experience every day, and in the world of web and mobile applications it's important a little pressure is requested a company to learn how these function.
'Regression' a word that is considered with a lot of pain by software testers around the technical world. Sometimes, we even wonder whether regression testing is needed? Why do we need to execute it when a bug-free software can never be ready?
