What is Grails Programming & Frameworks Training ?

 Grails Programming & Frameworks Training

Grails is a dynamic framework, coined by the Groovy JVM programming language. It is an object-oriented language for the Java platform which intends to enhance developer productivity. The syntax is compatible with Java, and it’s compiled to JVM (Java Virtual Machine) bytecode. Grails works with Java technologies, including Java EE containers, Spring, SiteMesh, Quartz, and Hibernate.

Uses:

  • It is very developer-friendly as it comes with detailed and easy-to-read documentation
  • You can also build your own plugins and include the Grails IDE support for different platforms.
  • Most of the e-commerce sites make use of Grails

Advantages

  • It utilizes Groovy as its coding standard and since Groovy is similar to Java, programmers think it is easier to begin with Grails.
  • Easy to use the object mapping feature
  • It promotes reuse of code between different Grails application by modularizing the application in the form of plugins
  • Provides flexible profiles

What is PageRank (PR) ? | Comingfly

What is PageRank (PR) ? PageRank ( PR) is an algorithm used by Google Search to rank websites in their search engine results. PageRank was named after Larry Page, one of the founders of Google. PageRank is a way of measuring the importance of website pages. According to Google: It is not the only algorithm used by Google to order search engine results, but it is the first algorithm that was used by the company, and it is the best-known. Algorithm The PageRank algorithm outputs a probability distribution used to represent the likelihood that a person randomly clicking on links will arrive at any particular page. PageRank can be calculated for collections of documents of any size. It is assumed in several research papers that the distribution is evenly divided among all documents in the collection at the beginning of the computational process. The PageRank computations require several passes, called “iterations”, through the collection to adjust approximate PageRank values to more close...

WHAT ARE NEURAL NETWORKS? | Comingfly

WHAT ARE NEURAL NETWORKS ? Neural Networks the process of machine learning are neural networks. These are brain-inspired networks of interconnected layers of algorithms, called neurons, that feed data into each other, and which can be trained to carry out specific tasks by modifying the importance attributed to input data as it passes between the layers. During training of these neural networks, the weights attached to different inputs will continue to be varied until the output from the neural network is very close to what is desired, at which point the network will have 'learned' how to carry out a particular task. A subset of machine learning is deep learning, where neural networks are expanded into sprawling networks with a huge number of layers that are trained using massive amounts of data. It is these deep neural networks that have fueled the current leap forward in the ability of computers to carry out task like speech recognition and computer vision. T here are vario...
