Phases of web development

The process of developing web application and websites which works using the internet is known as web development. Web developers need to use scripting languages at both the server and client end. A content management system is necessary to create a static website (one page) to a full-blown web application. Website development includes the coding of the application logic, designing the user interface, incorporation of database and managing the user queries, hosting the website on the server, and maintaining and updating the website.

Which of the following statements about various neural network layers is true? (Multiple Answers Possible) A. A perceptron, or fully-connected layer, lacks the ability to capture class imbalance information in training data. B. A multi-layer perceptron can consider the interactions between multiple input fea- tures and an output class. C. A convolutional layer is best applied when the input to that layer contains local structure. D. A pooling layer can only be applied to 2-dimensional or higher input data. E. A vanilla RNN cell can be formulated as a fully-connected layer operation, half of whose inputs at each timestep from previous output and half from an input sequence.
