What is the Chatbot?

Encoder Decoder Architecture with Attention of Chatbots . The goal  of chat bot is to provide the conversation between a computer and a human there is a lot of research going on in this field of artificial intelligence to develop system that can perform this task however the generation based approaches that are currently being used in the development of those systems are promising this paper aims to provide a comprehensive overview of the various aspects of these systems including their capacities in terms of machine translation AL  chat bot is mostly deployed by financial organizations like bank credit card companies business like online retail stores and startups virtual agents are adopted by business ranging from very small startup to large corporation.

Introduction

A chat bot which is the  abbreviation for “chat plus robot” is a computer program that has conversations with human on any subject conversation al chat bot is a language recognition system that can carry on a question and answer dialogue with user with the user text or audio media can be used for communication nowadays we interact with our digital devices is largely restricted based on What features and accessibility  device offers however simple it may be there is a learning curve associated with each new device we interact with chat bot solve this problem by interacting with a user using text autonomously chat boards are currently the easiest way we have for software to be native to humans because they provide an experience of talking to another person one of the very first chat boards was rule based it was proposed in 1966 by  MIT professor Joseph Weizenbaum named as  ELIZA since chat bot mimic an actual person artificial intelligence techniques are used to build them.

Methodology

Auto encoder is a type of neutral network that aims to give output with minimum error from decoder when we input data to encoder a generalized architecture of encoder decoder is which allows input and output to be different with effectiveness the outlet of input and output can be vary and diverse we briefly describe encoder decoder with RNN with two successful imported decoder implementations among them the first encoder decoder was base RNN network with attention based on multilayer perceptron while second  describe the transformer encode decoder architecture that uses only a combination of feed forward neutral network with attention based on multiple heads.

What is RNN?

The RNN work on the principle of saving the output of a particular hidden layer and feeding this back to the input in order to predict the output of this layer. The X  Is the input node H is the hidden node with multiple layers and why is the output node when data is input from node X it is transferred to the hidden layer H which consist of multiple layers each with its own activation functions and weights and biases data is processed in hidden layer H and output is given from node Y the limitation of RNN is that it  works effectively only in small length of inputs data because it needs to compress data and give output for same length of data for large length of data it becomes difficult to compress large amount of data into fixed amount of vector yields poor performance.

RNN with Attention

It Consist of two RNN: encoder and a decoder encoder takes input process one word at a time its  objective  is to convert a sequence of word into a fixed size vector that includes only the important information discarding the unnecessary information you can visualize data information in the encoder along the time axis each hidden state influences the next hidden state in the final hidden state can be seen as a summary of sequence this state is called the context  from the context the decoder generates another sequence one symbol at a time here at each time step a decoder is influenced by the context any previously generated symbol.

Transformer

They introduce the original transformer architecture for machine translation performing better and faster than RNN encoder decoder models which were the mainstream the  encoder decoder architecture is used by the transformer the encoder extracts features from an input sentence which the decoder then used to generate an output sentence in transformer encoder in the transformer is made-up of several encoder blocks the encoder block process the input sentence and the output of the last encoded block becomes the input of the decoder. Decoder is also made-up of several decoder blocks decoded the input from encoder pass through each decoder and the last decoder block become the output.
