ChatGPT is a natural language processing (NLP) technology that enables bots to generate human-like conversations with users.
It uses a type of machine learning called “natural language generation” (NLG) to generate text and audio outputs.
ChatGPT takes in user input, runs it through a series of layers, and produces an appropriate response.
To understand how ChatGPT works, we’ll need to take a look at the components that make it up.
At the core of ChatGPT is a type of artificial intelligence called a recurrent neural network (RNN).
A RNN is a type of deep learning network that uses a number of “neurons” (i.e. computational nodes) to map out relationships between inputs and outputs.
If a user input is fed into the RNN, the model will learn to predict the corresponding output.
Once the user input is fed into the RNN, it is then processed through a series of layers.
The first layer is the contextual layer. Here, the input is parsed and “understood” by the system.
This layer is where the model learns to generate contextually relevant responses.
After the contextual layer, the input enters what's called the encoder layer. This layer “encodes” the user input into a vector form.
Here, the encoder layer is responsible for extracting the most important features from the input text.
The output of the encoder layer is then passed on to the decoder layer. This layer takes the encoded information and generates the output.
The decoder layer contains two components: a language model and an attention mechanism.
The language model is responsible for generating the text responses, while the attention mechanism allows the model to “pay attention” to certain parts of the input in order to generate more accurate responses.
Finally, the output of the decoder layer is fed into a post-processing layer. This layer cleans up the output and arranges it into a readable format.
By combining these layers, ChatGPT is able to generate conversations that are both natural and contextually relevant to a user. With no prior knowledge about a given topic, ChatGPT can answer questions and generate relevant conversations.
