Architecture for generating QA pairs from contexts

A context-based QA generating device, comprising:

• a latent variable generating network including at least one encoder and an artificial neural network (Multi-Layer Perceptron:
• MLP) and configured to train the artificial neural network using a first context, a first question, and a first answer, and generate a second question latent variable and a second answer latent variable by applying the trained artificial neural network to a second context;
• an answer generating network configured to generate a second answer by decoding the second answer latent variable;
• and
• a question generating network configured to generate a second question based on the second context and the second answer;
• wherein the second question and the second answer are characterized by a high mutual information to strengthen a consistency;
• and wherein the second answer latent variable is forced to be dependent on the second question latent variable.
