Recently, Facebook AI Research (FAIR) has developed and introduced a role-playing fantasy game world to improve the efficiency of conversational AI models such as virtual assistants. The researchers proposed a full-fledged framework to boost open-domain dialog by using a gaming method that would provide a Lifelong Learning process.

Throughout their lives, human beings learn languages through the experiences they have with other people. However, a study in complex natural language processing (NLP) models is carried out utilizing a predetermined data set without the privilege of the model to communicate with humans using language at any point.

Studies in natural language processing are typically based on crowd-sourced structured datasets and the supervised learning method in model training. Such crowd-sourced databases are obtained by charging the crowd-workers to conduct contact and annotation activities.

However, research findings have shown that user-generated data is concerned with the lack of naturalness and importance to real-world use cases. That is because the study expenses for charging the crowd-workers mean that there is a limit cap on the processing of results.

Furthermore, as the crowd-workers are driven by compensation and not my involvement in the actual tasks themselves, the data distribution may not suit the intended one. Likewise, there are other problems, such as the static dataset framework, which does not require a model to benefit from its language-use experience.

Researchers have developed and released a role-playing game in which human players interact with learning agents situated in the open-domain fantasy universe. They researched the potential of an open-domain discussion model to learn iteratively from primarily human-driven interactions.

To boost participation, the researchers have selected a fantasy game world. The program varies between gathering data on human-model encounters, retraining and redeploying modified versions with recently acquired data. Simultaneously, it offers a simple criterion for testing and analyzing online models utilizing the Player Continuation model.

The game integrated into this work is a responsible for training and evaluating open-domain dialogue agents. The central game includes combining two agents in a defined environment where one is a human player and the other is a dialogue agent with the corresponding machine learning model. The two players are given roles with names and identities, such as People, and their current position and explanation. Every player has to play the role-play dialogues of their protagonists in a given scenario. Play dialogs are in the English language.

Increasing dialog or mini-game consists of 6 dialog turns per person. After the mini-game, the human player must select alternatives such as going to a different location or finishing the game. Several mini-games offer various role-playing options and thus make the dialogue data more dynamic.

According to the study, there are other advantages of the usage of the program, such as:

  • This framework is cost-effective than the conventional approaches of data collection and preparation of NLP models.
  • The data obtained were more successful in increasing the rate of continuity owing to more on-distribution than crowd-sourced results.
  • When the design develops, continuation rates are also increasing. As a result, the processing of data would increase.
  • This offers continuous dialogue learning, not by crowd-workers, but by human beings.

As a result, researchers have effectively obtained, retrained, and redeployed models that boost both the offline automated metrics and human continuous performance. They claimed that the program is capable of gathering data at a rate of 1/5th of the cost per crowdsourcing, where the expense of the process is the expense of ads that makes players aware of the game. Furthermore, this research is claimed to be more effective than crowdsourced data when used in interactions with actual users.
