Sparrow
DeepMind
Sparrow is a research model and proof of concept, designed with the goal of training dialogue agents to be more helpful, correct, and harmless. By learning these qualities in a general dialogue setting, Sparrow advances our understanding of how we can train agents to be safer and more useful – and ultimately, to help build safer and more useful artificial general intelligence (AGI). Sparrow is not yet available for public use. Training a conversational AI is an especially challenging problem because it’s difficult to pinpoint what makes a dialogue successful. To address this problem, we turn to a form of reinforcement learning (RL) based on people's feedback, using the study participants’ preference feedback to train a model of how useful an answer is. To get this data, we show our participants multiple model answers to the same question and ask them which answer they like the most. -

The SecondEGO digital assistant is the only chatbot that has the most advanced comprehensive support for the Slovenian language built-in. Even for flexibility! Teach the SecondEGO chatbot yourself with the help of simple mind diagrams. Hiring expensive programmers is not necessary. Gain visual clarity with mind diagrams. Without visual transparency, you lose control of learning from other digital assistants right from the start.
