8th International Conference on Social Robotics
This paper assesses how the accuracy in user's answers influence the learning of a social robot when it is trained to recognize poses using Active Learning. We study the performance of a robot trained to
recognize the same poses actively and passively and we show that, sometimes, the user might give simplistic answers producing a negative impact on the robot's learning. To reduce this effect, we provide a method based on lowering the trust in the user's responses. We conduct experiments with 24 users, indicating that our method maintains the benefits of AL even when the user answers are not accurate. With this method the robot incorporates domain knowledge from the users, mitigating the impact of low quality answers.
