Before revision:  Although previous research has proposed successful task-model encoders that analyze images and human body movements, the encoders have been designed in environments without noise. Therefore, there has been little discussion on how to guide a task-model encoder in a scene with spatio-temporal noises  such as cluttered objects or unrelated human body movements.
