A novel sequence-to-sequence model predicts missing sensor data.
Not all types of supervision signals are created equal: Different types of feedback have different costs and effects on learning. We show how self-regulation strategies that decide when to ask for which kind of feedback from a teacher (or from oneself) can be cast as a learning-to-learn problem leading to improved cost…

The Softmax function is used in the final layer of nearly all existing sequence-to-sequence models for language generation.
