Bridging the Gap: Unifying the Training and Evaluation of Neural Network Binary Classifiers

NeurIPS 2022accept

While neural network binary classifiers are often evaluated on metrics such as Accuracy and $F_1$-Score, they are commonly trained with a cross-entropy objective. How can this training-evaluation gap be addressed? While specific techniques have been adopted to optimize certain confusion matrix based…

Gaze by Semi-Virtual Robotic Heads: Effects of Eye and Head Motion

We study human perception of gaze rendered by popular semi-virtual robotic heads, which use a screen to render a robot's face. It is known that when these heads are stationary, the screen may induce the Mona Lisa gaze effect, which widens the robot's apparent cone of direct gaze. But how do people p…
