Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003 Abstract This paper reviews a recent set of behavioural studies that examine the scope and nature of the representational system underlying theory-of-mind development. Studies with typically developing infants, adults and children with autism all converge on the claim that there is a specialized input system that uses not only ...

You Only Look Once: Unified, Real-Time Object Detection [PDF]
Computer Vision and Pattern Recognition, 2015 We present YOLO, a new approach to object detection. Prior work on object detection repurposes classifiers to perform detection. Instead, we frame object detection as a regression problem to spatially separated bounding boxes and associated class ...

Faster R-CNN: Towards Real-Time Object Detection with Region Proposal Networks [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2015 State-of-the-art object detection networks depend on region proposal algorithms to hypothesize object locations. Advances like SPPnet and Fast R-CNN have reduced the running time of these detection networks, exposing region proposal computation as a ...
