Neuropsychology: Reflections on mirror images
A recent advertising campaign ran a picture of eight copies of the Mona Lisa. In four of them she faced left, as in Figure 1, and in the other four she faced to her right. All but two of them had a detail changed: for example, which hand crossed on top. The slogan with the advert ran “Don’t mistake familiarity for knowledge”. Anyone looking at the advert would be sure the picture was the Mona L...
متن کاملMirror images: Matter and Antimatter
Existing theories of physics struggle to explain the difference between matter and antimatter in ways that make physical sense. This paper offers a reconceptualisation based on the cordus conjecture. We create a new concept of handedness, called ma, and an operational definition based on the energisation sequence of the cordus reactive-ends. Each reactive end for a stable matter particuloid, e....
متن کاملMirror images and unilateral spatial neglect.
Responding correctly to a mirror image requires the creation of a rather peculiar form of dual representation. Mirror agnosia and mirror ataxia, i.e. a deficit in reaching an object reflected in a mirror, have been reported to be associated with parietal lobe lesions. This prospective study was conducted to investigate the capacity of subjects with neglect to identify the mirror image nature of...
متن کاملWhat do fish make of mirror images?
Fish act aggressively towards their mirror image suggesting that they consider it another individual, whereas in some mammals behavioural response to mirrors may be an evidence of self-recognition. Since fish cannot self-recognize, we asked whether they could distinguish between fighting a mirror image and fighting a real fish. We compared molecular, physiological and behavioural responses in e...
متن کاملAccelerating Reinforcement Learning by Mirror Images
あらまし 本研究では,強化学習の代表的な手法の Q学習を使用して,追跡問題のための学習速度の向上手法を提案 する.本研究のアイデアは,鏡像による対称性を利用して,フィールドの Q値を学習することにある.このことで左 右の対象差のみを伴う学習をすることが可能である.また,Q値の同時更新による収束性についても論じる. In this investigation we propose how to accelerate Q-learning which is one of the most successful reinforcement learning methods using mirror images for hunting problems. Mirror images have symmetric differences on right and left views, th...
