Neuroscientists have long criticised deep learning algorithms as incompatible with current knowledge of neurobiology. We explore more biologically plausible versions of deep representation learning, focusing here mostly on unsupervised learning but developing a learning mechanism that could account for supervised, unsupervised and reinforcement learning. The starting point is that the basic learni
Parameter-specific adaptive learning rate methods are computationally efficient ways to reduce the ill-conditioning problems encountered when training large deep networks. Following recent work that strongly suggests that most of the critical points encountered when training such networks are saddle points, we find how considering the presence of negative eigenvalues of the Hessian could help us d
UITouchクラスのヘッダーを見てたらiOS8からmajorRadiusというプロパティが増えていた。 // majorRadius and majorRadiusTolerance are in points // The majorRadius will be accurate +/- the majorRadiusTolerance @property(nonatomic,readonly) CGFloat majorRadius NS_AVAILABLE_IOS(8_0); @property(nonatomic,readonly) CGFloat majorRadiusTolerance NS_AVAILABLE_IOS(8_0); 雑に説明すると、タッチしたときの指の半径を返してくれる。 実際にiPad mini Ratina 2013で試した感じでは下記のような測定値になる
