In the method, a valve group voltage at a detection pole is obtained, voltages at voltage measurement points at the detection pole are collected, and comparison and determination are performed based on the actual arrangement of the voltage measurement points, and then whether an abnormal measurement occurs at each of the voltage measurement points is determined.

Abstract: Methods and systems for budgeted and simplified training of deep neural networks (DNNs) are disclosed. In one example, a trainer is to train a DNN using a plurality of training sub-images derived from a down-sampled training image. A tester is to test the trained DNN using a plurality of testing sub-images derived from a down-sampled testing image. In another example, in a recurrent deep Q-network (RDQN) having a local attention mechanism located between a convolutional neural network (CNN) and a long-short time memory (LSTM), a plurality of feature maps are generated by the CNN from an input image. Hard-attention is applied by the local attention mechanism to the generated plurality of feature maps by selecting a subset of the generated feature maps. Soft attention is applied by the local attention mechanism to the selected subset of generated feature maps by providing weights to the selected subset of generated feature maps in obtaining weighted feature maps.

Abstract: A hammock includes a hammock body and a hammock support, where the hammock body includes a fabric and a hammock body frame; the fabric is made of a flexible material and is fixedly connected to the hammock body frame; the hammock body is connected to the hammock support through hanging assemblies; and the hammock body frame is longitudinally foldaway from an unfolded state to a half-folded state and transversely foldaway from the half-folded state to a fully folded state. The hammock body is foldaway, and the fabric is large, comfortable and portable. When the hammock body is unfolded, the hammock is stable and will not collapse. When the hammock body is fully folded, the structure is compact and not easy to loosen.
