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 multifunctional platform includes a platform frame including a base having an annular center hole and two parallel arms, a hoist mechanism including traction devices and moves the platform up and down, tower clamping mechanisms around the circumference of the annular center hole and preventing the platform frame from rotating, a moving dolly sliding on the two arms, two blade adjusting pedestals respectively provided on the protruding ends of the two arms, two set of blade drawing mechanisms, one end of each set of blade drawing mechanism is respectively connected with one blade adjusting pedestal. The blade disassembling method includes lifting the multifunctional platform to an appropriate height of the tower by the hoist mechanism, tying sling ropes at three positions of a blade, disassembling the blade and lowering it to a transport ship by a crane ship, and a fan maintenance crane, and the blade drawing mechanisms.
