To solve the problems of large number of similar Chinese characters,
difficult feature extraction and inaccurate recognition, we propose a novel
multilevel stacked SqueezeNet model for handwritten Chinese character
recognition. First, we design a deep convolutional neural network model for
feature grouping extraction and fusion. The multilevel stacked feature group
extraction module is used to extract the deep abstract feature information
of the image and carry out the fusion between the different feature
information modules. Secondly, we use the designed down-sampling and channel
amplification modules to reduce the feature dimension while preserving the
important information of the image. The feature information is refined and
condensed to solve the overlapping and redundant problem of feature
information. Thirdly, inter-layer feature fusion algorithm and Softmax
classification function constrained by L2 norm are used. We further compress
the parameter clipping to avoid the loss of too much accuracy due to the
clipping of important parameters. The dynamic network surgery algorithm is
used to ensure that the important parameters of the error deletion are
reassembled. Experimental results on public data show that the designed
recognition model in this paper can effectively improve the recognition rate
of handwritten Chinese characters.
Unmanned aerial vehicles (UAV) are becoming more and more popular. In all sectors of society can see the presence of unmanned aerial vehicles. However, the short flight time and flight distance always restrict the development of UAV. The most imminent and creative work is how to make the perfect combination of new energy technologies with UAVs. In this paper, a wind-solar hybrid power generation system and its operation scheme design are discussed, and the application of the wind solar hybrid power generation system controlled by a single-chip microcomputer is discussed. The experimental results show that this kind of power generation system and its operation scheme are improved compared with the conventional design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
