Person Re-identification (ReID), under the same or different cameras, judges whether two or more pictures are the same person through feature extraction and match of images of pedestrian detection box. In the past period of time, a lot of progress has been made in the field of pedestrian reidentification, and the recognition rate has reached a very high level. One important reason is that people re-examined the loss function, proposed various variants, and the effect has been greatly improved. In this paper, two different loss functions are used for comparison, and the influence of different loss functions on pedestrian re-recognition results is analyzed through the comparison results.

It is time-consuming and error-prone to manually determine whether there is a brain tumor in an image. However, traditional automatic classification algorithms have certain limitations, which makes the automation of brain tumor classification still a challenging problem. In this article, a new method for automatic classification of brain tumors is proposed, which combines neural network models with transfer learning methods, so as to improve or solve the problem of slow iteration and long time-consuming model generation, improve accuracy, and reduce parameter. In short, the convolutional neural network model (CNN) is combined with the method of transfer learning to achieve automatic image classification on the Brain Tumor Detection 2020 dataset provided by Model Whale. More specifically, during the experiment, Tensorflow was selected as the deep learning framework. First, the transfer learning method was used, and imagenet weights were used. Then, Comparing model performance by changing the choice of the backbone network of the CNN. Select the accuracy rate as the evaluation index, compare the performance of the model, use binary_crossentropy as the loss function, and the optimizer uses adam. In this paper, three backbone networks, VGG, MobileNet and ResNet, are compared. Experimental results indicate that the automatic classification of brain tumors with the combination of CNN model and transfer learning method has better performance and the VGG model has the best performance.

Investment strategies and development paths in key areas of power grid in the future are the focus of power enterprises. Considering the derivative value of power grid investment, this paper proposes a smart grid investment decision evaluation model based on binomial coefficient and variation coefficient. First, the concept, criteria and methods of grid investment derivative value are summarized; Secondly, the smart grid investment derivative value index system is constructed from three aspects: grid investment benefit, grid operation and maintenance effect, and sustainable development value; Based on binomial coefficient method and variation coefficient method,a combination weighting method of subjective and objective fusion is constructed, and dynamic combination factors are adjusted according to different scene requirements to achieve dynamic balance of multiple objectives, reflecting the complementary advantages of subjective and objective methods. At last.we use Curve Comparison Chart and Specific 3D Curve to prove the effectiveness and accuracy of our method.

The existing generalization-based location privacy protection scheme of Crowd-Sensing cannot balance user privacy needs and data quality, and uses a uniform policy to protect all locations of all users. To address this problem, this paper proposes a personalized privacy protection scheme, which first calculates the sensitivity of each location based on location entropy, access frequency and other features, and then encodes the location using Geo-hash code. The prefixes of different lengths are chosen according to the different sensitivities to achieve different strengths of privacy protection. Finally, a reasonable gridding algorithm is designed so that the data quality does not degrade as the protection strength increases, thus achieving the goal of improving data quality while protecting the user's location privacy. Finally, the effectiveness of the proposed algorithm is further verified through experiments.
