In recent years, the authors devoted themselves to the digraph variant of 1-2-3 Conjecture. Digraph D has a k-arc-coloring, which required that in-arc sum is different from out-arc sum for any arc, which be called adjacent vertex sum distinguishing coloring, also be known as (−, +) variant of 1-2-3 Conjecture. Julien Bensmail, Kasper Lyngsie proved that adjacent vertex sum distinguishing chromatic number is no more than three for every nice digraph. And they give a series of results about complexity. Deciding whether chromatic number less than or equal to three holds is NP-complete for nice digraph D, therefore it is meaningful to study the chromatic number equal to two or equal to three. This paper mainly studies (−, +) variant of 1-2- 3 Conjecture of digraph, and discuss some digraphs that adjacent vertex sum distinguishing chromatic number is equal to 2.","PeriodicalId":405065,"journal":{"name":"2022 International Symposium on Intelligent Robotics and Systems (ISoIRS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131036196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We establish a Bidirectional Long ShortTerm Memory Network based Proximal Policy Optimization (BiLSTM-PPO) algorithm. Then, we improve the PPO algorithm by setting the penalty factor to implement a strategy in which gold does not trade on non-trading days. Finally, with the proposed BiLSTM-PPO algorithm to learn the state vector composed of historical data, covariance and BiLSTM prediction results, we obtain the optimal trading strategy. A portfolio selection case is given to illustrate the application process and effectiveness of the method. We compare the BiLSTM-PPO with traditional PPO to prove the ef-fectiveness of it. Even in the worst case, the final income increases by 6.28% than the traditional PPO. And then, we compare the BiLSTM-PPO with five common investment de-cision algorithms such as Min-Variance, Deep Deterministic Policy Gradient, and etc by six financial metrics to prove the optimality of our model. The experimental results show that the BiLSTM-PPO achieves the highest final revenue and strategy provided by the algorithm is adjusted adaptively to ensure the maximization of returns.","PeriodicalId":405065,"journal":{"name":"2022 International Symposium on Intelligent Robotics and Systems (ISoIRS)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134080930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in the actual development process, the preference system in buildings is often destroyed by lightning strikes, and over time, this phenomenon does not decrease, but shows a rapid growth trend. At the present stage, China does not meet the strict lightning protection design requirements of high-rise buildings. Through the design and adjustment of BP neural layer, hidden layer and output layer, the BP neural network model of BP is established. According to the specific data of high-rise buildings and the judgment of relevant experts, the safety assessment samples including the lightning protection system, alarm system, safety evacuation system and management factors of high-rise buildings are collected. After 4 groups of 100 simulated lightning experiments in each group, the effective lightning detection rate of the optimized high-rise building signal lightning protection system based on GA-BP neural network is more than 90%, and the alarm time is about 3 times faster than the traditional lightning protection system, which perfectly meets the lightning protection needs of high-rise buildings.","PeriodicalId":405065,"journal":{"name":"2022 International Symposium on Intelligent Robotics and Systems (ISoIRS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133459966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is very important to quickly judge whether it is depression in today's society. In the work, the text dataset from social media is first vectorized with Bag-of-words and self-training Word2Vec, and then the text represented by Bag-of-words is trained and tested in different types of traditional machine learning classification methods. For text represented by Word2Vec, CNN and RNN algorithms are added for training. Finally, we compare and analyse the classification effects of traditional machine learning algorithms and deep learning algorithms with different text vectorization representations on text dataset, so as to find a better classification model of depression based on text dataset. The experimental results show that CNN and Logistic Regression model are better in the task of depression classification based on text dataset.","PeriodicalId":405065,"journal":{"name":"2022 International Symposium on Intelligent Robotics and Systems (ISoIRS)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131076389","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the superior nature of the recorded value, scholars from all walks of life have gradually gained a deeper understanding of it and promoted it to many fields, such as: computers, sports competition, human physiological limits and weather forecasting, etc. The results of these fields so far are inseparable from the contribution of recorded values.
