It is difficult to establish accurate identification and prediction of the nonlinear plants that require dynamic modelling of the system. Extreme learning machine (ELM) as the recursive model due to its fast training and convergence speed is utilized in this work. However, its limitation is that it has only 1 hidden neuron which tends to make evolution speed low. Further, Multi-layer ELM (ML-ELM) model is applied on a nonlinear Auto-regressive complex benchmark system. The performance of ML-ELM is compared with dynamic recurrent functional link neural network (DRFLNN), functional link neural network (FLNN), nonlinear auto-regressive moving average (NARAX), multi-layer perception (MLP), radial basis function network (RBFN), Elman recurrent neural network (ERNN), and basic ELM models. From the comparison table, it can be seen that ML-ELM has better performance as compared with other models.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122909270","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}

The machine learning and artificial intelligence methods have been found to make this task more efficient and the advent of high throughput computes have proved to be beneficial in these tasks. In this work a hybrid LSTM-GRU network has been used for prediction of the adjusted closing price of the Standard & Poor 500 index. Also, the initial number of six features have been increased to 25 features by adding several technical indicators. The performance indicators like Return ratio, R2, MSE, Optimism and Pessimism ratios are used to compare the proposed model with stand-alone LSTM, GRU and MLP models. This comparison establishes that the proposed model is capable of more accurate prediction of the stock market prices.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123001970","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}

This study was based on the regulatory focus theory, mainly discussing the relationship among consumer goal orientation fits, the consumers’ product knowledge and advertising effects. In this study, 285 valid questionnaires were obtained. The results of the study showed that it has a better advertising effect in terms of the attitude toward advertising, attitude toward the brand, and purchase intention when the consumer goal orientation is the promotion focus, and the messages on advertising have promotion benefits. Moreover, when the consumer goal orientation fits the benefits of the advertising messages, and the consumers’ product knowledge is on the novice level, rather than expert level, consumers in the fit situation are more likely to have a better attitude toward advertising, attitude toward the brand and, purchase intention than in non-fit situations.","PeriodicalId":270059,"journal":{"name":"Journal of Statistics and Management Systems","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134476058","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}

The two sub-models namely- malaria only and COVID-19 only are also studied. The local stability of the disease-free equilibrium point of each sub-model and co-infection model is established. Existence of endemic equilibria for each sub-model is carried out. Moreover, we extend our co-infection model by incorporating six-time dependent controls.
