With the development of Internet and computer science, computer network is changing people’s lives. Meanwhile, Network traffic prediction model itself becomes more and more complex. It is an important research direction to quickly and accurately detect the intrusions or attacks. The performance efficiency of a network intrusion detection system is dominated by pattern matching algorithm. Howeve...

To investigate the variability in energy output from a network of photo-voltaic cells, solar radiation was recorded at ten sites every ten minutes in the Pentland Hills to the south of Edinburgh. We identify spatio-temporal auto-regressive moving average (STARMA) models as the most appropriate to address this problem. Although previously considered computationally prohibitive to work with, we s...

Background: In India, the dairy business is expanding dramatically. Tamil Nadu milk cooperatives significantly contribute to growth of sector in state. terms delivering economic income for smallholders and satisfying customer demand, identification production one primary financial operations made India. Considering this, it crucial understand future enhance sustain sector’s development. Methods...

The increasing demand for clean energy and the global shift towards renewable sources necessitate reliable solar radiation forecasting effective integration of into system. Reliable has become crucial design, planning, operational management systems, especially in context ambitious greenhouse gas emission goals. This paper presents a study on application auto-regressive integrated moving averag...

Finansal verilerin en dikkate değer özelliklerinden biri zamana bağlı biçimde bir dizi teşkil etmeleridir. Bundan ötürü zaman serilerinin unsurları, söz konusu ifade ettiği ekonomik ve finansal parametreler hakkındaki bilgiyi de kapsamaktadır. Finans çalışmalarında değişkenlere ilişkin öngörü ya da tahmin hayati öneme sahiptir. değişkenlerin doğru, sağlıklı edilebilmesi, piyasalardaki paydaşlar...

The integration of renewable energy resources into smart grids has become increasingly important to address the challenges managing and forecasting production in fourth revolution. To this end, artificial intelligence (AI) emerged as a powerful tool for improving control management. This study investigates application machine learning techniques, specifically ARIMA (auto-regressive integrated m...

In this paper we consider the problem of testing for parameter changes in ARIMA models based on the cusum test. The proposed test procedure is applicable to testing for the change from stationary models to nonstationary models, and vice versa. The idea is to transform the time series via differencing to make the whole time series as a combination of stationary subseries. For this task, we propo...

We propose diagnostics for ARIMA model fitting for time series formed by deleting observations from the data and measuring the change in the estimates of the parameters. The use of leave-one-out diagnostics is a well established tool in regression analysis. We demonstrate the efficacy of observation deletion based diagnostics for ARIMA models, addressing issues special to the time diagnostics b...

To scientifically predict the future energy demand of Shandong province, this study chose the past energy demand of Shandong province during 1995–2015 as the research object. Based on building model data sequences, the GM-ARIMA model, the GM (1,1) model, and the ARIMA model were used to predict the energy demand of Shandong province for the 2005–2015 data, the results of which were then compare...
