Short Term Forecasting 短期预测 - The accurate short-term forecasting of power outputs is essential to the extensive integration of wind generation into power grids. [1] Short-term forecasting provides predictions up to 7 days ahead. [2] Due to time requirements for developing a COVID-19 vaccine, evidence is needed to inform short-term forecasting method selection at county, health district, and state levels. [3] Conclusion Due to limited data availability during the ongoing pandemic, less data-hungry short-term forecasting models, like ARIMA and ETS, can help in anticipating the future outbreaks of SARS-CoV2. [4] In this paper, the short-term forecasting of landslides (STFL) model is proposed by analyzing landslide deformation characteristics in a known evolution process. [5] For a long time, market forecasting of the construction machinery is regarded as short-term forecasting, which lacks the analysis of macro-marketing law and cannot reflect the true law of market development. [6] Stimulated by current developments in deep learning (DL) techniques as well as the promising efficiency in energy-related applications, this study introduces a novel DL architecture, called PV-Net, for short-term forecasting of day-ahead PV energy. [7] It is, thus, considered to be appropriate for use in short-term forecasting over large areas. [8] The proposed neural network technology for predicting TS yield levels using a pre-forecast autocorrelation analysis of retrospective levels reduces the error of short-term forecasting of grain yield in the arid natural and climatic conditions of the Lower Volga region. [9] Emphasis is placed on the fact that adaptive models based on ostentatious smoothing of time series should be used to optimize the logistics flows of the organization as the main tool for short-term forecasting. [10] The method can also be used for other kinds of short-term forecasting. [11] This study proposes a novel approach of using genetically optimized non-linear auto-regressive recurrent neural networks (NARX) for ultra-short-term forecasting of PV power output. [12] The performance of load forecast for Long Island region taking GT and weather data as input variables is compared with that taking only weather data as input variables, which shows that the introduction of GT improves short-term forecasting effectiveness significantly. [13] Due to the impact of many local sudden changes in photovoltaic (PV) output power, its ultra-short-term forecasting is facing great challenges. [14] With the growing dependence on wind power generation, improving the accuracy of short-term forecasting has become increasingly important for ensuring continued economical and reliable system operations. [15] Our result shows that the Conv-LSTM neutral network can train the model with a reasonable output and is suitable for short-term forecasting network ride-hailing demand forecast with spatiotemporal feature information. [16] The model was benchmarked against Prophet and a seasonal naive model, showing that the current model is much more skillful and reliable in very short-term forecasting. [17] Accurate short-term forecasting of photovoltaic (PV) power is indispensable for controlling and designing smart energy management systems for microgrids. [18] Accurate short-term forecasting of solar radiation can ensure the safety of photovoltaic grids and improve the utilization efficiency of the solar energy systems. [19] In addition, based on the forecasting results of the VAR (1)-GARCH (1,1) model, it shows that this model is good for short-term forecasting. [20] In this study, the performance of lightning data assimilation is evaluated in the short-term forecasting of a moderate precipitation event along the western margin of the Junggar Basin and eastern Jayer Mountain. [21] This paper proposes a new model for short-term forecasting power generation capacity of large-scale solar power plant (SPP) in Vietnam considering the fluctuations of weather factors when applying the Long Short-Term Memory networks (LSTM) algorithm. [22] This paper focused on short-term forecasting of high-frequency global horizontal irradiance data from one of South Africa’s radiometric stations. [23] Here we report insights from ten weeks of collaborative short-term forecasting of COVID-19 in Germany and Poland (12 October–19 December 2020). [24] Nowcasting, or the short-term forecasting of precipitation, is urgently needed to support the mitigation circle in hydrometeorological disasters. [25] Implications for coupled data assimilation and short-term forecasting are discussed. [26] Short-term forecasting of the gross product of the regional economy is carried out using a production function that provides a better approximation of retrospective data of the time interval of the previous forecasting year. [27] The paper presents a developed methodology of short-term forecasting for heat production in combined heat and power (CHP) plants using a big data-driven model. [28] Introduction: The novel coronavirus (COVID-19) has significantly spread over the world and impacted with new challenges to the research community Although governments initiated numerous containment and social distancing measures all over the world, the need for healthcare resources has dramatically increased and the effective management of infected patients becomes a challenging task for healthcare centres Objective: Thus, the objective of the research is to find the accurate short-term forecasting of the number of new confirmed covid-19 positive cases is important for optimizing the available resources and slowing down the progression of COVID-19 Recently, various methods like machine learning models and other algorithms demonstrated important improvements when handling time-series data in various applications Methods: This paper presents a comparative study of different machine learning methods and models to forecast the number of new cases Specifically, Long short-term memory (LSTM), Autoregressive Integrated Moving Average (ARIMA), Holt’s Linear forecasting model, Exponential smoothing and Moving-average model algorithms have been applied for forecasting of COVID-19 cases based on data set Result: Results were analysed using various parameters like Root Mean Square Error, Mean Absolute Error, Mean Absolute Percentage Error, Error Vector Magnitude Root Mean Square Logarithmic Error Conclusion: As a conclusion, compared to other models, Long Short TermModel predicted better forecasting and gives the best performance in terms of different parameters © IJCRR. [29] Short-term forecasting methods can be roughly classified into physics-based modelling and data-based modelling. [30] Two proposed time series decomposition methods are developed for short-term forecasting of the CO2 emissions of electricity. [31] Firstly, based on the strong correlation between PWV_Met and ZTD hourly sequences from the International GNSS Service Network’s BJFS station for DOYS 182-212, 2015, the results of experiment prove that the reliability of GNSS ZTD is used to forecast PWV_Met in short-term forecasting. [32] The natural gas energy prediction results show that this method has high prediction accuracy compared with other methods, which means that the method proposed in this paper can be used as an effective tool for short-term forecasting of natural gas production in the United States and play an auxiliary role in energy forecasting. [33] Short-term forecasting is often used to predict with calculations using time, hour, day or week. [34] The paper considers short-term forecasting of the intensity of solar radiation in the city of Odessa based on an artificial neural network. [35] long-short-term memory and recurrent neural networks combination is formulated for very short-term forecasting of wind speed and solar radiation. [36] Accurate short-term forecasting is thus vital to support country-level policy making. [37] In view of the fact that the existing ultra-short-term forecasting method of wind power is difficult to effectively mine and analyse the inherent variation law of data, a forecasting method of wind power based on wavelet decomposition combined with bi- directional long-short term memory neural network (W-BiLSTM) is proposed. [38] Thus, short-term forecasting has crucial utility for generating dispatching commands, managing the spot market, and detecting anomalies. [39] The article considers a variant of inclusion of a neural network into the microwave radiometric system of remote sensing of the atmosphere to perform short-term forecasting of meteorological parameters, based on current measurements of power of own radio-thermal emission of the atmosphere in three frequency bands. [40] The inefficiency of short-term forecasting of strong earthquakes is obvious. [41] Furthermore, we conduct additional experiments on two other cryptocurrencies, Ethereum and Litecoin, to further confirm the effectiveness of the MRCLSTM in short-term forecasting for multivariate time series of cryptocurrencies. [42] According to the predicted time span, the power load forecasting problem can be roughly divided into long-term and short-term forecasting. [43] In this study, the soft computing method is used for short-term forecasting of agriculture commodity price based on time series data using the artificial neural network (ANN). [44] Two short-term forecasting models based on non-parametric kernel density estimation (KDE) and mixture density networks (MDN) are developed that estimate the conditional probability of the customers' aggregate demand at any given temperature and time. [45] The first approach is physically based and adapts the solar short-term forecasting approach referred to as “smart-persistence” to wind power forecasting. [46] This paper presents the tracking and short-term forecasting of mesoscale convective cloud clusters (CCs) that occurred over southeast Brazil and the adjacent Atlantic Ocean during 2009–17. [47] This article intends to provide short-term forecasting of WWTP energy consumption based on data-driven soft sensors using traditional time-series and deep learning methods. [48] The time series model with polynomial smoothing is used for short-term forecasting that allows analysing the dynamics of passenger traffic, decreasing costs on monitoring of information on passenger traffic and allows using results for solving tasks of technological organization of public transport. [49] In contrast to short-term forecasting, it is often a onetime exercise and forecasts are rarely generated continuously.
