Temperature prediction is an important and significant step for monitoring global warming and the environment to save and protect human lives. The climatology parameters such as temperature, pressure, and wind speed are time-series data and are well predicted with data driven models. However, data-driven models have certain constraints, due to which these models are unable to predict the missing values and erroneous data caused by factors like sensor failure and natural disasters. In order to solve this issue, an efficient hybrid model, i.e., attention-based bidirectional long short term memory temporal convolution network (ABTCN) architecture is proposed. ABTCN uses k-nearest neighbor (KNN) imputation method for handling the missing data. A bidirectional long short term memory (Bi-LSTM) network with self-attention mechanism and temporal convolutional network (TCN) model that aids in the extraction of features from complex data and prediction of long data sequence. The performance of the proposed model is evaluated in comparison to various state-of-the-art deep learning models using error metrics such as MAE, MSE, RMSE, and R score. It is observed that our proposed model is superior over other models with high accuracy.
温度预测是监测全球变暖与环境的重要步骤,有助于拯救和保护人类生命。气候参数(如温度、压力和风速)是时间序列数据,可通过数据驱动模型进行很好的预测。然而,数据驱动模型存在一定的局限性,这些模型无法预测因传感器故障和自然灾害等因素导致的缺失值和错误数据。为了解决这个问题,提出了一种高效的混合模型,即基于注意力的双向长短时记忆时间卷积网络(ABTCN)架构。ABTCN 使用 K 最近邻(KNN)插补方法来处理缺失数据。双向长短时记忆(Bi-LSTM)网络带有自注意力机制和时间卷积网络(TCN)模型,有助于从复杂数据中提取特征并预测长数据序列。使用平均绝对误差(MAE)、均方误差(MSE)、均方根误差(RMSE)和 R 分数等误差指标,将所提出的模型与各种最先进的深度学习模型进行比较,评估其性能。结果表明,与其他模型相比,我们提出的模型具有更高的准确性。
