Based on the assumption that newer data are more important for predicting upcoming ratings, what TWR does is: weighing data based on time, and then using weighted data to build regression model for predicting upcoming ratings. In the experiments on a real-world TV ratings data set, it outperforms well-known time series models (e.g., Exponential Smoothing and ARIMA) and regression model (neural network).1954873 bytesapplication/pdf論文公開時間: 2015/3/16論文使用權限: 同意有償授權(權利金給回饋學校)時間序列預測電視收視率預測回歸time series predictionTV ratings predictionregressionthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/275594/1/ntu-104-R01922060-1.pdf
