SUMMARY: The project aims to construct a time series prediction model and document the end-to-end steps using a template. The Iron Production in Australia dataset is a univariate time series situation where we attempt to forecast future outcomes based on past data points.

INTRODUCTION: The problem is forecasting the monthly iron production in Australia. The dataset describes a time-series of weight (in thousand tons) over 40 years (1956-1995), and there are 476 observations. We used the first 80% of the observations for training and testing various models while holding back the remaining observations for validating the final model.

ANALYSIS: The baseline persistence model yielded an RMSE of 56.494. The MLP model processed the same test data with an RMSE of 41.415, which was better than the baseline model as expected. In an earlier ARIMA modeling experiment, the best ARIMA model with non-seasonal order of (1, 1, 1) and seasonal order of (1, 0, 1, 12) processed the validation data with an RMSE of 34.639.

CONCLUSION: For this dataset, the TensorFlow MLP model achieved an acceptable result, and we should consider using TensorFlow for further modeling.

SUMMARY: The project aims to construct a time series prediction model and document the end-to-end steps using a template. The USA Air Passenger Miles dataset is a univariate time series situation where we attempt to forecast future outcomes based on past data points.

ANALYSIS: The baseline persistence model yielded an RMSE of 1.581. The CNN-LSTM model processed the same test data with an RMSE of 1.109, which was better than the baseline model as expected. In an earlier ARIMA modeling experiment, the best ARIMA model with non-seasonal order of (1, 1, 2) and seasonal order of (1, 1, 1, 12) processed the validation data with an RMSE of 0.437.

CONCLUSION: For this dataset, the TensorFlow CNN-LSTM model achieved an acceptable result, and we should consider using TensorFlow for further modeling.

SUMMARY: The project aims to construct a time series prediction model and document the end-to-end steps using a template. The USA Housing Starts dataset is a univariate time series situation where we attempt to forecast future outcomes based on past data points.

INTRODUCTION: The problem is to forecast the monthly housing starts in the US. The dataset describes a time-series of housing sales over 11 years (1965-1975) in the US, and there are 132 monthly observations. We used the first 80% of the observations for training and testing various models, holding back the remaining observations to validate the final model.

ANALYSIS: The baseline persistence model yielded an RMSE of 28,010. The ConvLSTM model processed the same test data with an RMSE of 8,940, which was better than the baseline model as expected. In an earlier ARIMA modeling experiment, the best ARIMA model with non-seasonal order of (4, 0, 4) and seasonal order of (1, 0, 1, 12) processed the validation data with an RMSE of 6,276.

CONCLUSION: For this dataset, the TensorFlow ConvLSTM model achieved an acceptable result, and we should consider using TensorFlow for further modeling.

Dataset Used: U.S. Housing Starts 1965 – 1975.
