Build an Autoregressive and Moving Average Time Series Model
Welcome to time series analysis! We explore this project at a much deeper level to understand and predict the IoT sensor readings. It is mainly to investigate how the sensor data can be used to analyze through Moving Average and Autoregressive models. The models above can help us find hidden patterns and predict future readings.
Project Outcomes
Requirements:
- →Knowledge of time series analysis and some basic concepts, such as stationarity and autocorrelation.
- →Python and libraries including Pandas, NumPy, and Matplotlib.
- →Knowledge of machine learning models such as Moving Average (MA) and Autoregressive (AR) models.
- →Experience with model performance metric computation including Root Mean Squared Error (RMSE).
- →The knowledge on how to preprocess clean data to analyze time series data.
- →Visualization tools for time series, for example, autocorrelation plots and rolling averages.
- →An Augmented Dickey-Fuller (ADF) test for stationarity
Project Description
This project starts by cleaning and preparing the IoT sensor data so that we can analyze it. We then proceed to build many models: Moving Average models (MA(1), MA(2)) and then Autoregressive models (AR(1), AR(2), AR(3), AR(4)). Now that we have these models, we can understand the relationship between past and future values.
We then determine how well each model describes the predictions with Root Mean Squared Error (RMSE), a common way to gauge accuracy in forecasts. This makes things more insightful, so we bring in visualizations such as autocorrelation plots and rolling average plots. They help us see how sensor readings behave over time and how different models perform. By the end of this project, we will have a good idea of which model fits the data best and which one can confidently predict from historical sensor data.
