Project Objectives
Time Series Forecasting
Our primary goal is to develop precise forecasting models specifically tailored for sales data. By embracing time-series analysis, we aim to capture the intricate patterns and trends inherent in sales data.
Model Evaluation
To ensure the reliability of our predictions, we implement rigorous model evaluation techniques. This involves scrutinizing the performance of various forecasting models to select the most effective one.
Database Integration
The seamless integration of our forecasting results into a PostgreSQL database is crucial for easy accessibility. This integration enhances the structured storage of valuable insights, making them readily available for strategic decision-making.
SageMaker Inference Model Deployment
Adding a layer of sophistication to our project, we leverage Amazon SageMaker for deploying machine learning models. This not only automates the deployment process but also enhances the agility and responsiveness of our forecasting system.
Technical Overview
Database Connection
Our journey begins with a secure connection to a PostgreSQL database on Amazon RDS. The use of industry-standard encryption protocols ensures the confidentiality and integrity of our data.
Data Retrieval and Preprocessing
The foundation of accurate forecasting lies in robust data preprocessing. Rigorous cleaning, transformation, and handling of missing values set the stage for a high-quality dataset. Temporal indexing further enhances our analyses, making them time-aware and reflective of dynamic trends.
Forecasting Models
We employ a trifecta of powerful forecasting models:
- Auto ARIMA: An automated version of the ARIMA model, fine-tuned for optimal performance.
- SARIMA: Seasonal ARIMA models enhance accuracy by considering seasonality in our sales data.
- Exponential Smoothing: Leveraging the Stats Models library, we apply exponential smoothing with additive seasonality, ensuring robust forecasting capabilities with competitive Mean Absolute Percentage Error (MAPE) values.
The selection of the most effective model is based on a comprehensive model comparison and evaluation.
