Visual comparisons between actual and predicted values should be included.
Key Steps to Complete the Task:
- Identify a publicly available retail dataset that includes historical sales or demand information.
- Preprocess the data to ensure that it is suitable for time-series analysis, addressing any seasonality or trend issues.
- Select an appropriate forecasting model and implement it using Python.
- Assess the model performance using statistical metrics and visualizations to compare forecasted results against actual outcomes.
- Discuss potential improvements or alternative approaches in the context of retail data forecasting.
- Document every step, including rationales and challenges, in a well-organized DOC file.
Evaluation Criteria: Your submission will be evaluated based on the sophistication and appropriateness of the forecasting model, the clarity and effectiveness of your Python code, your evaluation strategy, and the detailed insights provided. A strong emphasis will be placed on how well you connect the modeling results to practical retail decision-making. This task sharpens your skills in predictive analytics, an essential competency for managing retail operations through data science.
Task Objective: This assignment is designed to enhance your skills in applying clustering techniques to perform customer segmentation. Your goal is to use relevant publicly available retail datasets related to customer behavior and purchase patterns to identify distinct customer groups, which can be instrumental in targeted marketing and improving customer service strategies.
