## Introduction: StockSense—Solving Inventory Management Challenges for SMEs with Machine Learning

StockSense is an open-source project developed by IssaMuiz, released on GitHub (link: https://github.com/IssaMuiz/StockSense, release date: May 23, 2026). It is a lightweight inventory forecasting tool based on Random Forest Regression that helps SMEs analyze historical sales data, predict product demand, generate replenishment recommendations, reduce stockouts and overstock issues, and promote data-driven decision-making. The tool uses Streamlit to build its interface, lowering the barrier to use for non-technical users.

## Project Background: Pain Points in Inventory Management for SMEs

SMEs face two major challenges in inventory management: excessive inventory ties up cash flow and storage space, while insufficient inventory leads to stockouts and missed sales opportunities. Traditional experience-based management struggles to handle demand fluctuations, and StockSense is an open-source ML tool created to address this pain point.

## Core Features and Design Philosophy

The design goal of StockSense is to enable SMEs to easily implement data-driven inventory decisions. Its core features include:
1. CSV Data Upload: Supports users to upload their own sales data;
2. Sales Insights and EDA: Automatically analyzes data features and trends;
3. Demand Forecasting: Predicts future sales volume for each product;
4. Replenishment Recommendation Engine: Provides specific replenishment quantities based on forecasts;
5. Lightweight Interface: Built with Streamlit, no complex deployment required.

## Technical Implementation: Data Processing and Model Training

### Data Processing
A synthetic dataset of 901 rows and 9 columns (simulating supermarket inventory sales from January to June 2024) was used. Preprocessing steps: remove irrelevant columns, convert dates to datetime format, handle duplicates/empty values, sort by date and product ID, check for negative values, add lag features. Finally, 895 rows and 7 columns of data were obtained, divided into training set (626 rows), validation set (134 rows), and test set (135 rows).
### Model Selection
RandomForestRegressor was adopted for the following reasons: handles non-linear relationships, is insensitive to feature scaling, has strong interpretability, and is stable on small datasets. Feature engineering: remove product names (retain ID encoding), experimentally select features (e.g., day-of-week feature improves performance).

## Model Performance and Experimental Insights

### Performance Evaluation
Metrics after GridSearchCV tuning:
| Metric | Score |
|--------|-------|
| MAE | 2.66 |
| MSE |11.47|
| R² |-0.006|
Although the R² is close to zero, the MVP prototype on synthetic data has an error of about 3 units, which has practical value.
### Experimental Insights
- The 7-day rolling average feature increased MAE from 2.81 to 2.98 (performance degradation);
- The day-of-week feature reduced MAE to 2.75 (performance improvement), indicating that feature engineering requires experimental validation.

## Applicable Scenarios and Practical Value

StockSense is suitable for:
1. Small retailers: No professional data team, need ready-to-use tools;
2. Startup e-commerce businesses: Simple operations, regular sales data;
3. Inventory optimization beginners: Understand the application of ML in inventory management.
Its value lies in solving practical problems with simple technology and providing a lightweight solution for SMEs with limited budgets.

## Future Improvement Directions

Future improvement directions:
1. Introduce more lag features and rolling statistics;
2. Add seasonal features (months, holidays);
3. Integrate external signals (promotions, weather);
4. Train the model using larger-scale real datasets.
The aim is to enhance the model's ability to adapt to dynamic changes in real business environments.
