This project focuses on building a machine learning–based system to predict gold prices using historical market data. The objective was to apply an ensemble learning approach to capture complex price patterns and improve forecasting accuracy. By leveraging Random Forest Regression, the model successfully learned non-linear relationships between key market indicators such as Open, High, Low, and Volume to predict the Close price.
The project demonstrates how data-driven techniques can be applied to financial markets for better decision-making. It combines data preprocessing, exploratory analysis, model development, and performance evaluation into a complete end-to-end machine learning workflow.
🔍 Problem Statement
Gold prices are influenced by multiple economic and market factors, making accurate prediction challenging using traditional statistical methods. The aim of this project was to design a robust machine learning model that can analyze historical price data and generate reliable forecasts.
Key challenges addressed:
Handling noisy and inconsistent financial data
Capturing non-linear price movements
Avoiding overfitting
Ensuring model reliability on unseen data
🛠️ Approach & Methodology
The project followed a structured machine learning pipeline:
- Data Collection & Preparation
Historical gold price data was loaded and inspected for quality. Preprocessing steps included:
Removing duplicate records
Handling missing values
Converting date formats
Standardizing column names
Ensuring numerical consistency
This ensured that the dataset was clean, structured, and suitable for training a predictive model.
- Exploratory Data Analysis (EDA)
Time-series visualizations were created to understand gold price behavior. Insights observed:
Long-term upward trends during economic uncertainty
Short-term price fluctuations
Volatility clusters
Seasonal movement patterns
These patterns justified the use of machine learning for prediction.
- Model Development
A Random Forest Regressor was implemented using Scikit-learn. The dataset was split into:
80% Training data
20% Testing data
The model was trained to predict the Close price using market features.
- Performance Evaluation
Model performance was measured using:
R² Score: 0.89
MAE: $24.50
RMSE: $31.75
These results indicate strong predictive accuracy and reliable generalization.
📈 Key Results & Insights
