The crime prediction project leverages machine learning techniques to predict the likelihood of criminal activities in different geographical areas and times. By analyzing historical crime data, the system can identify patterns and trends, helping law enforcement agencies allocate resources more efficiently and potentially prevent crimes before they occur.
Objectives
Data Collection: Gather historical crime data from various sources such as police departments, government databases, and public records.
Data Preprocessing: Clean and preprocess the data to handle missing values, outliers, and inconsistencies. Transform the data into a suitable format for analysis.
Feature Selection: Identify and select relevant features that influence crime rates, such as location, time of day, day of the week, weather conditions, socio-economic factors, and more.
Model Selection: Choose appropriate machine learning algorithms to train the prediction models.
Model Training: Train the models using the preprocessed data and selected features.
Model Evaluation: Evaluate the models using appropriate metrics (e.g., accuracy, precision, recall, F1-score) to determine their performance.
Deployment: Deploy the best-performing model to a production environment where it can make real-time predictions.
Visualization: Develop dashboards and visualizations to present the predictions and insights to stakeholders.
