Task 2: Python-based Temperature Prediction (40 marks)

Objective

Using Python, predict future temperatures for selected countries based on historical data from long_format_annual_surface_temp.csv. This task will help you apply predictive modeling techniques to real-world data and validate your predictions against recent trends.

b. Data Cleaning: Handle any missing values or inconsistencies in the data. (4 marks)

c. Data Splitting: Split the data into training and testing sets (e.g., 80% training, 20% testing). (3 marks)

2.2 Model Building and Prediction (15 marks)

a. Model Selection: Initialize a suitable predictive model (e.g., linear regression, polynomial regression). (5 marks)

b. Model Training: Train the model using the training data. (5 marks)

c. Prediction: Predict future temperatures for the years 2023 to 2025 for at least five selected countries (e.g., China, USA, India, Brazil, Germany). (5 marks)

2.3 Model Evaluation (10 marks)

a. Performance Metrics: Evaluate the model's performance using appropriate metrics (e.g., Mean Squared Error, R-squared). (5 marks)

b. Visualization: Visualize the actual vs. predicted temperatures for the testing period. (5 marks)

2.4 Validation Against Real Data (5 marks)

a. Real Data Comparison: Compare your predicted temperatures with actual temperature data available for 2023-2024. (if available). (5 marks)

b. Error Analysis: Calculate and discuss the percentage error for each year. (5 marks)

Submission Format Instructions

The assignment must be typed, spell-checked, referenced, and submitted via Learning Mall Online to the correct dropbox.

Only electronic submissions are accepted - no hard copies:

l A Student_ID.pdf file contains a cover letter with your ID, and all the task report content.

l A Student_ID.zip file contains all the python script. and resource data.

All students must download their file and check that it is viewable after submission. Document uploads may become corrupted during the uploading process (e.g., due to slow internet connections). Therefore, students themselves are responsible for submitting a functional and correct file that needs to be tested after submitting it.
