2. Objective
Consolidate data required for PM2.5 Forecast
Find dominant features to predict Air Quality Index (AQI)

3. PM 2.5 – Domain Knowledge
Particulate Matter 2.5
Carbon particles of size equal or less than 2.5 x 106
Measured in
Responsible for severe health hazards
Can mix into blood and not easy to excrete
Source: Purlife

4. Magnitude
Source: MDPI

5. Mortality Map

6. Proposed Methodology

7. Data Sources
PM 2.5 – Berkeley Earth, Air4Thai
Other weather parameters – Weather Channel API (Collected data from Pathumwan
Demonstration School)
Timestamp of data: 2016– 19

8. Bangkok
Samutprakan
Narathiwat
Kanchanaburi
Rayong
Chiang Mai

9. Daily trend over years

10. Proposed Methodology
Support Vector Regression instead of linear regression
70% training and 30% testing
Justification of SVR using IRIS dataset

11. Feature Importance using Linear
Regression (Existing)

12. Feature Importance using SVR

13. Prediction Vs Actual Data in Linear
Regression

14. Prediction Vs Actual Data in SVR
