The testing data contains a set of 330 policy portfolios, each having at least 1,000 auto policies.\n\nThe training data contains of a set of auto policies including a number of policy level attributes as well as Annual Premium and Loss Amount.\n\nThe Loss Ratio of a policy is just the Loss Amount divided by the Premium.\n\nThe Loss Ratio of a portfolio of policies is the sum of all the Loss Amounts of all the policies in the portfolio divided by the sum of all the Premiums in the portfolio.\n\nYour target is the natural logarithm of the the loss Ratio of a portfolio.\n\n## Implementation\n\nPredict the loss ratio of a set of insurance policy portfolios. \n(ITCS-6100 Big Data Analytics - https://www.kaggle.com/c/lossratio/overview)\n\n- Calculated impact of each feature on loss amount and performed through Exploratory Data Analysis using Matplotlib \u0026 Seaborn to select important features for modelling.\n- Implemented rigorous feature engineering by grouping multiple policies into portfolio and creating useful features using aggregation which improved MAE by 0.90 and accuracy by 40%\n\n### Exploratory Data Analysis \u0026 Prediction\n- [EDA Notebook 1](https://github.com/adityakamble49/loss-ratio-prediction/blob/master/notebooks/eda/eda-1.ipynb)\n- [EDA Notebook 2](https://github.com/adityakamble49/loss-ratio-prediction/blob/master/notebooks/eda/eda-2.ipynb)\n- [Prediction Notebook](https://github.com/adityakamble49/loss-ratio-prediction/blob/master/notebooks/prediction/loss-ratio-prediction-notebook.ipynb)\n\n## Presentation\n\n[![Loss Ratio Prediction - Video Presentation](https://res.cloudinary.com/marcomontalbano/image/upload/v1590527549/video_to_markdown/images/youtube--OWiOLAGfRWA-c05b58ac6eb4c4700831b2b3070cd403.jpg)](https://www.youtube.com/watch?v=OWiOLAGfRWA \"Loss Ratio Prediction - Video Presentation\")\n\n## Results\n![Kaggle Leaderboard](results/kaggle-leaderboard.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fadityakamble49%2Floss-ratio-prediction","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fadityakamble49%2Floss-ratio-prediction","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fadityakamble49%2Floss-ratio-prediction/lists"}
