For this dataset  you have been tasked to perform EDA, apply feature engineering and do predictions of bad weather at any particular timestamp.\n** Bonus Points for using Ensemble Techniques**\n\nPredictions will be evaluated using the mean F1 score, calculated using the standard scikit-learn implementation.   \n\nIn addition to your predictions file (to be submitted here on Kaggle) which will indicate your leaderboard position, you're required to submit - \n- A detailed, well commented Python Notebook (hosted on Google Colab only, no .ipynb files will be accepted)\n- A very short report ( 300 words) describing your system\n- A short presentation ( ppt only) outlining your approach, feature engineering choices and the intuitions behind them.\n\nIn case there is any ambiguity, use your best guess and explain your assumptions clearly in your presentation. \n",

      "content": "\nThe evaluation metric for this competition is Mean F1-Score. The F1 score, commonly used in information retrieval, measures accuracy using the statistics precision ( \\text{p} ) and recall ( \\text{r} ).\n\nPrecision is the ratio of true positives (\\text{tp}) to all predicted positives (\\text{tp} + \\text{fp}). Recall is the ratio of true positives (\\text{tp}) to all actual positives (\\text{tp} + \\text{fn}). The F1 score is given by:\n\n[ \\text{F1} = 2\\frac{\\text{p} \\cdot \\text{r}}{\\text{p}+\\text{r}}\\ \\ \\mathrm{where}\\ \\ \\text{p} = \\frac{\\text{tp}}{\\text{tp}+\\text{fp}},\\ \\ \\text{r} = \\frac{\\text{tp}}{\\text{tp}+\\text{fn}} ]\n\nThe F1 metric weights recall and precision equally, and a good retrieval algorithm will maximize both precision and recall simultaneously. Thus, moderately good performance on both will be favored over extremely good performance on one and poor performance on the other.",
