      "content": "On July 16, 1945 the first atomic bomb was exploded in the New Mexico desert. The explosion was massive and the equivalent to 18,000 tons of TNT. This bomb would change the world and could cause mass destruction and death. By this time, Germany had already surrendered and World War II in Europe was over. Japan was defeated as well, but would not surrender. The US was contemplating an invasion of Japan. Army leaders figured that anywhere from 500,000 to 1 million US and Allied soldiers would die in an invasion. You being President Truman decide to use the atom bombs in an effort to bring about Japan’s surrender in the Second World War. You know that Japan would not surrender easily thus devise a plan for the attack.\n\nOn August 6, 1945 an atomic bomb named Little Boy is on board Enola Gay which was piloted by Colonel Paul Tibbetts. Months of surveillance and reconnaissance operations, have led to the creation of a dataset, which is used to predict which city should be the target, given the constraints. Three cities are chosen as potential targets-1. Yokohama, 2. Hiroshima, 3. Kyoto.\n\nYou are provided with the dataset having all features. Your task is to predict which city should be targeted. The fate of the world is in your hands. Make your choices carefully. \n\n-train.csv is the training set\n-test.csv is the test set to submit your predictions\n-sample_submission.csv provides the format for submission.",

      "content": "<p>The evaluation pages describes how submissions will be scored and how students should format their submissions. You don't need a sub-title at the top (the page title appears above). For an example of a high quality evaluation page, see the 2013 KDD Cup page, which we have copied here:</p>\r\n<hr />\r\n<p>The evaluation metric for this competition is <a href=\"https://www.kaggle.com/wiki/MeanFScore\"> Mean F1-Score</a>. The F1 score, commonly used in information retrieval, measures accuracy using the statistics precision p and recall r. Precision is the ratio of true positives (tp) to all predicted positives (tp + fp). Recall is the ratio of true positives to all actual positives (tp + fn). The F1 score is given by:</p>\r\n<p>\\[ F1 = 2\\frac{p \\cdot r}{p+r}\\ \\ \\mathrm{where}\\ \\ p = \\frac{tp}{tp+fp},\\ \\ r = \\frac{tp}{tp+fn} \\]</p>\r\n<p>The 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.</p>\r\n<h2>Submission Format</h2>\r\n<p><strong>For every author in the dataset</strong>, submission files should contain two columns: AuthorId and DuplicateAuthorIds. DuplicateAuthorIds should be a space-delimited list. Every AuthorId counts as his/her own duplicate, and every duplicate should be listed under each of its respective ids. For example, if you suspect author A, B, and C are the same, you should list (A,A B C), (B,B A C), (C,C A B).</p>\r\n<p>The file should contain a header and have the following format:</p>\r\n<pre>AuthorId,DuplicateAuthorIds<br />1,1<br /><span style=\"font-size: 14px; line-height: 1.4em;\">8,8<br />9,9 10<br /></span><span style=\"font-size: 14px; line-height: 1.4em;\">10,10 9<br /></span><span style=\"font-size: 14px; line-height: 1.4em;\">etc.</span></pre>",
