The Dice coefficient can be used to compare the pixel-wise agreement between a predicted segmentation and its corresponding ground truth. The formula is given by:</p>\n\n$$  \\dfrac{ 2 \\  \\cdot  \\mid \\mathrm{X} \\cap \\mathrm{Y} \\  \\mid }{ \\mid \\  \\mathrm{X} \\mid + \\mid \\mathrm{Y} \\  \\mid } $$\n\n<p>where X is the predicted set of pixels and Y is the ground truth. The Dice coefficient is defined to be 1 when both X and Y are empty. The leaderboard score is the mean of the Dice coefficients for each image in the test set.</p>\n\n\n\n<h2>Submission Format</h2>\n<p> In order to reduce the submission file size, our metric uses run-length encoding on the pixel values.  Instead of submitting an exhaustive list of indices for your segmentation, you will submit pairs of values that contain a start position and a run length. E.g. '1 3' implies starting at pixel 1 and running a total of 3 pixels (1,2,3). </p>\n\n<pre>encode,pixel_value\n0u7or1fr6v6sblk1mrahwaz9xeuro7p4,0 1\n0n7lp2tldbk94mij1752t75tlc3h0pnl,0 1\nn2ds2ett5lj2bxy9xm44zhrvsrl3xqss,0 1\n...</pre>",
