After a month of making scientific observations and taking careful measurements, we’ve determined that 900 ghouls, ghosts, and goblins are infesting our halls and frightening our data scientists. When trying garlic, asking politely, and using reverse psychology didn't work, it became clear that machine learning is the only answer to banishing our unwanted guests.</p>\r\n<p><img src=\"https://storage.googleapis.com/kaggle-media/competitions/kaggle/5708/media/halloween-660x.png\" alt=\"\" width=\"660\" height=\"140\" /></p>\r\n<p>So now the hour has come to put the data we’ve collected in your hands. We’ve managed to identify 371 of the ghastly creatures, but need your help to vanquish the rest. And only an accurate classification algorithm can thwart them. Use bone length measurements, severity of rot, extent of soullessness, and other characteristics to distinguish (and extinguish) the intruders. Are you ghost-busters up for the challenge?</p>",
