¿Cuál es el precio del diamante 💎?

Primera competición dentro de Ironhack para ver quien se aproximaba más al valor real. La base de datos consistia en:

  • data.csv: training set (Para entrenar nuestro modelo)
  • test.csv: test set (Para hacer predicciones)

las Features:

  • id: only for test & sample submission files, id for prediction sample identification
  • price: price in USD
  • carat: weight of the diamond
  • cut: quality of the cut (Fair, Good, Very Good, Premium, Ideal)
  • color: diamond colour, from J (worst) to D (best)
  • clarity: a measurement of how clear the diamond is (I1 (worst), SI2, SI1, VS2, VS1, VVS2, VVS1, IF (best))
  • x: length in mm
  • y: width in mm
  • z: depth in mm
  • depth: total depth percentage = z / mean(x, y) = 2 * z / (x + y) Valores:(43--79)
  • table: width of top of diamond relative to widest point Valores:(43--95)

Resolución:

Aplicación del modelo random forest, tras el analisis inicial de la base de datos.

NOTA: Al eliminar los datos atípicos el modelo mejora las predicciones dentro del código pero al pasarlo a Kaggle empeora los mismos.
