Dataset Information

For what purpose was the dataset created?

Inspired by the Mushroom Data Set of J. Schlimmer: url:https://archive.ics.uci.edu/ml/datasets/Mushroom.

Additional Information

The given information is about the Secondary Mushroom Dataset, the Primary Mushroom Dataset used for the simulation and the respective metadata can be found in the zip. This dataset includes 61069 hypothetical mushrooms with caps based on 173 species (353 mushrooms per species). Each mushroom is identified as definitely edible, definitely poisonous, or of unknown edibility and not recommended (the latter class was combined with the poisonous class). The related Python project contains a Python module secondary_data_generation.py used to generate this data based on primary_data_edited.csv also found in the repository. Both nominal and metrical variables are a result of randomization. The simulated and ordered by species version is found in secondary_data_generated.csv. The randomly shuffled version is found in secondary_data_shuffled.csv.

Variable Information

One binary class divided in edible=e and poisonous=p (with the latter one also containing mushrooms of unknown edibility). Twenty remaining variables (n: nominal, m: metrical) 1. cap-diameter (m): float number in cm 2. cap-shape (n): bell=b, conical=c, convex=x, flat=f, sunken=s, spherical=p, others=o 3. cap-surface (n): fibrous=i, grooves=g, scaly=y, smooth=s, shiny=h, leathery=l, silky=k, sticky=t, wrinkled=w, fleshy=e 4. cap-color (n): brown=n, buff=b, gray=g, green=r, pink=p, purple=u, red=e, white=w, yellow=y, blue=l, orange=o, black=k 5. does-bruise-bleed (n): bruises-or-bleeding=t,no=f 6. gill-attachment (n): adnate=a, adnexed=x, decurrent=d, free=e, sinuate=s, pores=p, none=f, unknown=? 7. gill-spacing (n): close=c, distant=d, none=f 8. gill-color (n): see cap-color + none=f 9. stem-height (m): float number in cm 10. stem-width (m): float number in mm 11. stem-root (n): bulbous=b, swollen=s, club=c, cup=u, equal=e, rhizomorphs=z, rooted=r 12. stem-surface (n): see cap-surface + none=f 13. stem-color (n): see cap-color + none=f 14. veil-type (n): partial=p, universal=u 15. veil-color (n): see cap-color + none=f 16. has-ring (n): ring=t, none=f 17. ring-type (n): cobwebby=c, evanescent=e, flaring=r, grooved=g, large=l, pendant=p, sheathing=s, zone=z, scaly=y, movable=m, none=f, unknown=? 18. spore-print-color (n): see cap color 19. habitat (n): grasses=g, leaves=l, meadows=m, paths=p, heaths=h, urban=u, waste=w, woods=d 20. season (n): spring=s, summer=u, autumn=a, winter=w
