There are 34 fields. The first 27 fields describe some kind of steel plate faults seen in images.  Unfortunately, there is no other information that I know of to describe these columns.

• X_Minimum

• X_Maximum

• Y_Minimum

• Y_Maximum

• Pixels_Areas

• X_Perimeter

• Y_Perimeter

• SumofLuminosity

• MinimumofLuminosity

• MaximumofLuminosity

• LengthofConveyer

• TypeOfSteel_A300

• TypeOfSteel_A400

• SteelPlateThickness

• Edges_Index

• Empty_Index

• Square_Index

• OutsideXIndex

• EdgesXIndex

• EdgesYIndex

• OutsideGlobalIndex

• LogOfAreas

• LogXIndex

• LogYIndex

• Orientation_Index

• Luminosity_Index

• SigmoidOfAreas

The last seven columns are one hot encoded classes, i.e. if the plate fault is classified as "Stains" there will be a 1 in that column and 0's in the other columns. If you are unfamiliar with one hot encoding, just know that the last seven columns are your class labels.

• Pastry

• Z_Scratch

• K_Scatch

• Stains

• Dirtiness

• Bumps

• Other_Faults
