Data conventions

• In our data, the string "?" is used to denote a missing value.
• In our data, row one list the columns names. Those names define the various roles of our columns:

  • NUMeric column names start with an upper case letter. All other columns are SYMbolic.

  • Names ending with "+" or "-" are things we want to maximize or minimize(respectively).

  • Anything ending in "X" is a column we should ignore.

  • For example, here is some car data where the goals are Lbs-,Acc+,Mpg+; i.e. we want to minimize car weight and maximize our acceleration and maximize fuel consumption.

    {Clndrs  Volume  HpX      Model  origin  Lbs-  Acc+  Mpg+}
