EDMPoster/Intro

Master is giving positive examples:

ExamplePhone1
display
LCD
GSM
CPU
keyboard
ExamplePhone2
display
OLED
GSM
touchscreen
ExampleTablet1
display
AMOLED
HSPA
CPU 4
touchscreen

Master is giving negative examples:

negative

ExamplePhone3
display
LCD
GSM
CPU 4
keyboard

negative

ExampleTablet2
display
AMOLED
HSPA
CPU 4
keyboard

Luke builds an abstraction:

abstract AndroidDevice1
xor display
LCD
OLED
AMOLED
[ no keyboard ]
GSM
HSPA ?
CPU 1..4
xor input
keyboard
touchscreen

and a specialization:

abstract AndroidPhone : AndroidDevice
[ GSM ]
[ # CPU < 4 ]

Luke fixes the abstraction, since not all tablets have GSM:

abstract AndroidDevice
xor display
LCD
OLED
AMOLED
[ no keyboard ]
GSM ?
HSPA ?
CPU 1..4
xor input
keyboard
touchscreen

Luke validates the abstraction by generating examples and confirming with master:

AndroidPhone4 : AndroidPhone
display
AMOLED
GSM
HSPA
CPU 2
input
touchscreen

Luke discovers new variants and checks whether the positive ones are included and whether negative ones are excluded.
