with Automatic Rule Generalization. Recent Advances in Computers,
Computing and Communications, pp.296-300, WSEAS Press, 2002.
- Note: This was a slightly different dataset that had more
classes, and was considerably more difficult.
- Predictive attribute: Poker Hand (labeled <20>class<73>)
- Found to be a challenging dataset for classification algorithms
- Relational learners have an advantage for some classes
- The ability to learn high level constructs has an advantage
4. Relevant Information:
Each record is an example of a hand consisting of five playing
cards drawn from a standard deck of 52. Each card is described
using two attributes (suit and rank), for a total of 10 predictive
attributes. There is one Class attribute that describes the
<20>Poker Hand<6E>. The order of cards is important, which is why there
are 480 possible Royal Flush hands as compared to 4 (one for each
suit <20> explained in more detail below).
5. Number of Instances: 25010 training, 1,000,000 testing
6. Number of Attributes: 10 predictive attributes, 1 goal attribute
7. Attribute Information:
1) S1 <20>Suit of card #1<>
Ordinal (1-4) representing {Hearts, Spades, Diamonds, Clubs}
2) C1 <20>Rank of card #1<>
Numerical (1-13) representing (Ace, 2, 3, ... , Queen, King)
3) S2 <20>Suit of card #2<>
Ordinal (1-4) representing {Hearts, Spades, Diamonds, Clubs}
4) C2 <20>Rank of card #2<>
Numerical (1-13) representing (Ace, 2, 3, ... , Queen, King)
5) S3 <20>Suit of card #3<>
Ordinal (1-4) representing {Hearts, Spades, Diamonds, Clubs}
6) C3 <20>Rank of card #3<>
Numerical (1-13) representing (Ace, 2, 3, ... , Queen, King)
7) S4 <20>Suit of card #4<>
Ordinal (1-4) representing {Hearts, Spades, Diamonds, Clubs}
8) C4 <20>Rank of card #4<>
Numerical (1-13) representing (Ace, 2, 3, ... , Queen, King)
9) S5 <20>Suit of card #5<>
Ordinal (1-4) representing {Hearts, Spades, Diamonds, Clubs}
10) C5 <20>Rank of card 5<>
Numerical (1-13) representing (Ace, 2, 3, ... , Queen, King)
11) CLASS <20>Poker Hand<6E>
Ordinal (0-9)
0: Nothing in hand; not a recognized poker hand
1: One pair; one pair of equal ranks within five cards
2: Two pairs; two pairs of equal ranks within five cards
3: Three of a kind; three equal ranks within five cards
4: Straight; five cards, sequentially ranked with no gaps
5: Flush; five cards with the same suit
6: Full house; pair + different rank three of a kind
7: Four of a kind; four equal ranks within five cards
8: Straight flush; straight + flush
9: Royal flush; {Ace, King, Queen, Jack, Ten} + flush
8. Missing Attribute Values: None
9. Class Distribution:
The first percentage in parenthesis is the representation
within the training set. The second is the probability in the full domain.
Training set:
0: Nothing in hand, 12493 instances (49.95202% / 50.117739%)
1: One pair, 10599 instances, (42.37905% / 42.256903%)
2: Two pairs, 1206 instances, (4.82207% / 4.753902%)
3: Three of a kind, 513 instances, (2.05118% / 2.112845%)
4: Straight, 93 instances, (0.37185% / 0.392465%)
5: Flush, 54 instances, (0.21591% / 0.19654%)
6: Full house, 36 instances, (0.14394% / 0.144058%)
7: Four of a kind, 6 instances, (0.02399% / 0.02401%)
8: Straight flush, 5 instances, (0.01999% / 0.001385%)
9: Royal flush, 5 instances, (0.01999% / 0.000154%)
The Straight flush and Royal flush hands are not as representative of
the true domain because they have been over-sampled. The Straight flush
is 14.43 times more likely to occur in the training set, while the
Royal flush is 129.82 times more likely.
Total of 25010 instances in a domain of 311,875,200.
Testing set:
The value inside parenthesis indicates the representation within the test
set as compared to the entire domain. 1.0 would be perfect representation,
while <1.0 are under-represented and >1.0 are over-represented.
0: Nothing in hand, 501209 instances,(1.000063)
1: One pair, 422498 instances,(0.999832)
2: Two pairs, 47622 instances, (1.001746)
3: Three of a kind, 21121 instances, (0.999647)
4: Straight, 3885 instances, (0.989897)
5: Flush, 1996 instances, (1.015569)
6: Full house, 1424 instances, (0.988491)
7: Four of a kind, 230 instances, (0.957934)
8: Straight flush, 12 instances, (0.866426)
9: Royal flush, 3 instances, (1.948052)
Total of one million instances in a domain of 311,875,200.
