  1. Title: Relative CPU Performance Data

  2. Source Information -- Creators: Phillip Ein-Dor and Jacob Feldmesser -- Ein-Dor: Faculty of Management; Tel Aviv University; Ramat-Aviv; Tel Aviv, 69978; Israel -- Donor: David W. Aha (aha@ics.uci.edu) (714) 856-8779
    -- Date: October, 1987

  3. Past Usage:

    1. Ein-Dor and Feldmesser (CACM 4/87, pp 308-317) -- Results: -- linear regression prediction of relative cpu performance -- Recorded 34% average deviation from actual values
    2. Kibler,D. & Aha,D. (1988). Instance-Based Prediction of Real-Valued Attributes. In Proceedings of the CSCSI (Canadian AI) Conference. -- Results: -- instance-based prediction of relative cpu performance -- similar results; no transformations required
    3. Predicted attribute: cpu relative performance (numeric)
  4. Relevant Information: -- The estimated relative performance values were estimated by the authors using a linear regression method. See their article (pp 308-313) for more details on how the relative performance values were set.

  5. Number of Instances: 209

  6. Number of Attributes: 10 (6 predictive attributes, 2 non-predictive, 1 goal field, and the linear regression's guess)

  7. Attribute Information:

  8. vendor name: 30 (adviser, amdahl,apollo, basf, bti, burroughs, c.r.d, cambex, cdc, dec, dg, formation, four-phase, gould, honeywell, hp, ibm, ipl, magnuson, microdata, nas, ncr, nixdorf, perkin-elmer, prime, siemens, sperry, sratus, wang)

  9. Model Name: many unique symbols

  10. MYCT: machine cycle time in nanoseconds (integer)

  11. MMIN: minimum main memory in kilobytes (integer)

  12. MMAX: maximum main memory in kilobytes (integer)

  13. CACH: cache memory in kilobytes (integer)

  14. CHMIN: minimum channels in units (integer)

  15. CHMAX: maximum channels in units (integer)

  16. PRP: published relative performance (integer)

  17. ERP: estimated relative performance from the original article (integer)

  18. Missing Attribute Values: None

  19. Class Distribution: the class value (PRP) is continuously valued. PRP Value Range: Number of Instances in Range: 0-20 31 21-100 121 101-200 27 201-300 13 301-400 7 401-500 4 501-600 2 above 600 4
