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

|
|
Real-Valued Attributes. In Proceedings of the CSCSI (Canadian
|
|
AI) Conference.
|
|
-- Results:
|
|
-- instance-based prediction of relative cpu performance
|
|
-- similar results; no transformations required
|
|
- 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)
|
|
|
|
