Computation
Time
Tree construction time ?
Need to include that?
Feature selection
99% of time
Time scalability with features
IFFS SW : linear x Wsize
IFFS : non linear and unfeasible
SFFS : linear
Is our algorhtm
better ?
Common
Ground
MAQC II set
MCC value comparable
Many samples
Contemporary
YES for
MCC mean
vlue
MCC value
Mean value across
endpoints
Metagenes
are useful?
Treelet/
Euclidean ?
Is the improvement
enough to compensate
for tree construcion?
PROS
-Resume of + genes
- Expanded feat space
- Interpretable comb.
-Common behaviour
NEW
ELEMENT?
Reliability
Score useful?
Score parameter
Include it in article?
Selection how?
Classifier
Transparent
Any other, only needed dist from boundary
LDA
Interpretable
Robust
Simple
NEW
ELEMENT!
More useful for
small sample number
After that is it totally
related with error rate?
gives more info
about data distribution
wrt classifier boundary
than ERROR RATE only
Microarray classification
overfit to train data
Infer data distribution
from train set
Many filter approaches
problem of univariate
feature selection
Few samples wrt gene number
