A general feature-weighting function for classification problems

作者:

Highlights:

• The salience of a feature can be changed given different queries.

• Multi-modal problems need a flexible weighting function to deal with modality.

• Proposing a differentiable, flexible, and general weighting function.

• The proposed is optimized for k-NN algorithm and assessed through experiments.

• The experiment results confirm the effectiveness of proposed weighting function.
