Exploiting Universum data in AdaBoost using gradient descent

作者:

Highlights:

• We address a novel boosting algorithm by taking advantage of Universum data.

• A greedy, stagewise, functional gradient procedure is taken to derive the method.

• Explicit weighting schemes for labeled and Universum samples are provided.

• Practical conditions to verify effectiveness of Universum learning are described.

• This algorithm obtains superior performances over AdaBoost with Universum data.
