| Abstract(in English) | We propose a new method for adaptive group testing. A non-adaptive group testing based on boolean compressive sensing has been proposed. The conventional method improves the estimation performance by using a sparsity constraint. However, the conventional method is a method of non-adaptive group testing, and so it is necessary to decide the pool size of the tests in advance. When the pool size is not fit for the number of the defective samples, the estimation performance decreases. In order to solve this problem, the proposed method control the pool size adaptively based on the expected information gain of the next test, which is calculated from the l0-norm of the estimated sample vector. Experimental results indicate that the proposed method outperforms the conventional method by adapting the pool size to the unknown number of defective samples. |
