Fig. 2From: Multi-target drug repositioning by bipartite block-wise sparse multi-task learningThe calculated W of different methods for Data2.0 (1 st row), Data2.1 (2 nd row), Data2.2 (3 rd row) and Data2.3 (4th row). Column (a): Ground truth W; (b): W connectivity mapping analysis test; (c): W ℓ1 regularization; (d): ℓ2,1 regularization; (e): BBSS-MTL with λ3=0. BBSS-MTL performs best among all the methods in all simulated data set for learning the WBack to article page
