Link Propagation: A Fast Semi-supervised Learning Algorithm for Link Prediction
Hisashi Kashima,Tsuyoshi Kato,Yoshihiro Yamanishi,Masashi Sugiyama,Koji Tsuda +4 more
- 01 Dec 2009
TL;DR: This work proposes Link Propagation as a new semi-supervised learning method for link prediction problems, where the task is to predict unknown parts of the network structure by using auxiliary information such as node similarities.

Multi-Task Learning via Conic Programming
Tsuyoshi Kato,Hisashi Kashima,Masashi Sugiyama,Kiyoshi Asai +3 more
- 03 Dec 2007
TL;DR: This paper proposes a novel MTL algorithm that makes use of a task network, which describes the relation structure among tasks and control the relatedness of the tasks locally, so all pairs of related tasks are guaranteed to have similar solutions.
Segmental HOG: new descriptor for glomerulus detection in kidney microscopy image
Tsuyoshi Kato,Tsuyoshi Kato,Raissa Relator,Hayliang Ngouv,Yoshihiro Hirohashi,Osamu Takaki,Tetsuhiro Kakimoto,Kinya Okada +7 more
TL;DR: In this article, a new descriptor referred to as Segmental HOG was developed to perform a comprehensive detection of hundreds of glomeruli in images of whole kidney sections, which possesses flexible blocks that can be adaptively fitted to input images in order to acquire robustness for the detection of the glomerulus.

TL;DR: An extended version of the off-subspace noise-reduction (de-noising) method to incorporate heterogeneous network data such as sequence similarity or protein-protein interactions into a single framework to improve prediction of human cell cancer dru responses from microarray data is found.
New Descriptor for Glomerulus Detection in Kidney Microscopy Image.
Tsuyoshi Kato,Raissa Relator,Hayliang Ngouv,Yoshihiro Hirohashi,Tetsuhiro Kakimoto,Kinya Okada +5 more
TL;DR: A new descriptor referred to as Segmental HOG was developed to perform a comprehensive detection of hundreds of glomeruli in images of whole kidney sections and it is expected to be useful in pathological evaluation.
