Pseudocode Yes Algorithm 1: Fed MSGL Input: Multi-view dataset with n view X1, X2, , Xn, Hyperparameter λ1,λ2 and λ3. Ouput: Global model G and the cluster indicator matrix F. Initialize Ck, Uk 1: while converge do Local node: do calculation among nodes parallel 2: for i = 1 to itermax do 3: if i = 1 then replace Ck with G; 4: else update Ck by Eq.(17); 5: update Uk by Eq.(20); 6: end if 7: end for send Ck and Uk to server; Central Server: 8: for i = 1 to itermax do update G by Eq.(24); 9: update F by solving Eq.(25); 10: end for send G to nodes; 11: end while
Open Source Code No The paper does not contain any explicit statements about releasing source code, nor does it provide any links to a code repository.
Open Datasets Yes We conducted experiments on five multi-view datasets and four have differing feature dimensions. Sonar1,BBC Sport2,ORL3 ,Handwritten4 and Caltech101-75. The statistics of the five datasets are summarized in Table.2. ... 1http://archive.ics.uci.edu/dataset/151/connectionist+bench +sonar+mines+vs+rocks 2http://mlg.ucd.ie/datasets/bbc.html 3https://www.cl.cam.ac.uk/research/dtg/attarchive/facedat abase.html 4https://archive.ics.uci.edu/dataset/72/multiple+features 5http://www.vision.caltech.edu/archive.html
Dataset Splits No The paper lists the datasets used and their statistics (sample, view, feature dimension) in Table 2, but it does not specify any training, testing, or validation splits for these datasets.
Hardware Specification Yes All experiments are conducted on the i9-14900KF and 32.0GB RAM, MATLAB R2021b.
Software Dependencies Yes All experiments are conducted on the i9-14900KF and 32.0GB RAM, MATLAB R2021b.
Experiment Setup Yes Parameters setting For the compared methods mentioned above, we use the parameters recommended by the authors. For the proposed method Fed MSGL, we select λ1, λ2 and λ3 from the range {1e 3, 1e 2, , 1e2, 1e3}. The value of β is chosen from the range {1e 2, 1e 1, 1, 10, 100}. After that, we choose specific hyperparameter combinations based on model performance variations.
