Quick Start

1. Prepare Your Dataset

Modify the load_data() function in run-multi-view-version.py to load your own dataset:

elif args.dataset_name == 'YourDataset':
    # Load each view into data_list
    data_list.append(mat['view1'])  # View 1: shape (n_samples, dim1)
    data_list.append(mat['view2'])  # View 2: shape (n_samples, dim2)
    data_list.append(mat['view3'])  # View 3: shape (n_samples, dim3) (optional)
    # ... add more views as needed
    label = np.squeeze(mat['label'].astype(np.uint8))

2. Configure Parameters

Key parameters in run-multi-view-version.py:

Parameter	Description	Default
--dataset_name	Name of your dataset	'Scene15'
--dataset_path	Path to dataset folder	'./datasets/'
--aligned_rate	Alignment ratio (1.0 = fully aligned, 0.5 = 50% PVP)	1.0
--train_time	Number of training runs for averaging	5

3. Run Training

python run-multi-view-version.py --dataset_name 'YourDataset' --aligned_rate 0.5 --train_time 5
