The first row represents the metrics measured after training on the whole dataset. “Reduced (ratio)” is the ratio of the size of the resulting reduced dataset to the size of the whole dataset. “Reduced SVs (ratio)” is the ratio of the number of SVs of the reduced dataset to that of the whole dataset.
