OmniGraph: Rich Representation and Graph Kernel Learning
Table 1: Mean accuracy by sector for the majority class baseline, three benchmarks, and OmniGraph with two graph kernels. The cases where the sector mean is significantly better than the baseline are marked by *. OmniGraph is significantly better than all three benchmarks in all cases.
['GICS', 'Sector', 'Baseline', 'BOW', 'DepTree', 'SemTreeFWD', 'OmniGraph [ITALIC] WL', 'OmniGraph [ITALIC] NEW']
Both versions of OmniGraph significantly outperform the three benchmarks. The cells with asterisks represent a difference from the baseline that is statistically significant. OmniGraphWL beats the baseline with statistical significance in six sectors, and OmniGraphNEW in seven. Note that none of the benchmarks outperforms the baseline.
