Web22 apr. 2024 · In general, we can maximize the mutual information between visual features x k and attributes a k by training the NCE-based MIE as follows: (9) I ( x k; a k) ≥ I w ( N C E) ( x k; a k). In addition to NCE being used to formulate the bound of mutual information, the MIE based on Jensen–Shannon Divergence (JSD) may also offer favorable trade-offs.
