\mathrm{Score}=\alpha(\mathcal{H}(x_i^{\mathcal{U}}))-\frac1\alpha(\mathcal{MI}(x_i^{\mathcal{U}},\mathcal{T}))

$\mathcal{H(x_i^{\mathcal{U}})}$

\mathcal{H}(x_i^{\mathcal{U}})=-\sum_{q=0}^Q\sum_{c=0}^c p(y_i=c\mid x_i^{\mathcal{U}})\log(p(y_i=c\mid x_i^{\mathcal{U}}))

$\mathcal{MI}(x_i^{\mathcal{U}},\mathcal{T})$

\mathcal{MI}=\sum_{x_i^{\mathcal{T}}} P(x_i^{\mathcal{U}},x_i^{\mathcal{T}})\log(\frac{P(x_i^{\mathcal{T}},x_j^{\mathcal{U}})}{P(x_i^{\mathcal{T}})P(x_j^{\mathcal{U}})})

Liver and Liver Tumor Segmentation

Kaggle homepage | Homepage

The liver is a common site of primary (i.e. originating in the liver like hepatocellular carcinoma, HCC) or secondary (i.e. spreading to the liver like colorectal cancer) tumor development. Due to their heterogeneous and diffusive shape, automatic segmentation of tumor lesions is very challenging. Until now, only interactive methods achieved acceptable results segmenting liver lesions.

130 CT scans, resized to 256x256 and converted to PNG for segmentation of the liver as well as tumor lesions.
