Breast Tissue: Dataset with electrical impedance measurements of freshly excised tissue samples from the breast. 12. Daphnet Freezing of Gait: This dataset contains the annotated readings of 3 acceleration sensors at the hip and leg of Parkinson's disease patients that experience freezing of gait (FoG) during walking tasks.
13. Demospongiae: Marine sponges of the Demospongiae class classification domain. 14. Dermatology: Aim for this dataset is to determine the type of Eryhemato-Squamous Disease. 15. Echocardiogram: Data for classifying if patients will survive for at least one year after a heart attack 16. Ecoli: This data contains protein localization sites 17. EEG Database: This data arises from a large study to examine EEG correlates of genetic predisposition to alcoholism. It contains measurements from 64 electrodes placed on the scalp sampled at 256 Hz 18. Fertility: 100 volunteers provide a semen sample analyzed according to the WHO 2010 criteria. Sperm concentration are related to socio-demographic data, environmental factors, health status, and life habits 19.

SPECT Heart: Data on cardiac Single Proton Emission Computed Tomography (SPECT) images. Each patient classified into two categories: normal and abnormal. 34. SPECTF Heart: Data on cardiac Single Proton Emission Computed Tomography (SPECT) images. Each patient classified into two categories: normal and abnormal. 35. Statlog (Heart): This dataset is a heart disease database similar to a database already present in the repository (Heart Disease databases) but in a slightly different form 36.
