The Automatic Diatom Identification and Classification (ADIAC) project was a pilot study concerning automatic identification of diatoms (unicellular algae) on the basis of images. A dataset containing the prices and other attributes of almost 54,000 diamonds.

The variables are as follows:
df
: data.frame
with the following variables:
class
: Corresponding class level of “Ardiac” curves (with 37 number of classes)
sample
:Factor variable. In UCR, the first 390 values (sample=train
) are used for training sample and the rest of 391 (sample=test
) for testing.
x
: fdata
class object with with n=781 curves (per row) in a sequence length of 176 discretization points (per column).
The dataset originally had 37 classes. This built-in data sets one class as the positive class (class 1) and all others are set to the negative class (class 0) to form a highly imbalanced dataset.
