Python implementation of GRAIL
Project description
GRAIL
A Python implementation of GRAIL, a generic framework to learn compact time series representations.
Installation
Installation using pip:
pip install -m grailts
Usage
from GRAIL.Representation import GRAIL
from GRAIL.TimeSeries import TimeSeries
from GRAIL.kNN import kNN
TRAIN, train_labels = TimeSeries.load("ECG200_TRAIN", "UCR")
TEST, test_labels = TimeSeries.load("ECG200_TEST", "UCR")
representation = GRAIL(kernel="SINK", d = 100, gamma = 5)
repTRAIN, repTEST = representation.get_rep_train_test(TRAIN, TEST, exact=True)
neighbors, _, _ = kNN(repTRAIN, repTRAIN, method="ED", k=5, representation=None,
pq_method='opq')
print(neighbors)
