PyTorch package for KL-CPD algorithm for change point and anomaly detection in time series

Unofficial PyTorch implementation of KL-CPD

KL-CPD is an algorithm for change point and anomaly detection in time series.

More information can be found in the 2019 paper Kernel Change-point Detection with Auxiliary Deep Generative Models.

Usage

from klcpd import KL_CPD

dim, seq_length = 1, 100
ts = np.random.randn(seq_length,dim)
device = torch.device('cuda')
model = KL_CPD(dim).to(device)
model.fit(ts)
preds = model.predict(ts)
print(preds)

Installation

pip install git+https://github.com/HolyBayes/klcpd
