Summary

ivis is a dimensionality reduction technique that implements a Siamese Neural Network architecture trained using a novel triplet loss function. Results on simulated and real datasets demonstrate that ivis preserves global data structures in a low-dimensional space and adds new data points to existing embeddings using a parametric mapping function.

ivis is easily integrated into standard machine learning pipelines through a scikit-learn compatible API and scales well to out-of-memory datasets. Both supervised and unsupervised dimensionality reduction modes are supported.

Further information on the algorithm and its application to single cell datasets can be found in [@ivis_scirep]. Implementation of the ivis algorithm is available on GitHub.
