DeepGlioma#

The DeepGlioma model is a topic classification model trained on a scATAC-seq dataset of human gliomas obtained from Wang et al., 2019 (Cancer discovery). The dataset comprises 6 patient samples, 4 IDH–wild-type GBMs, 2 IDH-mutant grade II astrocytomas, and 2 IDH-mutant oligodendrogliomas.

Using pycisTopic, binarized topics per region were extracted for 24 target topics, where topics 8/21 and topics 20/25 represent patient-specific and patient-mixed MES-like states, while topics 14/18/19 represent an OPC/NPC-like state.

The model is a CNN multiclass classifier that uses the deeptopic_cnn() architecture.

Details of the data and the model can be found in the original publication.
