In this study, we introduce a machine learning framework for medical imaging that combines the current pattern recognition approach ("radiomics") with Deep Learning (DL). We apply the framework in cancer bioimaging for prognosis of locoregional recurrence in head and neck squamous cell carcinoma (N=298) from Computed Tomography (CT) and Positron Emission Tomography (PET) imaging. The DL architecture is composed of two parallel cascades of Convolutional Neural Network (CNN) layers merging in a softmax classification layer. The network is first pretrained on head and neck tumor stage diagnosis, then fine-tuned on the prognostic task by internal transfer learning. In parallel, radiomics features (e.g., shape of the tumor mass, texture and pixels intensity statistics) are derived by predefined feature extractors on the PET-CT pairs. We first compare and then mix deep learning and radiomics features into a unifying classification pipeline (RADLER), where model selection and evaluation are based on a data analysis plan developed in the MAQC initiative for reproducible biomarkers. On the multimodal PET-CT cancer dataset, the mixed deep learning/radiomics approach is more accurate than using only one feature type, or image mode. Further, RADLER significantly improves over published results on the same data.
## Pretrained models
We share the weights of the models, as described in the manuscript. See folder [pretrained_weights](pretrained_weights).
## Setup
git clone
conda env create -f env.yml -n radler
conda activate radler
### Additional dependencies
#### MLPY
`mlpy` package is required for some operations included in the DAP procedure.
The `mlpy` package available on PyPI is outdated and not working on OSX platforms.
These are the steps to follow:
Let `<ANACONDA>` be your anaconda path (e.g., `/home/user/anaconda3`).
Adjust these environmental variables:
export CPATH=<ANACONDA>/envs/<ENV>/include:${CPATH}
and then install `mlpy` from GitLab:
pip install git+
