CRanker for Peptide/Protein Identification

Develop new models to improve accuracy of peptide and protein identification using deep learning

Computational methods:

We first apply the deep learning model on feature extraction from peptide and protein data, and then use weighted SVM classifier to identify correct target.

Students:

• Chandra sekhar polavarapu (MS student)

Software Used:

• Python
• Tensorflow
• LibSVM

Grants:
