I need new freelancer at low budget. I need a complete, end-to-end Python pipeline that accurately segments brain-tumor regions on the BraTS 2023 MRI dataset. The job covers everything from data loading and preprocessing through model training, validation, and inference. You’re free to choose the deep-learning framework you’re most productive with—PyTorch, TensorFlow, or Keras—as long as the final code is clean, reproducible, and clearly commented. a deep learning-based segmentation model using TransUNet, a hybrid CNN + Transformer-based U-Net model, to automatically segment brain tumors from MRI scans in the BraTS 2023 dataset.
