Applied deep learning techniques leveraging Azure machine learning to develop a classifier for detecting lung fibrosis from medical X-ray images based on the visual patterns in the images and the associated static features such as age, gender, smoking habit, family history (known cases of genetic diseases or conditions), medical history (past surgeries, illnesses, or treatments) etc., using PyTorch to train and evaluate the model. Resulted in a 30% reduction in false negative rates, leading to… Show more Applied deep learning techniques leveraging Azure machine learning to develop a classifier for detecting lung fibrosis from medical X-ray images based on the visual patterns in the images and the associated static features such as age, gender, smoking habit, family history (known cases of genetic diseases or conditions), medical history (past surgeries, illnesses, or treatments) etc., using PyTorch to train and evaluate the model.
