New Artificial Intelligence Tool May Speed Up Drug Discovery Using Images New Artificial Intelligence Tool May Speed Up Drug Discovery Using Images Japanese researchers are using artificial intelligence (AI) to gain insights from cryo-electron microscopy. Artificial intelligence (AI) machine learning is transforming pharmaceutical drug discovery. Advances in deep learning, a subset of machine learning, is enabling researchers to identify patterns in fields where there are large amounts of complex data, such as imaging. In a recent study published in Nature Machine Intelligence, researchers in Japan created an AI deep neural network to extract information on protein dynamics from images captured using cryo-electron microscopy (cryo-EM).
