I’m a PhD student focusing on the application of machine learning to electron microscopy. This mainly means GPU-accelerated neural network training with TensorFlow. So far, I have written papers on

  • Improving electron micrograph signal-to-noise, especially in low-dose micrographs: This is achieved using a large neural network based on Xception.
  • Electron micrograph restoration and compression: This features 14 autoencoders, 15 kernels and 14 multilayer perceptrons. These can all be used for image restoration and the autoencoders have been trained for compression ratios up to 64:1.
  • Neural networks that play with each other to reduce scanning transmission electron micrograph beam exposure and scan time: We are actively developing an experimental system.
  • Adaptive learning rate clipping (ALRC) to limit backpropagated losses: ALRC complements existing learning algorithms to improve training stability, accelerate convergence and lower errors.
  • Deep learning supersampled (DLSS) scanning transmission electron microscopy: This increases spatiotemporal resolution and decreases electron dose without scan system modification.
