In the inference phase, we generate a test case for each focal method. To do so, we use a beam search [27] as a decoding method. We leverage beam search to select multiple candidates for an input sequence at each time-step. Algorithm 1 presents the pseudocode of the beam search algori...

This structure was energy minimized in vacuo by 10,000 steps of steep-descent algorithm and served as a building block for preparation of mGSDMA3Nterm oligomers. Construction of mGSDMA3Nterm oligomers Membrane-inserted ring-shaped oligomers were prepared by rotating the above prepared mGSDMA3Nterm ...
Machine learning can generally be summarized as: starting from the data, selecting a certain model, updating the parameter values of the model through an optimization algorithm, so that the indicator performance of the task becomes better (learning objective), and finally learning a "good"...
(v.3.1.4). Briefly, each 1080-frame EER movie was divided into 40 subgroups, and beam-induced motion was corrected using a MotionCor2-like algorithm implemented in RELION. Exposure-weighted micrographs were then imported into cryoSPARC for CTF (contrast transfer function) estimation by patch CTF...
