  • ACTIVE LEARNING IN MODEL TRAINING
    Publication number: 20240169253
    Abstract: Using a first dataset of labeled data, a model is trained by adjusting a feature extractor parameter, a classifier parameter, and a discriminator parameter of the model. Using the discriminator parameter and a parametric function of the feature extractor parameter, a plurality of samples of a dataset of unlabeled data is scored. A subset of the scored plurality of samples is selected for labeling. Responsive to receiving a label of each of the selected subset of the scored plurality of samples, the first dataset of labeled data is augmented with the selected subset of the scored plurality of samples and the label of each of the selected subset of the scored plurality of samples. Using the augmented dataset of labeled data, the model is retrained. The retraining comprises further adjusting the feature extractor parameter, the classifier parameter, and the discriminator parameter of the model.

  • Multiparallel three dimensional optical microscopy system
    Patent number: 6839469
    Abstract: Volume imaging is supported in an optical apparatus that simultaneously acquires multiple images from multiple focal planes in an image object. A plurality of image detectors is arranged with respect to an objective lense. A plurality of reflective devices are disposed between the objective lense and the plurality of detectors to divide the light travelling through the objective lense to the detectors into channels such that each channel is registered with a respective detector.

  • Sample holder for an imaging system
    Publication number: 20020131167
    Abstract: A sample holder for use with a system for imaging a sample is disclosed. The sample holder includes a stage contact member for contacting with a stage. A sample holding member holds the sample to be imaged by the system. One or more adjustment mechanisms can be used to adjusting the position of the sample holding member relative to the stage.
