• Title: Comparison of semi-supervised learning methods for High Content Screening quality control
• Authors: Umar Masud and Ethan Cohen and Ihab Bendidi and Guillaume Bollot and Auguste Genovesio
• Abstract summary: High-content screening (HCS) offers to quantify complex cellular phenotypes from images at high throughput. This process can be obstructed by image aberrations such as out-of-focus image blur, fluorophore saturation, debris, a high level of noise, unexpected auto-fluorescence or empty images. We evaluate deep learning options that do not require extensive image annotations to provide a straightforward and easy to use semi-supervised learning solution.

• Abstract: Progress in automated microscopy and quantitative image analysis has promoted high-content screening (HCS) as an efficient drug discovery and research tool. While HCS offers to quantify complex cellular phenotypes from images at high throughput, this process can be obstructed by image aberrations such as out-of-focus image blur, fluorophore saturation, debris, a high level of noise, unexpected auto-fluorescence or empty images. While this issue has received moderate attention in the literature, overlooking these artefacts can seriously hamper downstream image processing tasks and hinder detection of subtle phenotypes. It is therefore of primary concern, and a prerequisite, to use quality control in HCS. In this work, we evaluate deep learning options that do not require extensive image annotations to provide a straightforward and easy to use semi-supervised learning solution to this issue. Concretely, we compared the efficacy of recent self-supervised and transfer learning approaches to provide a base encoder to a high throughput artefact image detector. The results of this study suggest that transfer learning methods should be preferred for this task as they not only performed best here but present the advantage of not requiring sensitive hyperparameter settings nor extensive additional training.

  Fusarium Head Blight (FHB) is a serious fungal disease affecting wheat (including durum), barley, oats, other small cereal grains, and corn. Traditionally, trained agronomists and surveyors perform manual identification, a method that is labor-intensive, impractical, and challenging to scale. With the advancement of deep learning and Hyper-spectral Imaging (HSI) and Remote Sensing (RS) technologies, employing deep learning, particularly Conal Neural Networks (CNNs) has emerged as a promising solution.

  Poor-quality medical images may lead to misdiagnosis. We propose an explainable image quality assessment system and validate our idea on two different objectives. We apply a variety of techniques to measure the faithfulness of the saliency detectors. We show that NormGrad has significant gains over other saliency detectors by reaching a repeated Pointing Game score of 0.853 for Object-CXR and 0.611 for LVOT datasets.

  Cross-Domain Consistency Learning (CDCL) is a self-supervised approach that is able to learn in the presence of batch effects. CDCL enforces the learning of biological similarities while disregarding undesirable batch-specific signals. These features are organised according to their morphological changes and are more useful for downstream tasks.
