• Abstract summary: Infertility is a global health problem, and an increasing number of couples are seeking medical assistance to achieve reproduction. Previous sperm assessment studies with deep learning have used datasets comprising only sperm heads. We constructed a video dataset for sperm assessment whose videos include sperm head as well as neck and tail, and its labels were annotated with soft-label.

• Abstract: Infertility is a global health problem, and an increasing number of couples are seeking medical assistance to achieve reproduction, at least half of which are caused by men. The success rate of assisted reproductive technologies depends on sperm assessment, in which experts determine whether sperm can be used for reproduction based on morphology and motility of sperm. Previous sperm assessment studies with deep learning have used datasets comprising images that include only sperm heads, which cannot consider motility and other morphologies of sperm. Furthermore, the labels of the dataset are one-hot, which provides insufficient support for experts, because assessment results are inconsistent between experts, and they have no absolute answer. Therefore, we constructed the video dataset for sperm assessment whose videos include sperm head as well as neck and tail, and its labels were annotated with soft-label. Furthermore, we proposed the sperm assessment framework and the neural network, RoSTFine, for sperm video recognition. Experimental results showed that RoSTFine could improve the sperm assessment performances compared to existing video recognition models and focus strongly on important sperm parts (i.e., head and neck).

  Global infertility rates are increasing, with 2.5% of all births being assisted by in vitro fertilisation (IVF) in 2022. The assessment of sperm DNA is traditionally done through chemical assays which render sperm cells ineligible for IVF. With the advent of state-of-the-art machine learning and its exceptional performance in many sectors, this work builds on these successes. Rendering a predictive model which preserves sperm integrity and allows for optimal selection of sperm for IVF.

  Bongard-HOI is a new visual reasoning benchmark that focuses on compositional learning of human-object interactions from natural images. It is inspired by two desirable characteristics from the classical Bongard problems (BPs): 1) few-shot concept learning, and 2) context-dependent reasoning. Bongard-HOI presents a substantial challenge to today's visual recognition models.
