  • Machine learning on sets of samples where individual labels are unknown - R&D

    We developed a machine learning algorithm to estimate whether a certain number of samples of a given type are present in a large number of samples.

    The underlying technique is Multiple Instance Learning (MIL), which is a learning method used when labels for a set of samples are given as supervised data. In general supervised learning, each sample needs to be labelled in advance, but it can be applied when individual samples do not have labels.

    Standard MIL assumes that the presence or absence of a certain type of sample in the set is used as a label. Even if the available label is whether or not a certain number of samples of a certain species in a set are present, it can be treated as standard MIL with special pre-processing.

  • Phase recovery algorithms for coherent x-ray analysis - implementation and acceleration

    We implemented and accelerated the phase recovery algorithm for diffraction analysis using coherent X-rays produced at SPring-8 and other beamlines.

    Several algorithms, based on holography and other technologies specified by the customer, were implemented.

    In terms of algorithm acceleration, the phase recovery algorithm used by the customer was parallelized on CPUs and GPUs. As a result, the analysis process, which used to take several hours, can now be processed in a few minutes.

    [Introduction]
    I have conducted research on algebraic topological generalizations of the h-principle, a key technique in differential topology. While my primary expertise lies in algebraic topology, particularly in homology, I am also proficient in analytical methods and have explored areas such as symplectic and contact geometry. The strength of mathematics lies in its high universality, leading to technological innovations through its applications in unexpected fields. I offer the best mathematical approaches for research and development situations where breakthroughs in technical difficulties or new discoveries are required.
