Business Cases

  • Face identification method based on a small number of data - algorithm development

    Face recognition by deep learning often requires large amounts of labeled training data, which can be very costly. To overcome this problem, we have developed a method for face identification with a small number of samples in this work.

    This method pre-trains a deep network based on existing labeled data, and then transfers the feature extraction part obtained from the pre-training to the deep network for the data given the label of the person to be recognized. We have confirmed that this method can achieve a high discrimination rate even with a small amount of data.

    Because training deep networks is very time consuming, multiple GPU instances were launched on AWS to evaluate discrimination accuracy for multiple network structures in parallel.

  • Estimating environmental conditions using metagenomic Data - R&D

    We developed a method for estimating environmental conditions using information on microbial communities obtained from metagenomic data acquired using next-generation sequencers.

    In this work, we create regression models (Lasso regression and support vector regression) to estimate environmental conditions based on the abundance of each microorganism.

    In addition, to forecast future microbiota, we created regression models that estimates species abundance of the following month based on data from a given month.

    We used Python for the above work.
