HMLasso™* Factor analysis technology

Unravel factors with complex interrelationships, even from among fragmented data.


  • Accurately build regression models using sparse modeling, even with large volumes of missing data.
  • Contributes to increasing yield and productivity at factories and plants with sampling inspections.
  • Lasso with High Missing Rate

Applications



  • Identify factors behind decreased yield in semiconductor plants
  • Can also be applied in factor analysis of failures and abnormalities in infrastructure and office equipment

Benchmarks, strengths, and track record



  • Results of joint research with Inter-University Research Institute Corporation, Research Organization of Information and Systems, Institute of Statistical Mathematics
  • Estimation error reduced by approximately 41% compared to cutting-edge algorithm “CoCoLasso”
