基于机器学习的OGLE-IV瞬态过程实时检测

Real-time detection of transients in OGLE-IV with application of machine learning

Jakub Klencki, Łukasz Wyrzykowski

摘要:

目前在大多数调查中的瞬态检测的瓶颈是从检测到的候选人中拒绝大量工件的问题。我们提出了一个三阶段的分层机器学习系统的自动伪影过滤差分成像,自组织映射的基础上。该分类器在OGLE-IV瞬态检测系统上进行测试时,可接受约97%的真实瞬态,同时消除高达约97.5%的伪影。

英文摘要:

The current bottleneck of transient detection in most surveys is the problem of rejecting numerous artifacts from detected candidates. We present a triple-stage hierarchical machine learning system for automated artifact filtering in difference imaging, based on self-organizing maps. The classifier, when tested on the OGLE-IV Transient Detection System, accepts ~ 97 % of real transients while removing up to ~ 97.5 % of artifacts.
