Rubin大数据时代分类任务的贝叶斯神经网络

Bayesian Neural Networks for classification tasks in the Rubin big data era

Anais Möller, Thibault de Boissière

摘要:

即将进行的调查,如维拉C。Rubin Observatory Legacy Survey of Space and Time(LSST)计划将在未来10年内,每晚探测到1000万个随时间变化的源。这些信息将以连续流的形式传输给经纪人,经纪人将使用机器学习算法为各种科学案例选择最有希望的事件。我们研究了贝叶斯神经网络(BNN)在这类分类任务中的优势和挑战。BNN被发现是准确的分类器,也提供了额外的信息:它们量化了分类的不确定性,可以利用这些不确定性来更有效地分析即将到来的数据雪崩。

英文摘要:

Upcoming surveys such as the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will detect up to 10 million time-varying sources in the sky every night for ten years. This information will be transmitted in a continuous stream to brokers that will select the most promising events for a variety of science cases using machine learning algorithms. We study the benefits and challenges of Bayesian Neural Networks (BNNs) for this type of classification tasks. BNNs are found to be accurate classifiers which also provide additional information: they quantify the classification uncertainty which can be harnessed to analyse this upcoming data avalanche more efficiently.
