| Abstract: |
We demonstrate the use of deep learning methods to detect Kuiper Belt Objects (KBOs) in wide-field imaging data sets. Synthetic KBOs were added to time series observations. Those observations were divided into sub-image pairs to create a
two-channel training set. Convolutional neural networks were applied to extract useful features from the sub-image pairs and predict the existence of KBOs within the training set pairs. ImageNet classification architectures were effective at predicting the existence of a KBO within a sub-image pair. Our deep learning approaches effectively detect moving sources down to a signal-to-noise ratio of 5 per image in self-validating tests. Our goal is to apply this deep learning-based detection method to arbitrary time-series observations. |
