Raw light curve data from exoplanet transits is too complex to naively apply traditional outlier detection methods. We propose an architecture which estimates a latent representation of both the main transit and residual deviations with a pair of variational autoencoders. We show, using two fabricated datasets, that our latent representations of anomalous transit residuals are significantly more amenable to outlier detection than raw data or the latent representation of a traditional…

Searching for exoplanets using artificial intelligence
TLDR
The study indicates that machine learning will facilitate the characterization of exoplanets in future analysis of large astronomy data sets by allowing data to be evaluated from different time series after interpolation without compromising performance.
Unsupervised Anomaly Detection Using Variational Auto-Encoder based Feature Extraction
TLDR
Variational Auto-Encoder (VAE) is applied to extract valuable features for the unsupervised anomaly detection tasks and results show that features obtained by VAE can make unsuper supervised anomaly detection approaches perform better.
Variational Autoencoder based Anomaly Detection using Reconstruction Probability
TLDR
The reconstruction probability has a theoretical background making it a more principled and objective anomaly score than the reconstruction error, which is used by autoencoder and principal components based anomaly detection methods.
Fast and Easy Exoplanet Transit Modelling in Python
TLDR
The aim of PyTransit is to facilitate the analysis of photometric time series of exoplanet transits consisting of hundreds of thousands of datapoints, and of multi-passband transit light curves from spectrophotometric observations, as a part of a researchers programming toolkit for building complex, problem-specific, analyses.
ENSEMBLE LEARNING METHOD FOR OUTLIER DETECTION AND ITS APPLICATION TO ASTRONOMICAL LIGHT CURVES
Outlier detection is necessary for automated data analysis, with specific applications spanning almost every domain from financial markets to epidemiology to fraud detection. We introduce a novel
Optimized transit detection algorithm to search for periodic transits of small planets
We present a new method to detect planetary transits from time-series photometry, the transit least squares (TLS) algorithm. TLS searches for transit-like features while taking the stellar limb
A Machine Learning Technique to Identify Transit Shaped Signals
We describe a new metric that uses machine learning to determine if a periodic signal found in a photometric time series appears to be shaped like the signature of a transiting exoplanet. This metric
Systematic serendipity: a test of unsupervised machine learning as a method for anomaly detection
Advances in astronomy are often driven by serendipitous discoveries. As survey astronomy continues to grow, the size and complexity of astronomical databases will increase, and the ability of
Identifying Exoplanets with Deep Learning: A Five Planet Resonant Chain around Kepler-80 and an Eighth Planet around Kepler-90
TLDR
A method for classifying potential planet signals using deep learning, a class of machine learning algorithms that have recently become state-of-the-art in a wide variety of tasks, is presented and two new planets are identified with high confidence by this model.
Properties of starspots on CoRoT-2
Context. As a planet eclipses its parent star, a dark spot on the surface of the star may be occulted, causing a detectable variation in the light curve. Aims. We study these light curve variations
