Coeus is a machine-learning project that uses NASA’s Kepler data to classify planetary candidates and false positives. It combines astronomical data analysis, predictive modelling, and visualisation to explore patterns in exoplanet detection.

~ COEUS IS OUT!!
Coeus is a machine-learning application that explores how data science can help distinguish potential exoplanets from false-positive detections in NASA’s Kepler mission catalogue. Using ten astronomical and stellar features, including orbital period, transit duration, transit depth, planetary radius, and host-star properties. Coeus analyses patterns in Kepler Objects of Interest (KOIs) and predicts whether each object is classified as a planetary candidate or a false positive.

Built using Python and logistic regression, the project combines data preprocessing, predictive modelling, classification-threshold experiments, performance evaluation, and scientific visualisation. It investigates how measurable transit characteristics contribute to classification while examining

Coeus — Kepler Exoplanet Classification

  • Explored and cleaned NASA’s Kepler Objects of Interest (KOI) dataset.
  • Analysed 6,816 observations containing planetary candidates and false positives.
  • Selected 10 numerical features, including orbital period, transit duration, transit depth, planetary radius, and stellar properties.
  • Built a logistic regression model to classify planetary candidates and false positives.
  • Evaluated model performance using accuracy, precision, recall, F1-score, and a confusion matrix.
  • Investigated the effects of classification thresholds on candidate detection.
  • Visualised transit depth against orbital period to examine patterns and overlap between the two classes.
  • Identified limitations caused by class imbalance and overlapping feature distributions.
  • Worked on interpreting predictions cautiously, recognising that classification does not confirm the existence of an exoplanet.
