Last night's ADSN conference dinner at Thai Pothong was fantastic! Just look at the cocktail I had order, never seen anything like it! It had mango, pineapple, and even sticky rice in it. Definitely would go back to this restaurant the next time I'm in Sydney. #ThaiPothong #Sydney #FancyCocktail

Enjoying the Australian Data Science Network (ADSN) Conference at the University of Sydney. Quite a few interesting talks on AI, LLMs, machine learning, and data science. It's been a great opportunity to meet and network with the folks in this area. #datascience #AI #machinelearning #LLMs #ADSN

Off to Sydney to attend the Australian Data Science Networking Conference for a few days. Hopefully the weather will be a bit less gloomy in Sydney.

The final instalment (for now) of my blog series on predicting exoplanet orbital obliquities is now live (www.astrobrett.com/obliquity_ML...)! Here I use a simplified binary random forest classifier model to predict obliquity classes. #DataScience #MachineLearning #Exoplanets #RandomForest

Part 4 of my blog series on predicting exoplanet orbital obliquities is now live (www.astrobrett.com/obliquity_ML...)! Here I use a random forest classifier model to predict obliquity classes. Stay tuned for the final installment of this series, coming soon! #DataScience #MachineLearning #Exoplanets

Rantings of a madman! The rest of the world should turn their backs on Trump and America. #madman #DonaldTrump

WTF! Sounds to me like Dump wants to forcefully annex Canada via economic warfare. I'm truly embarrassed right now that I'm an American and my heart goes out to Canada. As I'm living in Australia, I will boycott US products and try to buy Canadian products when I can. #Tarrifs #Canada #DonaldTrump

Part 3 of my blog series on predicting exoplanet orbital obliquities is now live (www.astrobrett.com/obliquity_ML...)! I improved the model with physically derived imputation & engineering new features. Stay tuned for Part 4 on a classifier approach. #DataScience #MachineLearning #Exoplanets

Over the past few months, I've been working on an exciting data science project using machine learning to explore exoplanets. I’ve documented my findings/methods in a series of blog posts on my website (www.astrobrett.com/data_science...), so check it out! #DataScience #MachineLearning #Exoplanets

Does Meta enable scammers on their platforms? I've noticed tons of scammer 'sponsored' content on Facebook, illegally using trademark brands (e.g., JBHIFI) to scam people. I've reported these, but according to Facebook, there's nothing wrong with these ads. It's one of many reasons I'm leaving Meta.

I plan on using this platform for data science and astronomy related content, including projects I'm working on. But for my first post, I thought I would share these photos I took of an impressive double rainbow 🌈 from this afternoon after a heavy thunderstorm. #rainbow #thunderstorm #Toowoomba
