A Machine Learning Approach to Predicting Hacker News Post Popularity(gauzycode.com)

    This is such an interesting topic! I'd love to see how the ML model performs compared to human intuition.

    • datasciencepro 1 year ago | next

      From what I can tell, the model takes into consideration several features, including the timing, author, and topic, to make a prediction. Really smart!

      Very cool! What kind of model did you use, a regression or classification?

      • datasciencepro 1 year ago | next

        We utilized cross-validation and a grid search strategy for hyperparameter tuning. This was crucial in finding the best model, and it makes me optimistic that there is still room for improvement.

    We used a logistic regression model, but I'm curious to experiment with other types of models as well.

    • randomuser2 1 year ago | next

      A logistic regression could be a great starting point. I suppose using cross-validation and hyperparameter tuning would help improve its performance.

        That's a nice result! Do you think you could share your code and methodology in a GitHub repository or elsewhere?

        • originalauthor 1 year ago | next

          We definitely can, we'll make sure to share our project on GitHub in the coming days.

    I wonder if using a neural network instead could lead to better predictions. I'm curious what your training set looked like.

    • originalauthor 1 year ago | next

      Our dataset contained around 100,000 previous Hacker News posts, with 50 features engineered by the team. However, computational constraints prevented us from trying more complex models like neural networks.

    • randomuser3 1 year ago | prev | next

      100,000 data points is actually a pretty decent size, and 50 features sounds like a good number. I think the logistic regression may be strong enough to predict popularity.

  • opensourcefan 1 year ago | prev | next

    I appreciate the openness of discussing your methodology and approach. Looking forward to seeing your project on GitHub!

    Would a GAM (Generalized Additive Model) or a GBoost offer any advantages for this task as compared to a logistic regression?

    • datasciencepro 1 year ago | next

      Both GAM and GBoost can model complex relationships without explicitly assuming linearity. However, the simplicity of logistic regression would keep it interpretable and easy to understand. I think a comparative evaluation could be an interesting follow-up to this study.

    Do you plan to develop this approach further to include a scoring system like YCombinator's points system?

    • originalauthor 1 year ago | next

      We have discussed that idea, but no concrete decisions have been made yet. It's still an open area for exploration.
