No deep learning and only machine learning

Notebooks · 30 Sep 2020, 11:45 · 10

If we use only machine learning such as Light GBM model on the image pixel values read as array, we can reach <1 RMSE values. While this implementation is inferior to deep learning models, it could have some usage in resource constrained environment where availability of GPU is an issue.

Sample code here:

Thank you, I am wondering about the training time, since you're not using any gpu and the dimensiality is so high?

Training time is not too high about 20-30 mins for entire pipeline

7839 is just the size of low quality images. And 3136 is 56*56

I tried it, with multiples variation, and I noticed that it fits the training data very quikly, but overfit so hard, I tried diffrent methods, and they don't seem to work good, but the technique defentley can get less than 1 rmse

Try attempting to use extracted image embeddings (new to Zindi and this piqued my interest, an example being the following https://www.kaggle.com/s/2543927)
