The majority of that species (Lady Bug) are generally considered useful insects.

In such situations, they can do a major crop damage. https://en.wikipedia.org/wiki/Coccinellidae

Quite interesting! Great to see something unique in the feed. Keep up the good work! 👍 \nOutlier detection and handling is a very crucial sept of ML. Do not miss it!

\n\n

You might find my notebook on advanced Outlier Handling helpful. It involves a lot of visualizations, analysis, and hard work I put in for days to make sure I am providing sound and fundamental concepts. A bit of support would be appreciated if you enjoy it or you could let me know in the comments if you have some suggestions or criticism for me! :)

I have recently also tried getting into Audio Processing and Classification for the competition Cornell Birdcall Identification. Do check out my extensive work on Audio feature extraction in my notebook.
