One-hot encoding contributed to a decrease of 0.157 units of logarithmic loss. Kaggle competition winners are decided in slightest of margins and an offset of 0.05 could be the difference between being in the top 75% and top 25% on the leaderboard. Now that we have established one-h...
If the browser type is Firefox then with one-hot encoding x_firefox would be set to 1 and x_safari would be set to 0. The activated weight for the Firefox type would be its predetermined weight of 0.8 multiplied by the encoded value of 1. So x_firefox would equal 0.8. The activated...
One-hot encoding can be memory intensive, so use this technique when the number of categories can be very large. Order does not matter for categorical functions. One-hot encoders are used when: For categorical features, when label order is not important. ...
