Different results

Dear Develoer, I have been interested in feature selection for a while. GINI index results in ITMO_FS are quite different between 0.3.3 and 0.3 versions when using the same data set. The values obtained according to the two versions are below

Feature- Gini values at 0.33 -- 0.30 'Q-1': 0.0171165 --- 0.017209 'Q-2': 0.0302192 --- 0.030236 'Q-3': 0.038750 --- 0.038718 'MeanQ': 0.0224271 --- 0.040471 ** 'MTI': 0.0418138 --- 0.071110 ** 'Prep': 0.071110 --- 0.018591 ** Humid': 0.002983 --- 0.047469 **** 'Temp': 0.051686 --- 0.024229 ** 'S': 0.035492569 --- 0.973375 **** 'T': 0.009388788 --- 0.015001 ** 'R': 0.032898059 --- 0.986235 ****

Is there a source explaining the difference between the two? Which Gini value should I take as the limit in the final version? How should I decide which feature to use or not in the next step? I would be glad if you could help Regards,

Dear Somacruz, GINI index results in ITMO_FS are quite different between versions 0.3.3 and 0.3 when using the same data set. Which Gini value should I take as the limit? Which feature(s) significant? How should I decide which feature to use or not in the AI model?

I would be glad if you could help Regards,
