Comma values - best predictive model suggestion

Bambo

Hello, I would like to know what is the best predictive operator to solve my problem.

 

 

So my main goal is to find the best predictive operator which could handle comma values (Input 1, Input 2, Input 3) and values in "Input 4" column (YES/NO) and predict values in "Output" column. I already tried Optimize Parameters(Evolutionary) with operators like [SVM kernel types: (radial, anova, epachenikov etc), Random Forest, Neural Net, Decision Tree] to find optimal values, but the average accuracy of prediction was low.

 

I would really like to know if someone could suggest some predictive operator which could produce the best accuracy for this kind of problem.

NOTE: The values in columns "Input 1, Input 2, Input 3" after adding up always equals 100% in every row if this helps.

Thanks very much in advance.

Hi @Bambo,

 

You could try new 'Auto Model' feature to find the best predictive model for given data set.

Hi @Bambo

 

For me, it would matter if the output column represents an arbitrary integer value or a categorical value (and in the latter case, how many unique categories you can have). If it's categorical, you could possibly use any non-linear algorithm like decision tree / RF / GBT. If it's numerical, then regression models would fit, but most likely you'll have to transform boolean column then.

 

Generally speaking, you still have to experiment with different models and compare results.
