Method Detail

getLikelyhoods

double[] getLikelyhoods()

Get the likelyhoods values, ex. 0.011806375442739082

Returns:

The likelyhood values

getLikelyhoodFormulae

String[] getLikelyhoodFormulae()

For each likelyhood, get the formula ex. gL_cA_Yes / gL * ((gL_cA_Yes_fE_temp_is_Cool + alpha)/(gL_cA_Yes_fE_temp + ( gL_fE_temp_count * alpha )) * (gL_cA_Yes_fE_humidity_is_High + alpha)/(gL_cA_Yes_fE_humidity + ( gL_fE_humidity_count * alpha )) * (gL_cA_Yes_fE_outlook_is_Overcast + alpha)/(gL_cA_Yes_fE_outlook + ( gL_fE_outlook_count * alpha )) * (gL_cA_Yes_fE_wind_is_Strong + alpha)/(gL_cA_Yes_fE_wind + ( gL_fE_wind_count * alpha )) * 1 )

Returns:

The likelyhood formulae

getLikelyhoodExpressions

String[] getLikelyhoodExpressions()

For each likelyhood, get the expression ex. 9 / 14 * ((3 + 1.0 )/(9 + ( 3 * 1.0 )) * (3 + 1.0 )/(9 + ( 2 * 1.0 )) * (4 + 1.0 )/(9 + ( 3 * 1.0 )) * (3 + 1.0 )/(9 + ( 2 * 1.0 )) * 1 )

Returns:

The likelyhood algebraic expression
