When a model is trained on more features than samples (a phenomenon known as the curse of dimensionality), it may become overfitted, meaning that the patterns learnt are too specific to the dataset. Consequently, the model may not make reliable predictions on new input, especially from differen...

After the first hour, as a consequence of the reduced amount of HD on the surface, the air concentration of HD at 40ºC became lower than that of 25ºC and reached the threshold limit much faster, meaning that time to complete evaporation decreased with the increased in temperature. ...
[58], meaning Factor 1 was identified as an industrial source. Factor 2 had high loadings for both DBA and InP. DBA and InP are typical indicators of gasoline combustion in vehicles [19,38,59], therefore, Factor 2 was identified as gasoline emissions. Factor 3 was characterized by BkF ...
