“…The decision tree classication model increases the information gain (IG) of a given classication (c, in this case simply "no-hit" or "hit") by decreasing the entropy (H) of a given set (S) which was calculated using eqn (1) using the probability of nding a specic class (p(c)). Information gain is the difference in entropy for the full set (S) and the sum of the entropies for all subsets (t) created by all splits (A) as shown in eqn (2…”

“…Tandem mass spectrometry (MS/MS) is a powerful analytical tool that is extensively used for the characterization of complex mixtures in many elds, such as proteomics, petroleomics, and drug discovery. [1][2][3][4] Currently, the most commonly used MS/MS technique to obtain structural information for ionized and isolated mixture components is collision-activated dissociation (CAD). 5,6 In these experiments, the analyte ions are accelerated and allowed to collide with an inert gas, such as helium.…”

“…Therefore, it is reasonable to expect that UHR‐MS can be used to identify characteristic chemical compositions that compose crude oil precipitates. Indeed, there have been studies devoted to understanding the chemical compositions of crude oil precipitates . For an example, Klein et al .…”

“…The concept of DBE numbers is widely used in the research topic of the high‐resolution mass spectrometric analysis of petroleum samples, and the chemical species with identical DBE numbers but different carbon numbers are usually assumed to be the molecules with the same aromatic core but different aliphatic chains in terms of overall chain length. Different from the iso‐abundance plots of typical fossil fuel samples, there are always less than four dots at each DBE row in Figure . This indicates that there are limited aliphatic side chains (less than 4) for these PAHs in the solid soot particulates.…”
