“…This is consistent with general thermodynamic considerations, as vibrational and rotational degrees of freedom give rise to heat capacity, 60,61 and heat capacity is proportional to a factor with dependence on zpve. 62 Fish weight is strongly predicted (r 2 = 0.98) by the square of the length2 property multiplied by factors related to width and the ratio of height to length3, which differs from the basic intuition that weight scales linearly with volume, which in a rst-order approximation is the simple product of length, width, and height. The feature for predicting the compressive strength of concrete includes roughly half of the variables available in the original dataset, which suggests that several ingredients in the concrete formulation (water, cement, aggregates) are signicantly more important for predicting compressive strength than others (y ash, furnace slag, and superplasticizers) which are not present in the engineered feature.…”
