WebSep 26, 2024 · The hyperparameters you will tune are C and gamma. C controls the regularization strength. It is analogous to the C you tuned for logistic regression in Chapter 3, while gamma controls the kernel coefficient: Do not worry about this now as it is beyond the scope of this course. WebApr 9, 2024 · The Heat Capacity at Constant Pressure (C p)/ Heat capacity at Constant Volume(C v) The isentropic expansion factor is another name for heat capacity ratio that is also denoted for an ideal gas by γ (gamma). Therefore, the ratio between C p and C v is the specific heat ratio, γ. So, \[\gamma = \frac{C_{p}}{C_{v}}\]
