Which model do you prefer, assuming both have zero training error?
Model structure (for both models):
$$
h_{\boldsymbol{\theta}}(x)=\theta_0+\theta_1 x+\theta_2 x^2+\theta_3 x^3+\theta_4 x^4+\theta_5 x^5+\theta_6 x^6+\theta_7 x^7+\theta_8 x^8
$$
Model parameters:
$$
\boldsymbol{\theta}=\left[\begin{array}{lllllll}
\theta_0, & \theta_1, & \theta_2, & \theta_3, & \theta_4, & \theta_5, & \theta_6,
&\theta_7, & \theta_8
\end{array}\right]^T
$$
$\text { A. } \quad \boldsymbol{\theta}_A=[-190.0,-135.0,310.0,45.0,-62.0,90.0,-82.0,-40.0,29.0]^T$
$\text { B. } \quad \boldsymbol{\theta}_B=\left[\begin{array}{lllllllll}
25.5, & -6.4, & -0.8, & 0.0, & 6.6, & -4.4, & 0.2, & -2.9, & 0.1
\end{array}\right]^T$
The violet line reprents model A and green line represents model B.
(Please enter 0 for A and 1 for B)
