In the sense that geometric planes and kernels of nonzero linear functions $\Bbb R^3\to\Bbb R$ coincide, hyperplanes in $n$-space are the appropriate generalization of geometric planes in $3$-space to arbitrary dimensions. Plot the maximum margin separating hyperplane within a two-class separable dataset using a Support Vector Machine classifier with linear kernel. In the case $n = 3$, this is usually how we define a plane orthogonal to the vector $(a_1,a_2,a_3)$, as the set of vectors $(x_1,x_2,x_3)$ satisfying is equal to $\mathbb R$), so the rank-nullity theorem tells us that the kernel of this linear map is an $(n-1)$-dimensional subspace of $\Bbb R^n$, i.e., a hyperplane in $\mathbb R^n$. Since $(a_1,\dots,a_n)$ is not the zero vector, the image of this linear map is a $1$-dimensional subspace of $\Bbb R$ (i.e. More explicitly, the hyperplane in the discussion is the kernel of the linear map $\Bbb R^n\to\Bbb R$ defined by Where $(a_1,\dots,a_n)$ is not the zero vector. In $\Bbb R^n$, an example hyperplane is defined by the equation (The number $1$ is often referred to as the "codimension" of the plane.) In the case $n = 3$, geometric planes may be thought of as the classic span of $2 = 3-1$ vectors in $\Bbb R^3$. We use the term hyperplane to speak of $(\dim V - 1)$-dimensional subspaces of a $(\dim V)$-dimensional vector space $V$. It is because the loss function used in the hyperparameter optimization step is the log probability of the parameters. To answer your question about the difference between a plane and a hyperplane, a plane and a hyperplane are the same thing in $\Bbb R^3$. Hyperparameter is selected in a way that maximizes the probability of the training set that is generated using the kernel as Bayesian prior. In $\Bbb R^3$, a hyperplane is a two-dimensional plane, and in $\Bbb R^2$, a hyperplane is a one-dimensional line. So, in the case of $\mathbb R^4$, you may think of a hyperplane as a rotated version of our three-dimensional space $\mathbb R^3$. In general, a hyperplane in $\Bbb R^n$ is an $(n-1)$-dimensional subspace of $\Bbb R^n$.
