A subspace is a subset that needs to be closed under addition and multiplication. That means if you take two members of the subspace and add them together, you'll still be in the subspace. And if you multiply a member of the subspace by a scalar, you'll still be in the subspace. If these two conditions aren't met, your set is not a subspace.Transcribed image text: a 7.

When the transformation between the test image and model images is2 Linear Transformations and Matrices A standard approach in algebra is to study collections of sets with a common structure and the maps between them which preserve that structure. In linear algebra this means vector spaces and the maps which behave nicely with respect to their defining structure, namely addition and scalar multiplication. A subspace is any set H in R n that has three properties: The zero vector is in H. For each u and v in H, the sum u + v is in H. For each u in H and each scalar c, the vector c u is in H. Another way of stating properties 2 and 3 is that H is closed under addition and scalar multiplication. Every Span is a SubspaceSources of subspaces: kernels and ranges of linear transformations.

Transfer learning is performed to train a model and extract the deep features from different output layers. p. Let q, X, Y and Z be defined as above. Since the exponential image of any linear subspace of Mp is totally geodesic, by restricting to the image of a three-dimensional subspace of Mp, we may assume dim M = 3.
