SpletIt turns out that the more dimensions you have, the less meaningful the concept of distance becomes. Too many dimensions describing the data and almost all items in the database may seem about the same distance from one another. That is the curse of dimensionality. Spletdesirable for removing the curse of dimensionality 1 (COD). The need to choose ˙parameter is also critical as the kernel choice is actually a regularization choice and scaling …

SpletThis is because SVMs can perform well even when the number of features is much larger than the number of data points, which is known as the "curse of dimensionality." SVMs can also handle non-linearly separable data by using a kernel function, which maps the data into a higher-dimensional space where it becomes linearly separable.
