The theoretical maximum link setup rate can be reached only when the rank of the H matrix is n and each row vector or column vector is not closely related. This poses a great challenge to the antenna design of APs. In some tests, the link setup rate between the two ends of a Wi-Fi...
What if a 2 \times 2 matrix has only one eigenvalue? What is the dimension of an n by m matrix? If matrix a^2 = a, what is a? What is the rank of a matrix? If C is a 5x1 matrix and D is a 3x5 matrix, what are the dimensions of DC? What is ab^{-1} matrix? For...
aUsing the notions of rank, condition number, size and the SVD, we can analyse whether or not the matrix is singular, how many independent columns exist, what columns are dependent and to what degree. 使用等级、情况数字、大小和SVD的概念,我们可以分析是否矩阵是单一的,多少个独立专栏存在,什么专...
Using the matrix, it’s then easy to multiply severity times likelihood to get an impact score in the form of a number value. A risk that’s catastrophic and very likely would rank as a 25, whereas one that’s insignificant and very unlikely would rank as a one. It’s a simple and...
suggests that when fine-tuning an LLM for a downstream task, you don’t need the full-rank weight matrix. They proposed that you could preserve most of the learning capacity of the model while reducing the dimension of the downstream parameters. (This is why it makes sense to separate the...
