A is a real symmetric matrix, so we have many sets of $\big \{ \alpha _ { \mathrm { i } } \big \}$ that is orthogonal to each other. $\beta ^ { T } \cdot \beta =$ $\textstyle \sum _ { \mathrm { i } = 1 } ^ { \mathrm { n } } a _ { \mathrm { i } } b _ { \mathrm { i } } \geq 0$ , For every eigenvalue, the dimension of the subspace will be very high in the case of neural architecture search, so we assume that we can choose a set of $\big \{ \alpha _ { \mathrm { i } } \big \}$ orthogonal to each other from the subspace satisfying Pni+1j=ni $\sum _ { \mathrm { j = n _ { i } } } ^ { \mathrm { n _ { i + 1 } - 1 } } a _ { \mathrm { j } } b _ { \mathrm { j } } \geq 0$ in most cases $\mathrm { { \acute { n } _ { i } } }$ is the id of the first eigenvector w.r.t $\lambda _ { \mathrm { i } }$ ).
