Optimal Analysis of Subset-Selection Based L_p Low Rank Approximation

Chen Dan, Hong Wang, Hongyang Zhang +2

We study the low rank approximation problem of any given matrix $A$ over $R^{n \times m}$ and $C^{n \times m}$ in entry-wise $ℓ_{p}$ loss, that is, finding a rank-…

Partition of a Subset into Two Directed Cycles with Partial Degrees

Hong Wang

Let $D = (V, A)$ be a directed graph of order $n \geq 6$ . Let $W$ be a subset of $V$ with $∣ W ∣ \geq 6$ . Suppose that every vertex of $W$ has degree at least $(3 n - 3) /2$ in $D$ . Then for…
