Christos Faloutsos (2007): Less is More: Compact Matrix Decomposition for Large Sparse Graphs.
SDM'07 Best Research Paper, Errata: Figure 5:ApprMultiplication algorithm is updated by adding line 8 and 12, which only keeps the matching columns in C\_d (line 8) and scaling factor for those columns is 1 (line 12: this is redundant in the implementation since the scaling factor is 1 but I specify out there for clarification purpose). Thank Sebastian K{\"o}hler, Ces Bertino and Jeffrey T. Johns for spotting that.

Christos Faloutsos (2005): Streaming pattern discovery in multiple time-series. VLDB Endowment.
Errata: 1) On the top of left column of P6, Algorithm TrackW requires a 3 step to orthogonalize $\vec{w}\_i, 1\le i\le k$ by fixing $\vec{w}\_1$, i.e., to apply Gram Schimdt orthogonalization with initial vector $\vec{w}\_1$ (keep the principal direction unchanged). 2) Lemma 4.1 the last term \|\vec{y}\_t\| should be squared, i.e., \|\vec{y}\_t\|^2.
