PhD Seminar • Artificial Intelligence — Gradient-based Filter Design for the Dual-tree Wavelet Transform

Daniel Recoskie, PhD candidate
David R. Cheriton School of Computer Science

The wavelet transform has seen success when incorporated into neural network architectures, such as in wavelet scattering networks. More recently, it has been shown that the dual-tree complex wavelet transform can provide better representations than the standard transform.

Seminar • Algorithms and Complexity — Drawing Planar Graphs with Few Geometric Primitives: Algorithms and Evaluation

Philipp Kindermann, Postdoctoral Fellow
David R. Cheriton School of Computer Science

The visual complexity of a graph drawing is defined as the number of geometric objects needed to represent all its edges. In particular, one object may represent multiple edges, e.g., one needs only one line segment to draw two collinear incident edges.
