Enhancing Reference-based Sketch Colorization via Separating Reference Representations
Reference-based sketch colorization methods have garnered significant attention for the potential application in animation and digital illustration production. However, most existing methods are trained with image triplets of sketch, reference, and ground truth that are semantically and spatially similar, while real-world references and sketches often exhibit substantial misalignment. This mismatch in data distribution between training and inference leads to overfitting, consequently resulting …

Multi-Object Sketch Animation with Grouping and Motion Trajectory Priors
We introduce GroupSketch, a novel method for vector sketch animation that effectively handles multi-object interactions and complex motions. Existing approaches struggle with these scenarios, either being limited to single-object cases or suffering from temporal inconsistency and poor generalization. To address these limitations, our method adopts a two-stage pipeline comprising Motion Initialization and Motion Refinement. In the first stage, the input sketch is interactively divided into seman…

Iterative Methods for Computing the Moore-Penrose Pseudoinverse of Quaternion Matrices, with Applications
We develop iterative methods to compute the Moore-Penrose pseudoinverse of quaternion matrices directly in $\mathbb{H}$. We introduce a damped Newton-Schulz (NS) iteration, proving its convergence under spectral scaling $X_0=αA^H$ with $α\in(0,2/\|A\|_2^2)$. We derive higher-order hyperpower NS schemes with optimized factorizations. Beyond NS, we propose a randomized sketch-and-project method (RSP-Q) and a conjugate gradient on normal equations (CGNE-Q). Numerically, spectrally-scal…

Peeling metric spaces of strict negative type
We describe a unified and computationally tractable framework for finding outliers in, and maximum-diversity subsets of, finite metric spaces of strict negative type. Examples of such spaces include finite subsets of Euclidean space and finite subsets of a sphere without antipodal points. The latter accounts for state-of-the-art text embeddings, and we apply our framework in this context to sketch a hallucination mitigation strategy and separately to a class of path diversity optimization probl…

Error estimating coding (EEC) is a standard technique for estimating the number of bit errors during packet transmission over wireless networks. In this paper, we propose OddEEC, a novel EEC scheme. OddEEC is a nontrivial adaptation of a data sketching technique named Odd Sketch to EEC, addressing new challenges therein by its bit sampling technique and maximum likelihood estimator. Our experiments show that OddEEC overall achieves comparable estimation accuracy as competing schemes such as gEE…

PSketch: A Priority-Aware Sketch Architecture for Real-Time Flow Monitoring via eBPF
Sketch-based monitoring in SDN often suffers from tightly coupled pipeline and memory constraints, limiting algorithmic flexibility and reducing accuracy. We propose PSketch, the first in-kernel priority-aware sketching framework implemented with eBPF. It ensures lossless tracking of high-priority flows via a hash-based table and approximates top-k elephant flows using a sketch pipe. PSketch supports both TCP and UDP and enables in-kernel retransmission tracking with minimal overhead. Unlike SD…

SDGraph: Multi-Level Sketch Representation Learning by Sparse-Dense Graph Architecture
Freehand sketches exhibit unique sparsity and abstraction, necessitating learning pipelines distinct from those designed for images. For sketch learning methods, the central objective is to fully exploit the effective information embedded in sketches. However, there is limited research on what constitutes effective sketch information, which in turn constrains the performance of existing approaches. To tackle this issue, we first proposed the Multi-Level Sketch Representation Scheme to systemati…

This chapter starts with a sketch of how we got to "generative AI" (GenAI) and a brief summary of the various impacts it had so far. It then discusses some of the opportunities of GenAI, followed by the challenges and dangers, including dystopian outcomes resulting from using uncontrolled machine learning and our failures to understand the results. It concludes with some suggestions for how to control GenAI and address its dangers.

Non-IID data and partial participation induce client drift and inconsistent local optima in federated learning, causing unstable convergence and accuracy loss. We present FedSSG, a stochastic sampling-guided, history-aware drift alignment method. FedSSG maintains a per-client drift memory that accumulates local model differences as a lightweight sketch of historical gradients; crucially, it gates both the memory update and the local alignment term by a smooth function of the observed/expected p…

A High Performance GPU CountSketch Implementation and Its Application to Multisketching and Least Squares Problems
Random sketching is a dimensionality reduction technique that approximately preserves norms and singular values up to some $O(1)$ distortion factor with high probability. The most popular sketches in literature are the Gaussian sketch and the subsampled randomized Hadamard transform, while the CountSketch has lower complexity. Combining two sketches, known as multisketching, offers an inexpensive means of quickly reducing the dimension of a matrix by combining a CountSketch and Gaussian sketch.…

Here’s the lightning sketch of Paul’s Treatise Against Efficiency that I’ve never written:
1. Efficiency is asymptotically inefficient: as costs approach zero, the cost of further reducing them approaches infinity.
2. Efficiency prioritizes the measurable over the difficult-to-measure.
3. Efficiency prioritizes what those in power see (or imagine) over on-the-ground reality.
4. Following from 2 and 3, efficiency reduces the amount and quality of information flowing into a human system.
5. Efficiency foments institutional inflexibility.
6. By removing slack, efficiency causes small failures to cascade more readily and increases the risk of catastrophic failure.
7. Following rom 4, 5, and 6, efficiency trades small costs for massive risks: from failures, from missed opportunities, and from inability to adjust.
8. Efficiency, when pushed, strangles the emergent phenomena that in the long term create all new things of value.
9. Thus, although it can be a by-product of evolution, efficiency as a goal in itself strangles evolution.
10. Efficiency as a goal strangles joy.

A result from folklore, which we sketch in the appendix, shows that lax double functors are equivalent to functors with codomain their former domain. We use this result to ch…
