First Session Adaptation: A Strong Replay-Free Baseline for Class-Incremental Learning

ICCV 2023poster

In Class-Incremental Learning (CIL) an image classification system is exposed to new classes in each learning session and must be updated incrementally. Methods approaching this problem have updated both the classification head and the feature extractor body at each session of CIL. In this work, we…

Scalable marked point processes for exchangeable and non-exchangeable event sequences

AISTATS 2023poster

We adopt the interpretability offered by a parametric, Hawkes-process-inspired conditional probability mass function for the marks and apply variational inference techniques to derive a general and scalable inferential framework for marked point processes. The framework can handle both exchangeable…

How Good Are Low-Rank Approximations in Gaussian Process Regression?

AAAI 2022technical

We provide guarantees for approximate Gaussian Process (GP) regression resulting from two common low-rank kernel approximations: based on random Fourier features, and based on truncating the kernel's Mercer expansion. In particular, we bound the Kullback–Leibler divergence between an exact GP and on…
