Shadows Aren't So Dangerous After All: A Fast and Robust Defense Against Shadow-Based Adversarial Attacks

1 code implementation18 Aug 2022 Andrew Wang, Wyatt Mayor, Ryan Smith, Gopal Nookula, Gregory Ditzler

Robust classification is essential in tasks like autonomous vehicle sign recognition, where the downsides of misclassification can be grave.

AdaWCT: Adaptive Whitening and Coloring Style Injection

no code implementations1 Aug 2022 Antoine Dufour, Yohan Poirier-Ginter, Alexandre Lessard, Ryan Smith, Michael Lockyer, Jean-Francois Lalonde

We show, through experiments on the StarGANv2 architecture, that this generalization, albeit conceptually simple, results in significant improvements in the quality of the generated images.

Overparameterization Improves StyleGAN Inversion

no code implementations12 May 2022 Yohan Poirier-Ginter, Alexandre Lessard, Ryan Smith, Jean-François Lalonde

We show that this allows us to obtain near-perfect image reconstruction without the need for encoders nor for altering the latent space after training.

Language Models in the Loop: Incorporating Prompting into Weak Supervision

no code implementations4 May 2022 Ryan Smith, Jason A. Fries, Braden Hancock, Stephen H. Bach

Our experimental evaluation shows that prompting large language models within a weak supervision framework can provide significant gains in accuracy.

Reward Maximisation through Discrete Active Inference

no code implementations17 Sep 2020 Lancelot Da Costa, Noor Sajid, Thomas Parr, Karl Friston, Ryan Smith

Precisely, we show the conditions under which active inference produces the optimal solution to the Bellman equation--a formulation that underlies several approaches to model-based reinforcement learning and control.

In-Session Personalization for Talent Search

no code implementations18 Sep 2018 Sahin Cem Geyik, Vijay Dialani, Meng Meng, Ryan Smith

Previous efforts in recommendation of candidates for talent search followed the general pattern of receiving an initial search criteria and generating a set of candidates utilizing a pre-trained model.
