Adapting to Covariate Shift in Real-time by Encoding Trees with Motion Equations

no code implementations8 Apr 2024 Tham Yik Foong, Heng Zhang, Mao Po Yuan, Danilo Vasconcellos Vargas

In this paper, we demonstrated how a neural network integrated with Xenovert achieved better results in 4 out of 5 shifted datasets, saving the hurdle of retraining a machine learning model.

Synthetic Shifts to Initial Seed Vector Exposes the Brittle Nature of Latent-Based Diffusion Models

no code implementations24 Nov 2023 Mao Po-Yuan, Shashank Kotyan, Tham Yik Foong, Danilo Vasconcellos Vargas

To understand the impact of the initial seed vector on generated samples, we propose a reliability evaluation framework that evaluates the generated samples of a diffusion model when the initial seed vector is subjected to various synthetic shifts.

Generating Oscillation Activity with Echo State Network to Mimic the Behavior of a Simple Central Pattern Generator

no code implementations19 Jun 2023 Tham Yik Foong, Danilo Vasconcellos Vargas

However, we find that a reservoir that develops oscillatory activity without any external excitation can mimic the behaviour of a simple CPG in biological systems.

Dynamical Equations With Bottom-up Self-Organizing Properties Learn Accurate Dynamical Hierarchies Without Any Loss Function

no code implementations4 Feb 2023 Danilo Vasconcellos Vargas, Tham Yik Foong, Heng Zhang

The hurdle is that general patterns are difficult to define in terms of dynamical equations and designing a system that could learn by reordering itself is still to be seen.
