Is Synthetic Image Useful for Transfer Learning? An Investigation into Data Generation, Volume, and Utilization

no code implementations28 Mar 2024 Yuhang Li, Xin Dong, Chen Chen, Jingtao Li, Yuxin Wen, Michael Spranger, Lingjuan Lyu

Synthetic image data generation represents a promising avenue for training deep learning models, particularly in the realm of transfer learning, where obtaining real images within a specific domain can be prohibitively expensive due to privacy and intellectual property considerations.

Assessing SATNet's Ability to Solve the Symbol Grounding Problem

no code implementations NeurIPS 2020 Oscar Chang, Lampros Flokas, Hod Lipson, Michael Spranger

We propose an MNIST based test as an easy instance of the symbol grounding problem that can serve as a sanity check for differentiable symbolic solvers in general.

MA-Dreamer: Coordination and communication through shared imagination

no code implementations10 Apr 2022 Kenzo Lobos-Tsunekawa, Akshay Srinivasan, Michael Spranger

Multi-agent RL is rendered difficult due to the non-stationary nature of environment perceived by individual agents.

Expert Human-Level Driving in Gran Turismo Sport Using Deep Reinforcement Learning with Image-based Representation

no code implementations11 Nov 2021 Ryuji Imamura, Takuma Seno, Kenta Kawamoto, Michael Spranger

We demonstrate that the proposed method performs expert human-level vehicle control under high-speed driving scenarios even with game screen images as high-dimensional inputs.

The Emergence of Abstract and Episodic Neurons in Episodic Meta-RL

no code implementations ICLR Workshop Learning_to_Learn 2021 Badr AlKhamissi, Muhammad ElNokrashy, Michael Spranger

In this work, we analyze the reinstatement mechanism introduced by Ritter et al. (2018) to reveal two classes of neurons that emerge in the agent's working memory (an epLSTM cell) when trained using episodic meta-RL on an episodic variant of the Harlow visual fixation task.

Logic Tensor Networks

1 code implementation25 Dec 2020 Samy Badreddine, Artur d'Avila Garcez, Luciano Serafini, Michael Spranger

In this paper, we present Logic Tensor Networks (LTN), a neurosymbolic formalism and computational model that supports learning and reasoning through the introduction of a many-valued, end-to-end differentiable first-order logic called Real Logic as a representation language for deep learning.
