How Tesla approaches collision detection with novel methods. -
We discuss Sony AI's accomplishment of creating a novel AI agent that can beat professional racers in Gran Turismo. Some topics include:
- The crafting of rewards to make the agent behave nicely
- What is QR-SAC?
- How to deal with "rare" experiences in the replay buffer

Todays paper: Can Neural Nets Learn the Same Model Twice? Investigating Reproducibility
Relationship between model performance and reproducibilityWhich models are robust and reproducibleHow they calculate the various scores
and Double Descent from the Decision Boundary Perspective (https://arxiv.org/pdf/2203.08124.pdf)
Summary:
A discussion of reproducibility and double descent through visualizations of decision boundaries.

Todays paper: VICReg (https://arxiv.org/abs/2105.04906)
The VICReg architecture (Figure 1)Sensitivity to hyperparameters (Table 7)Top 5 metric usefulness
Summary of the paper
VICReg prevents representation collapse using a mixture of variance, invariance and covariance when calculating the loss. It does not require negative samples and achieves great performance on downstream tasks.

Summary of the paper
A multimodal SSL algorithm that predicts latent representation of different types of input.Highlights of discussion
What are the motivations of SSL and multimodalHow does the student teacher learning work?What are similarities and differences between ViT, BYOL, and Reinforcement Learning algorithms. -
This is the first episode of Argmax! We talk about our motivations for doing a podcast, and what we hope listeners will get out of it.
Todays paper: Reward is Enough
Summary of the paper
The authors present the Reward is Enough hypothesis: Intelligence, and its associated abilities, can be understood as subserving the maximisation of reward by an agent acting in its environment.Highlights of discussion
High level overview of Reinforcement LearningHow evolution can be encoded as a reward maximization problemWhat is the one reward signal we are trying to optimize?
