Questions & Answers

Q: How do adversarial algorithms manipulate learning algorithms?

Adversarial algorithms manipulate learning algorithms by introducing imperceptible noise or modifying visual information in order to force them to make incorrect decisions. This showcases the vulnerability of learning algorithms to adversarial attacks.

Q: What is the difference between the two noise types used in the adversarial techniques?

The first noise type adds imperceptible noise to a large portion of the video input, while the second noise type makes more visible modifications, such as adding a fake ball to a game. Both types effectively fool the learning algorithms but have different degrees of visibility.

Q: Are only DeepMind's algorithms affected by these adversarial techniques?

No, besides DeepMind's Deep Q-Learning, two other high-quality learning algorithms were also fooled by these techniques. This indicates the vulnerability of learning algorithms as a whole to adversarial attacks.

Q: What is the difference between the white box and black box formulations of adversarial attacks?

The white box formulation allows researchers to have access to the inner workings of the algorithm, while the black box formulation relies on knowledge of the game itself, training a separate system to identify weaknesses and exploit them. Both approaches contribute to breaking other systems.

Summary & Key Takeaways

• Google DeepMind achieved superhuman performance in Atari games using learning algorithms, but researchers are now focused on breaking these algorithms through fraudulent tampering.

• OpenAI has introduced two methods of adversarial attacks: one adds imperceptible noise to a video input, forcing the algorithm to choose a different action, while the other modifies visual information to coerce the algorithm into making incorrect decisions.

• These techniques can fool high-quality learning algorithms, including Deep Q-Learning, and highlight the need for robust algorithms that can withstand adversarial attacks.
