In the context of Deep Learning, what does 'invariance' refer to?
Ability to ignore variations in input data
Why is it important for a system to be highly selective in distinguishing between different objects?
To improve generalization and robustness
What distinguishes reinforcement learning from supervised and unsupervised learning?
The network is driven by a reward signal but is not told how to maximize the reward.
How did AlphaGo Zero differ from the original AlphaGo in terms of learning approach?
AlphaGo Zero used reinforcement learning only, while AlphaGo used a mixture of supervised and reinforcement learning.
What is the biological significance of reinforcement learning in animals?
There are parallels between reinforcement learning algorithms and reward processing involving dopamine in the human brain.
What differentiates Go from chess as mentioned in the text?
Go is considered one of the world's most complex games with more possible moves than chess.
How does reinforcement learning differ from simply repeating past successful strategies?
Reinforcement learning requires the network to engage in trial and error for discovering new reward-generating strategies.
What was the outcome of AlphaGo Zero playing against previous versions of AlphaGo?
After 40 days, AlphaGo Zero was able to beat all existing versions of AlphaGo.
What type of input did the machine receive while playing Atari Breakout?
Sensory input similar to what would be seen on the screen during gameplay.
In which type of learning does the network not receive explicit feedback but learns to detect patterns in data?
Unsupervised Learning
What role does dopamine play in reinforcement learning as discussed in the text?
Dopamine drives reward processing within neural networks similar to reinforcement learning algorithms.
