The UCB1 algorithm uses the following formula when determining which arm to pull in the Multi-Armed Bandit problem: 
  
 Which of the following describes best the role of the parameter y:

Accepted Answer

y trades off Exploration and Exploitation. Higher values of y increase exploration and decrease exploitation.

Answer

y is the Learning Rate. Higher values of y may result in faster convergence, but allow only smaller updates.

Answer

y is a Regularization parameter. Higher values of y can better deal with noise in the training examples, but may lead to a worse fit on the training data.
