WebAn Example of How AdaBoost Works. Step 1: A weak classifier (e.g. a decision stump) is made on top of the training data based on the weighted samples. Here, the weights of each sample indicate how important it is to be correctly classified. Initially, for the first stump, we give all the samples equal weights. WebNov 26, 2024 · Advantages of Adagrad: No manual tuning of the learning rate required. Faster convergence More reliable One main disadvantage of Adagrad optimizer is that alpha (t) can become large as the number of iterations will increase and due to this will decrease at the larger rate.
