25. Using Identity Mapping

Problem Statement

Which of the following Networks uses skip connections with all layers connected to each other using identity mapping? ResNet AlexNet Boltzman Machine DenseNet Which of the following is generally the best strategy while training a neural network? Start with a relatively high learning rate and gradually reduce it in each epoch Start with a relatively small learning rate and gradually increase it in each epoch Bigger the learning rate, the better. So keep a constant, very high learning rate Smaller the learning rate, the better. So keep a constant, very low learning rate We are most likely to find a global minima of an objective function if the objective function is: Only Convex Only Differentiable Neither Convex Nor Differentiable Both Convex and Differentiable Which of the below machine learning techniques can be used for dimensionality reduction of data? (i) Linear regression, (ii) t-Distributed Stochastic Neighbor Embedding (t-SNE), (iii) Principal Component Analysis, (iv) Decision Tr
