Why does the batch size control the number of examples in the batch in deep learning?
In the realm of deep learning, particularly when employing convolutional neural networks (CNNs) within the TensorFlow framework, the concept of batch size is fundamental. The batch size parameter controls the number of training examples utilized in one forward and backward pass during the training process. This parameter is pivotal for several reasons, including computational efficiency,

Can the activation function be only implemented by a step function (resulting with either 0 or 1)?
The assertion that the activation function in neural networks can only be implemented by a step function, which results in outputs of either 0 or 1, is a common misconception. While step functions, such as the Heaviside step function, were among the earliest activation functions used in neural networks, modern deep learning frameworks, including those

Can loss be considered as a measure of how wrong the model is?
The concept of "loss" in the context of deep learning is indeed a measure of how wrong a model is. This concept is fundamental to understanding how neural networks are trained and optimized. Let's consider the details to provide a comprehensive understanding. Understanding Loss in Deep Learning In the realm of deep learning, a model
Is it better to feed the dataset for neural network training in full rather than in batches?
When training neural networks, the decision of whether to feed the dataset in full or in batches is a important one with significant implications on the efficiency and effectiveness of the training process. This decision is grounded in the understanding of the trade-offs between computational efficiency, memory usage, convergence speed, and generalization capabilities. Full Dataset

How does the layerwise learning technique address the vanishing gradient problem in QNNs?
The vanishing gradient problem is a significant challenge in training deep neural networks, including Quantum Neural Networks (QNNs). This issue arises when gradients used for updating network parameters diminish exponentially as they are backpropagated through the layers, leading to minimal updates in earlier layers and hindering effective learning. The layerwise learning technique has been proposed
What is the barren plateau problem in the context of QNNs, and how does it affect the training process?
The barren plateau problem is a significant challenge encountered in the training of quantum neural networks (QNNs), which is particularly relevant in the context of TensorFlow Quantum and other quantum machine learning frameworks. This issue manifests as an exponential decay in the gradient of the cost function with respect to the parameters of the quantum
