Backpropagation is one of the most basic techniques in neural networks. Here, I have written some notes about it to provide an introduction and help beginners get started more easily. 1.Intuitively behind backpropagation Parameter updates in Neural Networks involve two parts: forward propagation and...
Back-propagation algorithmGeneralisation abilityIn recent years, back-propagation neural networks have become a popular tool for modelling environmental systems. However, as a result of the relative newness of the technique to this field, users appear to have limited knowledge about how ANNs operate ...
Gradient Descent is an optimization algorithm that is used to help train machine learning models. It makes use of the gradients computed by the backpropagation to update the value of weights and bias, always tending to minimize the loss function. This algorithm is used repetively in the trainnin...
The backpropagation algorithm can be directly applied to the computational graph of the unfolded network on the right, to compute the derivative of a total error (for example, the log-probability of generating the right sequence of outputs) with respect to all the states ht and all the ...
In the Root Path Cost algorithm, after a port receives a BPDU, the port extracts the value of the Root Path Cost field, and adds the obtained value and the path cost on the itself to obtain the root path cost. The path cost on the port includes only directly-connected path costs. The...
Gradient descent is one of the most fundamental and widely used optimization algorithms in machine learning and deep learning. Its primary role is to minimize a given function by iteratively moving towards the steepest descent direction, hence its name. This algorithm is essential for training machine...
Disabling backup policy for a service stops all periodic data backups happening as a result of propagation of this backup policy to the partitions of the service. Disabling backup policy for a partition stops all periodic data backup happening due to the backup policy at the partition. Wh...
a subset of the input having the same shape as the patch), passing input through a activation function, max pooling, softmaxing, loss calculation, etc. In order to work through back propagation, you need to first be aware of all functional stages that are a part of forward propagation. ...

Feature attribution methods, like Partial Dependence Plot (PDP) or Gradient-based Class Activation Map, highlight important features by perturbing the inputs or using backpropagation54. Recent approaches explain...
