A backpropagation algorithm, or backward propagation of errors, is analgorithmthat's used to help trainneural networkmodels. The algorithm adjusts the network's weights to minimize any gaps -- referred to as errors -- between predicted outputs and the actual target output. Weights are adjustable...
Backpropagation is a training algorithm used for a multilayer neural networks, it allows for efficient computation of the gradient. The backpropagation algorithm can be divided into several steps: 1) Forward propagation of training data through the network in order to generate output. 2) Use target...

is the partial derivative of the loss for the weight –it measures how sensitive the loss function is to changes in the weight; this gradient tells us the direction to adjust to decrease the loss 2.1. Backpropagation The backpropagation algorithm involves main phases: the forward and backward ...
Whether it’s right or wrong, a “backpropagation” algorithm adjusts the parameters—that is, the formulas’ coefficients—in each cell of the stack that made that prediction. The goal of the adjustments is to make the correct prediction more probable. “It does this for right answers, too...
The Backpropagation Algorithm * Now we're finally ready to tackle the problem of training multilayer neural networks (instead of just single neurons). So what's the idea behind backpropagation? We don't know what the hidden units ought to be doing, but what we can do is compute how fast...
Miners use the consensus algorithm to solve the encrypted hash equation and verify the new block. The first miner that completes the verification of the new block adds the new block to the blockchain and broadcasts to other miners that the mining is complete, and then reaps the cryptocurrency...
In the context of simulation and embedded computing, it is about approximating real-world values with a digital representation that introduces limits on the precision and range of a value. Quantization introduces various sources of error in your algorithm, such as rounding errors, underflow or ...
Generally, among multiple paths, there is one path providing better signal quality than the other paths. The receive end uses a certain algorithm to allocate different weights to receiving paths. For example, the receive end allocates the highest weight to the path providing the best signal ...
