Figure 1. A diagram of the neural network we’ll use for our example. The idea in backpropagation with gradient descent is to consider the entire network as a multivariate function that provides ...

Here we show that there is a gradient of acetylation of histone H4 ... Thus, the Sas2p and Sir2p function in concert to regulate transcription in yeast, by acetylating and deacetylating H4 ...
