    1. The following figure presents a simple functional diagram of the neural network we will use throughout the article. The neural network is a sequence of linear (both convolutional A convolution calculates weighted sums of regions in the input. In neural networks, the learnable weights in convolutional layers are referred to as the kernel. For example Image credit to https://towardsdatascience.com/gentle-dive-into-math-behind-convolutional-neural-networks-79a07dd44cf9. See also Convolution arithmetic. and fully-connected A fully-connected layer computes output neurons as weighted sum of input neurons. In matrix form, it is a matrix that linearly transforms the input vector into the output vector. ), max-pooling, and ReLU First introduced by Nair and Hinton, ReLU calculates f(x)=max(0,x)f(x)=max(0,x)f(x)=max(0,x) for each entry in a vector input. Graphically, it is a hinge at the origin: Image credit to https://pytorch.org/docs/stable/nn.html#relu layers, culminating in a softmax Softmax function calculates S(yi)=eyiΣj=1NeyjS(y_i)=\frac{e^{y_i}}{\Sigma_{j=1}^{N} e^{y_j}}S(yi​)=Σj=1N​eyj​eyi​​ for each entry (yiy_iyi​) in a vector input (yyy).

    1. A neural network will predict your digit in the blue square above. Your image is 784 pixels (= 28 rows by 28 columns with black=1 and white=0). Those 784 features get fed into a 3 layer neural network; Input:784 - AvgPool:196 - Dense:100 - Softmax:10.

    1. Why interactive explanations? I find that I learn best when combining the language side of my brain (reading, formulas) with the visual side of my brain (illustrations, interaction). I want to learn not only by reading something or watching something, but by playing with it. I’m mostly focused on small, self-contained articles, but I’m also interested in interactive textbooks.

    1. You can find a list of applications using this gem in this repository: https://github.com/m-Peter/nested-form-examples . All the examples are implemented in before/after pairs. The before is using the accepts_nested_attributes_for, while the after uses this gem to achieve the same functionality.

    1. Source code at:

      This example appears to use client-side data, so it doesn't demonstrate server-side row models at all.

      How did they color the monthly breakdown cells?

              cellClassRules: {
                  'good-score': 'typeof x === "number" && x > 50000',
                  'bad-score': 'typeof x === "number" && x < 10000'

    3. secure tenure of office

      Teacher tenure (interestingly, here called "tenure of office") is still far from a settled matter. From the Phi Delta Kappan in 2018:

      "Originally enacted to protect against potential evils in state and local employment systems, such as nepotism, arbitrary dismissal, and political favoritism, tenure has become a common expectation of teacher employment. State teacher tenure laws are not a job guarantee but rather protection against arbitrary or politically motivated maltreatment. But is tenure on the way out?"
