It is known that correlation-immune (CI) Boolean functions used in the framework of side-channel attacks need to have low Hamming weights. The supports of CI functions are (equivalently) simple orthogonal arrays when their elements are written as rows of an array. The minimum Hamming weight of...
The foundation of thewheremethod’s functionality lies in creating Boolean masks based on specified conditions. These masks are essentially arrays or series ofTrueandFalsevalues, representing whether each element satisfies the given condition. Given a DataFrame: import pandas as pd data = { 'Name':...
Step 3 - Apply AND logic The parentheses let you control the order of operation. We need to calculate the comparisons before we multiply the arrays. (B3:B12=D14)*(C3:C12=D15) returns {0;0;0;0;1;0;0;0;0;0}. Boolean values, when multiplied, return their numerical equivalents. TRUE...
neural nets have a couple of pages of weights in big arrays for all the sum of products etc. You can make them do idiotic simple stuff, like a boolean condition, and it will take several pages of weights, multiplications, lookup tables, and such to get the result. Its the old sledgeha...
When a block consists of only one expression, the curly brackets are optional, but for readability and maintainability, you should get into the habit of always using them, even when they're optional. Ready to jump into loops and ifs? Note that the examples in the following sections require ...
The function which decides whether an item in the original array should be included in the resulting array can contain any number of conditions – in fact, it’s a standard JavaScript function, so you can do pretty much whatever you want in it – just so long as you return a boolean TRU...
You can also use the size function to simply find how many values meet one of the conditions using(arr[np.where()]).sizefunction. For instance, to create a NumPy array calledarrwith values[5, 10, 15, 20, 25]and then filters the array based on a condition using boolean indexing. Spec...
The actions in our rules have even greater flexibility. An action is not restricted to returning a Boolean value. In fact, most actions will perform assignments and manipulate fields and properties in a workflow. In our first rule, we've used a rule action to assign an initial score of 0...
As shown in the screenshot below, the formulas produce the same result, so which one to use is a matter of your personal preference. For me, the formula with the Boolean logic is easier to read and build – it allows adding as many conditions as you want without nesting additional IF ...
