. Because like other mechanical computers of that era, the machine was just an exaggerated odometer. Similar to the machines of Charles Babbage (Charles Babbage, British mathematician, inventor, and mechanical engineer) nearly 200 years later, it is difficult to achieve a large number of rotary tables at the same time from a mechanical point of view when large-scale movements occur.Leibniz initially built a wooden prototype that was planned to handle only 3 to 4 digits of arithmetic. But during

is decremented by 1 and becomes 5.8. Minus 1 after Operationm=6r=$ ((4+m--))The value of the row 2,m is 6, and 4 is the addition operation, the value is 10, and then assigned to R. Next, the value of M is reduced by 1. Operation Result: R=10,m=5.If you want to do the arithmetic operation of the unit on the variable itself, you can use (()) to enclose it, which is similar to the syntax of the C language.As shown below:1. Specify the operation((i=168))The value of the set variable i is

In the summary of Bayesian individualized sequencing (BPR) algorithm, we discuss the principle of Bayesian personalized sequencing (Bayesian personalized Ranking, hereinafter referred to as BPR), and we will use BPR to make a simple recommendation from the practical point of view. Since the existing mainstream open source class library has no BPR, and it is relatively simple, so with TensorFlow to implement a simple BPR algorithm, let us begin.1. BPR Algorithm ReviewBPR algorithm is a sort algor
