, and then predict the type of training sample. Perceptron is an error-driven (error-driven) learning algorithm. If the perceptron is correct, the algorithm continues to process the next sample. If the perceptron is wrong, the algorithm updates the weights and re-predicts. The update rules for weights are as follows: For each training sample, an increase in the parameter value of each explanatory variable α (Dj-yj (t)) XJ,I,
output of 1.
RBF Network Training:
The goal of the training is to find the final weights of the two tiers CJ, DJ and WJ.
The training process is divided into two steps: The first step is unsupervised learning, training to determine the weights between the input layer and the hidden layer CJ, Dj; the second step is supervised learning to determine the WJ of the weights between the hidden layer and the outpu

Description during college, it is often necessary to rent a classroom. Large to the Department to organize activities, small to study group discussion, all need to apply to the school to borrow the classroom. The classroom size function is different, borrows the classroom person's identity to be different, borrows the classroom The procedure also is dissimilar.In the face of the vast amount of information rented classrooms, we naturally want to program to solve this problem.We need to deal with
If the slope of the line is 0 or there is no slope, there is a $NC (m,3) +MC (n,3) $ scheme. If the slope of the line is not 0, just consider the case where the slope is positive, and the final answer is multiplied by 2. To enumerate the coordinates of two points, set $t=\min (n,m) $, there are:\[\begin{eqnarray*}Ans=\sum_{i=1}^n\sum_{j=1}^m (n-i) (M-j) (\GCD (I,J)-1) \ \=\SUM_{D=1}^T\SUM_{I=1}^N\SUM_{J=1}^M[\GCD (I,J) =d] (n-i) (M-j) (\GCD (I,J)-1) \ \=\SUM_{D=1}^T\SUM_{I=1}^{\LFLOOR\FRAC{N}{D}

Using the
Returns and Jumps
Like Java, there are 3 jump statements in Kotlin return break continue break and Continue tags
We can give an alias to any expression, Kotlin call this a label.
Take an example of the previous for Loop statement
Doctorq@for (index in array.indices) {
println (index)
}
I've added a label to this for loop, with a suffix of @
doctorq@ for (i-1..100) {
doctorq2@ for (J-in 1..100) {
if (i > J) break@doctorq2
if (i = =) Break@doc
I am about to take a test of Java. I have studied the examples of producers and consumers in the book. The book is only a program for a single consumer and a single producer. On the basis of this, I changed it to multiple producers and multiple consumers, unfortunately, the deadlock occurred, and I was puzzled. After studying the entire morning, the background finally found the cause through discussions with the teacher ------- notify () is to wake up a thread at random.
If the producer produces
mouse move to suspend the prompt document like eclipse
Alt + f12 started through the terminal
Press ctrl + space twice to import the prompts in other namespaces
The SQL prompt is also displayed.
Ctrl + q quick notes
Use ctrl + B to view declarative Information
Rename the shortcut key shift + f6
Ctrl + o quick rewrite method, ctrl + I quick implementation Interface
The shortcut key ctrl + shift + space can prompt the code segment.

Each neuron receives the stimulus Yi and then the weighted accumulation (weighted Wji ) is completed after the XJ is produced, and then stimulated by the activation function of yJ , The next layer of neurons to which it is connected is passed, and, in turn, results are eventually output.We will then analyz
