1. What is gpio?
The full name of gpio is general-purpose Io ports, that is, general input and output ports.
In embedded systems, many simple external devices or Circuits need to be controlled. Some of these devices need to be controlled by the CPU, and some need the CPU to provide the input signal. In addition, as long as many devices or circuits require an on/off two shaped bodies, such as LED light and off. Traditional serial ports or parallel ports are complicated to control these devices. T

Calling interface for unified hardware2. Fixed the issue of GPI copyright 3. For a number of special requirementsIn the LED driver, we joined HAL to use the program does not need to care about the Linux driver and device files interactive way. To write a Linux driver th

deviceThe Perceptron is equivalent to a single layer of a neural network, consisting of a linear combination and an original binary threshold value:A single-layer perceptron that forms the Ann system:The perceptron computes a linear combination of these inputs with a real value vector, and outputs 1 if the result is greater than a certain threshold, otherwise the output ‐1.The Perceptron function can be written as: sign (w*x) can sometimes be added to the bias B, written as "W*x+b"Learning a pe

B. Run
Now that you have completed the steps to create the graphic, we go to the part of the graph that is being calculated.
Creates a numpy array, which will be filled in the upper placeholder.
To perform an operation on a graph: input x, Y, W1, W2 into the NumPy array, and a w1 array of losses (loss), W2 gradients, and numpy gradients.

convolutional neural networkconvolutional neural network is a kind of artificial neural network, which has become the research hotspot in the field of speech analysis and image recognition. Its weight-sharing network structure makes it more similar to the biological neural network, reduces the complexity of the network model and reduces the number of weights. This advantage is more obvious when the input of the network is multidimensional image, so t

2. Algorithm analysisBased on the above analysis, you learn that you need to create two arrays, create a collection of vertices, and a collection of edges to hold the weights of the points to each edge, then select the vertices of the smallest weighted edge pairs in the weights collection, and then continue the loop.
Create vertices in conjunction with Nnodein
o'clock, the linear model Y = * X is better fitting with the sample data.So when the number of items X = 6 o'clock, we can roughly estimate the total price y = 20 * 6 = 120Multivariate regression:A linear regression greater than an independent variable is called multivariate regression.The above example is just a self-variable, which is easier to handle, but if there are many independent variables, it is assumed that the arguments are M, [X1,X2,X3,X4.....XM].At this point we assume that the reg
