As an AI language model, I don't have enough context to understand the full meaning of this code. However, I can provide some explanation of what the code might be doing.
It looks like this is a line of code in a Python class method. The "self" keyword refers to an instance of the class. The code appears to be calculating the output of a neural network node using the sigmoid function.
The "@" symbol is the matrix multiplication operator in Python. It multiplies the matrix "x" by the matrix "self.v". The result is then subtracted by the value of "self.gama" and passed through the sigmoid function.
Overall, this line of code is likely a part of a larger neural network implementation for performing some kind of classification or prediction task.
