Solve the following python programming problem given the following code:
# Define linear regression class

class linear_regression(nn.Module):
    
    # Constructor
    def __init__(self, input_size, output_size):
        super(linear_regression, self).__init__()
        self.linear = nn.Linear(input_size, output_size)
        
    # Prediction
    def forward(self, x):
        yhat = self.linear(x)
        return yhat
Given the above code, generate some markdown instructions for it.
