写python代码，要求如下：用python表示：将LeNet-5改进为单类识别的神经网络，使用Python中的深度学习框架，如TensorFlow

Sure, I can definitely help you with that! To modify LeNet-5 for single-class recognition, you will need to make some changes to the final layer of the network. Specifically, you will need to replace the softmax output layer with a single neuron that uses a sigmoid activation function. This will allow the network to output a probability score between 0 and 1 for the single class that you are interested in recognizing.

As for the choice of deep learning framework, TensorFlow is certainly one popular option. Other frameworks such as PyTorch, Keras, or Caffe are also worth considering depending on your specific needs and preferences. Do you have any other questions or need further clarification on this topic?
