Reasons and methods to solve the problem of neural network output being 0
The output of the neural network may be 0 for the following reasons:
1. Neurons are inhibited: Neurons may be inhibited by other neurons, resulting in an output of 0 .
2. Input is 0: The input of the neuron may be 0, resulting in an output of 0.
3. Weight is 0: If the weight of the neuron is 0, then the output will be 0 no matter what the input is.
Some activation functions, such as sigmoid and tanh, when the input approaches negative infinity or positive infinity, the output will be close to 0.
5. Inactive neurons: If some neurons are not activated, their output will be 0.
It is recommended to analyze the cause according to the specific situation and take corresponding measures to adjust the neural network.
When the output of the neural network is 0, it can be adjusted through the following solutions.
What to do if some neural network outputs are 0
If some neural network outputs are 0, it will affect the accuracy of the entire network. Solutions include: redesign the network structure, add nonlinear activation functions, or use regularization techniques.
Check the weight: Make sure the weight of the neuron is not 0, otherwise you can try to retrain the network or change the weight initialization method.
Replace the activation function: If the output of the activation function is 0, you can try to use other activation functions, such as ReLU or LeakyReLU. These activation functions will not have an output of 0.
Activate inactive neurons: If some neurons are not activated, you can try increasing their input, or changing their weights so that they become activated.
Data processing: If the problem is caused by data processing, you can try modifying the way the data is processed, such as rescaling or normalizing the data.
Needs to be analyzed and adjusted for specific situations to improve the performance and accuracy of the neural network.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
