Pre-Training Large Models: How Pre-Training Makes Models Smarter
Learn how pre-training, parameter initialization, forward propagation, and loss functions optimize neural networks for efficient data classification.
Welcome to the "Practical Application of AI Large Language Model Systems" Series
Last class, I introduced the internal structure of the model. To understand it better, we reviewed the model's implementation principles. I mentioned that the training process involves continually adjusting weights. More precisely, it also includes adjusting biases. So, training involves constantly adjusting weights and biases using backpropagation, loss functions, etc.
We didn't dive into details before, but in this class, we'll go through the pre-training process with a simple example.
We'll use a three-layer neural network model for data classification.
This model takes two input variables: study time and sleep time, and predicts whether a student will pass an exam.
We'll follow the usual model training steps, but won't repeat previously covered content.
