生成式预训练 Transformer（GPT）是现代人工智能中的一个重要突破，驱动了许多尖端的自然语言处理（NLP）应用。Generative Pre-trained Transformer (GPT) is a significant breakthrough in modern artificial intelligence, driving many cutting-edge applications in natural language processing (NLP). 在本文中，我们将通过更复杂的代码示例、详细的可视化图表，以及对其他 NLP 模型的比较，深入探讨 GPT 的工作原理、局限性及其在实际应用中的潜力。In this article, we will explore the working principles, limitations, and potential of GPT in practical applications through more complex code examples, detailed visualizations, and comparisons with other NLP

Backpropagation is a fundamental algorithm in training neural networks. Let’s break it down step by step:反向传播是训练神经网络的基本算法。让我们一步步来解析它: Imagine a simple neural network with three layers: input, hidden, and output.想象一个简单的三层神经网络:输入层、隐藏层和输出层。 Each circle represents a neuron, and the lines represent the connections (weights) between neurons.每个圆圈代表一个神经元,线条代表神经元之间的连接(权重)。 Data flows from left to right. Each neuron receives inputs, processes them, and
