A neural network, or artificial neural network, is a type of computing architecture that is based on a model of how a human brain functions — hence the name "neural." Neural networks are made up of a collection of processing units called "nodes." These nodes pass data to each other, j...

As the name suggests, neural networks are inspired by the brain. A neural network is designed to mimic how our brains work to recognize complex patterns and improve over time. Neural networks train themselves to handle large datasets, recognize patterns in that data, and then predict the output...
A GPT, or “generative pre-trained transformer,” is a family of advanced AI models developed by OpenAI. Designed to understand and generate humanlike text, a GPT uses a transformer architecture to perform tasks like answering questions, summarizing, and translating. Over time, OpenAI’s models ...
What is a Neural Network 让我们从一个房价预测的例子开始讲起 假设你有一个包含六栋房子信息的数据集。信息中包含房屋的面积以及房屋价格。这时,你想要根据房屋面积拟合一个预测房价的函数 如果你对线性回归($Linear\ Regression$)很熟悉,你可能会说:“好吧,让我们用这些数据拟合一条直线。”于是你可能会得到...
To remedy this, LSTM networks have “cells” in the hidden layers of the artificial neural network, which have 3 gates: an input gate, an output gate and a forget gate. These gates control the flow of information that is needed to predict the output in the network. For example, if gend...
GPT-3 was trained on roughly 500 billion tokens. All this training is used to create a complex, many-layered, weighted algorithm modeled after the human brain, called a deep learning neural network. It's what allows GPT-3 to understand patterns and relationships in the text data and tap ...
simultaneously instead of one at a time, as seen in older architectures likerecurrent neural networks (RNNs)or long short-term memory (LSTM). This parallel processing allows transformers to understand complex relationships across entire texts, enabling GPT models to grasp context and meaning ...
GPT is also limited by the quality and quantity of the data because of this training. If the data is biased or incomplete, it will affect the accuracy of GPT’s responses. Conclusion GPT is a form of deep learning. It uses a neural network with many layers to analyze and learn patterns...
GPT-3, or the third-generation Generative Pre-trained Transformer, is a neural network machine learning (ML) model trained using internet data to generate any type of text. Developed byOpenAI, it requires a small amount of input text to generate large volumes of relevant and sophisticated machin...
