The two presented their groundbreaking Logic Theorist, a computer program capable of proving certain mathematical theorems and often referred to as the first AI program. A year later, in 1957, Newell and Simon created the General Problem Solver algorithm that, despite failing to solve more complex ...

To answer the question, “what is good enough?”, it becomes necessary to distinguish between anAI model and an AI system as the unit of performance assessment. An AI model typically involves some input data, a pattern-matching algorithm, and an output classification. For example,...
not all data can be used to train AI models. Generative models require high-quality, unbiased data to operate. Moreover, some domains don’t have enough data to train a model. As an example, few 3D assets exist and they’re expensive to develop. Such areas will require significant resourc...
强化学习中智能体需要包含以下结构:模型(model)、算法(algoritihm)和代理(agent)。在外部文件夹中,model.py构建了前向网络,输入为当前的环境状态(state);算法,根据定义和损失函数更新模型;agent.py为负责算法与环境的交互,在交互过程中把生成的数据提供给 Algorithm 来更新模型( Model ),也就是数据和算法的交互一般...
In the early training stages, the model’s predictions aren’t very good. But each time the model predicts a token, it checks for correctness against the training data. Whether it’s right or wrong, a “backpropagation” algorithm adjusts the parameters—that is, the formulas’ coefficients—...
(结构化数据),另一个图灵奖获得者Yoshua Bengio将它拓展到了自然语言处理上,即NLP领域如何做distributed representation,起初你可能是对一个样本representation,但对自然语言处理来讲,它是sequence,需要表示sequence,并且单词之间的依赖关系如何表示,因此2003年Bengio提出了Nerual Probabilistic Language Model,这也是他获得图灵...
To create a foundation model, practitioners train a deep learning algorithm on huge volumes of relevant raw, unstructured, unlabeled data, such as terabytes or petabytes of data text or images or video from the internet. The training yields aneural networkof billions ofparametersencoded representation...
dating back to the 1960s when it was introduced in chatbots. It wasn't until 2014, however, with the introduction of generative adversarial networks (GANs) -- a type of machine learning algorithm -- that generative AI could createconvincingly authentic images, videos and audio of real people...
通过局部解释进行交互的方法是最常见的可解释 AI 方法,即给定一个预测器和一个目标决策,输入属性确定哪些输入变量与决策 "最相关",我们比较熟悉的 SHAP 解释模型(SHapley Additive exPlanation)、LIME 解释器(Local Interpretable Model-agnostic Explanations)都属于这一类方法。 基于局部解释方法的特点包括: 使用户能够...
