Artificial Intelligence (AI) is the broad concept of using software and hardware to perform tasks that typically require human intelligence. Within AI, there are two primary historical approaches: Rule-based systems (Expert Systems), where humans define explicit logic, and Machine Learning (ML), where machines discover rules from data without pre-set instructions. Neural Networks are a specific form of ML that simulate the human brain's structure. Deep Learning is a specialized implementation of neural networks that utilizes multiple hidden layers (depth) to improve performance and computational efficiency.

Cloudflare R2 offers 10GB of free monthly storage and is compatible with the AWS S3 API. Note that a credit card or PayPal-linked debit card is required for registration.

Hailuo AI is a video generation platform by MiniMax, frequently used for creating modified or stylized video content.

Jimeng AI, developed by Douyin (ByteDance), is a high-reputation AI platform for image and video generation. It features a "Story Creation" (故事创作) tool that allows users to generate videos with narrative plots based on specific scene breakdowns.

Deep Learning is a specific implementation of neural networks that enables effective computation across multiple layers of neurons. It consists of an input layer, an output layer, and numerous intermediate layers (hidden layers). The 'depth' refers to the ability to construct networks with thousands of hidden layers, significantly increasing performance compared to shallow networks.
