LSTM is a memory system for machines, helping them remember important information over time. It uses special 'gates' to decide what information to keep, update, or forget.
CNNs analyze images by breaking them down into smaller pieces and looking for patterns. They use layers of filters to detect features and recognize objects.
Transformers can understand entire documents at once, rather than reading word by word. They use attention mechanism to focus on important parts of the input.
These models are used in various applications like recommendation systems and virtual assistants, making life easier and more connected.
