Introduction
A dynamic model in machine learning refers to a type of model that can adjust its behavior over time in response to changes in its environment or new information. The dynamic model is frequently or even continuously retrained. It is also known as an online model. Dynamic models are especially beneficial in situations where the environment or data being used to train a model is constantly shifting.
The opposite of the dynamic model is static model.
Key Characteristics of Dynamic Models
Dynamic models stand out from other types of machine learning models due to several key characteristics. These characteristics include:
- Adaptability: Dynamic models are capable of adapting to changes in their environment or new information that is presented. This means they can modify their behavior and predictions in real-time based on the most up-to-date data available.
- Feedback: Dynamic models often include feedback mechanisms that enable them to learn from errors and improve performance over time. This feedback can come from various sources such as user input, sensor data, or other types of external signals.
- Statefulness: Dynamic models typically maintain an internal state that reflects their current understanding of the environment. This state can be updated as new information is received, enabling the model to continuously adjust its predictions and behavior in response.
- Complexity: Dynamic models tend to be more intricate than other types of models due to the need to incorporate feedback and maintain an internal state. While this complexity makes them harder to train and optimize, it also allows them to perform well across a variety of environments.
How Dynamic Models Work
Explain Like I'm 5 (ELI5)
Dynamic models in machine learning are like robots that can adjust their mind and behavior based on what they observe and hear. Through learning from errors, dynamic models become better at what they do over time. Different types of dynamic models exist, such as ones based on reinforcement learning or ones using reinforcement programming.
