Advanced Techniques and Concepts in Computer Vision
Transfer Learning
Leveraging Pre-trained Models
In transfer learning, a pre-trained model, typically trained on a large dataset, is used as a starting point for a new task. This can significantly reduce training time and improve performance, especially when dealing with limited datasets.
- Fine-tuning: The pre-trained model’s final layers are replaced or adjusted to suit the new task.
- Feature extraction: The pre-trained model’s intermediate layers are used to extract features, which can then be fed into a new classifier.
Example: A CNN pre-trained on ImageNet can be fine-tuned for a medical image classification task, leveraging the knowledge gained from the large-scale dataset.
Reinforcement Learning
Learning Through Interaction
Reinforcement learning agents learn by interacting with an environment, receiving rewards or penalties based on their actions. The goal is to maximize cumulative rewards over time.
- State: The current situation of the agent.
- Action: The choices available to the agent.
- Reward: A numerical value indicating the outcome of an action.
Algorithms:
- Q-learning: A model-free algorithm that learns a Q-value function, which estimates the expected future reward.
- Policy gradients: A family of algorithms that directly optimize the agent’s policy (mapping from states to actions).
- Deep Q-networks (DQN): Combine deep learning with Q-learning for complex tasks.
Example: A self-driving car can learn to navigate roads by interacting with the environment, receiving rewards for safe driving and penalties for accidents.
Explainable AI (XAI)
Understanding Model Decisions
XAI techniques aim to make AI models more transparent and understandable, especially for complex models like deep neural networks.
- Feature importance: Identifying the most influential features in a model’s decision.
- LIME (Local Interpretable Model-Agnostic Explanations): Creating simpler, linear models to explain the predictions of complex models.
- SHAP (SHapley Additive exPlanations): Attributing the contribution of each feature to a prediction.
Example: A medical diagnosis model can be explained using XAI to help doctors understand the reasoning behind the predictions and make more informed decisions.
Ethical AI
Addressing Bias and Fairness
Ethical AI is concerned with ensuring that AI systems are developed and used responsibly, addressing issues like bias, fairness, and privacy.
- Bias mitigation: Identifying and addressing biases in training data and algorithms.
- Fairness evaluation: Assessing the fairness of AI systems across different groups.
- Privacy protection: Ensuring that AI systems handle personal data responsibly.
Example: A facial recognition system must be designed to avoid biases against certain demographics and protect individuals’ privacy.
