Solution

To accurately respond to your request regarding learning-based approaches, I would typically need to see the figures you are referring to. However, I can provide an overview of commonly recognized learning-based approaches in machine learning and data science contexts.

1. Supervised Learning

In supervised learning, the algorithm is trained on labeled data, meaning that each training example includes an input-output pair. The objective is to learn a mapping from inputs to outputs, which can be used for prediction on new, unseen data. Common algorithms include linear regression, logistic regression, decision trees, and neural networks.

2. Unsupervised Learning

Unsupervised learning is used when the data does not have labeled outputs. The goal is to identify patterns or structures in the data. Clustering and association are typical tasks. Common algorithms include k-means clustering, hierarchical clustering, and principal component analysis (PCA).

3. Semi-Supervised Learning

Semi-supervised learning combines aspects of both supervised and unsupervised learning. It uses a small amount of labeled data along with a large amount of unlabeled data. This approach helps improve the learning accuracy when labeling data is expensive or time-consuming. Algorithms like self-training and co-training are often employed in this domain.

4. Reinforcement Learning

In reinforcement learning, an agent learns by interacting with an environment. It receives rewards or penalties for its actions and aims to maximize the cumulative reward over time. This type of learning is commonly used in robotics, game playing (like AlphaGo), and autonomous driving.

Conclusion

Each of these learning-based approaches addresses different types of problems and data scenarios. The choice of which approach to use often depends on the specific problem being solved, the nature of the available data, and the desired outcome. If you can provide the figures mentioned, I could give a more tailored analysis based on that specific information.
