pooljuhendatud

Pooljuhendatud is a term used in the field of artificial intelligence and machine learning to describe a system or model that is guided or controlled by a pool of data. This pool of data typically consists of a large and diverse set of examples, which are used to train the model. The term "pool" in this context refers to the collection of data points, which can be labeled or unlabeled, depending on the type of learning task.

Pooljuhendatud systems are often used in supervised learning, where the model is trained on a labeled dataset. In this case, the pool of data consists of input-output pairs, where the input is a set of features and the output is the corresponding label or target value. The model learns to map inputs to outputs by minimizing the difference between its predictions and the true labels.

Pooljuhendatud systems can also be used in unsupervised learning, where the model is trained on an unlabeled dataset. In this case, the pool of data consists of input features only, and the model learns to find patterns or structures in the data without any guidance from labels.

One of the key advantages of pooljuhendatud systems is their ability to handle large and complex datasets. By using a pool of data, these systems can learn from a wide range of examples and generalize well to new, unseen data. Additionally, pooljuhendatud systems can be used to solve a variety of tasks, including classification, regression, and clustering.

However, pooljuhendatud systems also have some limitations. For example, they require a large and diverse set of data to be effective, which can be difficult to obtain in some domains. Additionally, these systems can be computationally expensive to train, especially when dealing with large datasets.

In summary, pooljuhendatud is a term used to describe a system or model that is guided or controlled by a pool of data. These systems are widely used in machine learning and have the ability to handle large and complex datasets. However, they also have some limitations, including the need for a large and diverse set of data and the potential for high computational costs.
