What is One-shot Learning?

One-shot learning is a machine learning technique that trains models to classify objects or patterns based on a single example per class. It is commonly used in computer vision and object categorization tasks, where the model learns to recognize new classes with minimal training data. This approach is beneficial for scenarios where collecting extensive datasets is challenging or impractical, as it can achieve good performance with limited examples.

What are the applications of One-shot Learning in AI?

In the field of artificial intelligence, one-shot learning finds applications in various areas such as facial recognition, handwriting recognition, and image classification. For instance, in facial recognition systems, one-shot learning enables the model to identify individuals based on a single image, making it useful for security and surveillance applications.

Similarly, in handwritten character recognition, the model can learn to classify diverse handwriting styles with just a few examples per character, showcasing the versatility of one-shot learning in different AI tasks.

How does One-shot Learning differ from few-shot learning?

One-shot learning differs from few-shot learning primarily in the amount of training data available for each class. While one-shot learning requires only a single example per class for training, few-shot learning involves training the model with a small number of examples, typically ranging from one to five instances per class. This distinction impacts the model's ability to generalize to new classes, with one-shot learning focusing on rapid adaptation to novel categories with minimal data, whereas few-shot learning allows for a slightly broader learning capability with slightly more examples per class.
