Prototypical networks learn a metric space in which classification can be performed by computing Euclidean distances to prototype representations of each class. The few-shot training set is first fed to the hallucinator; it produces an expanded training set, which is then used by the learner. In this paper, we show that both supervised few-shot learning and semi-supervised few-shot learning can be In experiments, we confirm our theoretical findings, present encouraging results for few-shot learning and contrast the bilevel approach against classical approaches for learning-to-learn. Meta Learning / Learning to Learn / One Shot Learning / Few Shot Learning - floodsung/Meta-Learning-Papers. Thus, deep networks seem less useful when the goal is to learn a new concept on the fly, from a few or even a single example as in one shot learning. Few-shot learning is the practice of feeding a learning model with a very small amount of training data, contrary to normal practice of using a large data. Relying on the default parameters and not performing Hyperparameter Optimization can have a significant impact on the model’s performance for Deep Learning.

The direction of travel has been to ally a narrow-focus learning algorithm with an algorithm that learns at a less granular level across a number of areas or classes. These problems are usually tackled by using generative models [18, 13] or, in a discriminative setting, using ad-hoc solutions such as exemplar support vector machines (SVMs) [14]. Noise: Noise levels are often quite high in the observations made via randomized experiments, especially compared to typical machine learning applications of Bayesian optimization like hyperparameter tuning. optimization (LEO), achieves state-of-the-art performance on the competitive miniImageNet and tieredImageNet few-shot classification tasks.
