Enhancing Few-Shot Image Classification with Unlabelled Examples

2020-06-17 · Peyman Bateni, Jarred Barber, Jan-Willem van de Meent, Frank Wood

We develop a transductive meta-learning method that uses unlabelled instances to improve few-shot image classification performance. Our approach combines a regularized Mahalanobis-distance-based soft k-means clustering procedure with a modified state of the art neural adaptive feature extractor to achieve improved test-time classification accuracy using unlabelled data. We evaluate our method on transductive few-shot learning tasks, in which the goal is to jointly predict labels for query (test) examples given a set of support (training) examples. We achieve state of the art performance on the Meta-Dataset, mini-ImageNet and tiered-ImageNet benchmarks. All trained models and code have been made publicly available at github.com/plai-group/simple-cnaps.

On the Importance of Distractors for Few-Shot Classification

2021-09-20 · ICCV 2021 10 · Rajshekhar Das, Yu-Xiong Wang, JoséM. F. Moura

Few-shot classification aims at classifying categories of a novel task by learning from just a few (typically, 1 to 5) labelled examples. An effective approach to few-shot classification involves a prior model trained on…

Automatically Discovering and Learning New Visual Categories with Ranking Statistics

2020-02-13 · ICLR 2020 1 · Kai Han, Sylvestre-Alvise Rebuffi, Sebastien Ehrhardt, Andrea Vedaldi 외

We tackle the problem of discovering novel classes in an image collection given labelled examples of other classes. This setting is similar to semi-supervised learning, but significantly harder because there are no label…
