- Abstract summary: Generalized few-shot semantic segmentation was introduced to move beyond only evaluating few-shot segmentation models on novel classes.
While all approaches currently are based on meta-learning, they perform poorly and saturate in learning after observing only a few shots.
We propose the first fine-tuning solution, and demonstrate that it addresses the saturation problem while achieving state-of-art results on two datasets.

- Abstract: Generalized few-shot semantic segmentation was introduced to move beyond only
evaluating few-shot segmentation models on novel classes to include testing
their ability to remember base classes. While all approaches currently are
based on meta-learning, they perform poorly and saturate in learning after
observing only a few shots. We propose the first fine-tuning solution, and
demonstrate that it addresses the saturation problem while achieving
state-of-art results on two datasets, PASCAL-$5^i$ and COCO-$20^i$. We also
show it outperforms existing methods whether fine-tuning multiple final layers
or only the final layer. Finally, we present a triplet loss regularization that
shows how to redistribute the balance of performance between novel and base
categories so that there is a smaller gap between them.

This paper considers incremental few-shot learning, which requires a model to continually recognize new categories with only a few examples.
Our study shows that existing methods severely suffer from catastrophic forgetting, a well-known problem in incremental learning.
We propose to search for flat local minima of the base training objective function and then fine-tune the model parameters within the flat region on new tasks.

We present an in-depth study on few-shot video classification by making three contributions.
First, we perform a consistent comparative study on the existing metric-based methods to figure out their limitations in representation learning.
Second, we discover that there is a high correlation between the novel action class and the ImageNet object class, which is problematic in the few-shot recognition setting.
Third, we present a new benchmark with more base data to facilitate future few-shot video classification without pre-training.

State-of-the-art semantic segmentation methods require sufficient labeled data to achieve good results.
Few-shot segmentation is proposed to tackle this problem by learning a model that quickly adapts to new classes with a few labeled support samples.
Theses frameworks still face the challenge of generalization ability reduction on unseen classes due to inappropriate use of high-level semantic information.
