- Abstract: This paper presents SPeCiaL: a method for unsupervised pretraining of
representations tailored for continual learning. Our approach devises a
meta-learning objective that differentiates through a sequential learning
process. Specifically, we train a linear model over the representations to
match different augmented views of the same image together, each view presented
sequentially. The linear model is then evaluated on both its ability to
classify images it just saw, and also on images from previous iterations. This
gives rise to representations that favor quick knowledge retention with minimal
forgetting. We evaluate SPeCiaL in the Continual Few-Shot Learning setting, and
show that it can match or outperform other supervised pretraining approaches.

Humans possess remarkable ability to accurately classify new, unseen images after being exposed to only a few examples.
For artificial neural network models, determining the most relevant features for distinguishing between two images with limited samples presents a challenge.
We propose an intra-task mutual attention method for few-shot learning, that involves splitting the support and query samples into patches.

We show that existing online continually trained deep networks produce inferior representations compared to a simple pre-defined random transforms.
We then train a simple linear classifier on top without storing any exemplars, processing one sample at a time in an online continual learning setting.
Our study reveals the significant limitations of representation learning, particularly in low-exemplar and online continual learning scenarios.

We find that SLIP enjoys the best of both worlds: better performance than self-supervision and language supervision.

Real-world imagery is often characterized by a significant imbalance of the number of images per class, leading to long-tailed distributions.
In this work, we introduce a new framework, by making the key observation that a feature representation learned with instance sampling is far from optimal in a long-tailed setting.
Our main contribution is a new training method, that leverages knowledge distillation to enhance feature representations.

Recent gains in performance come from training instance classification models, treating each image and it's augmented versions as samples of a single class.
We demonstrate that approaches like MOCO and PIRL learn occlusion-invariant representations.
Second, we demonstrate that these approaches obtain further gains from access to a clean object-centric training dataset like Imagenet.
