Actual features of new classes and pseudo-features of past classes are fed into a linear classifier which is trained incrementally to discriminate between all classes.

Mainstream methods need to store two deep models since they integrate new classes using fine tuning with knowledge distillation from the previous incremental state.

Since memory is bounded, old classes are learned with fewer images than new classes and an imbalance due to incremental learning is added to the initial dataset imbalance.

Here, we introduce a new active learning method which is designed for imbalanced datasets.

It consists in learning a model on a small amount of annotated data (annotation budget) and in choosing the best set of points to annotate in order to improve the previous model and gain in generalization.

We introduce a two-step learning process which allows the transfer of bias correction parameters between reference and target datasets.

Learning continually from non-stationary data streams is a long-standing goal and a challenging problem in machine learning.

The approach relies on three components: (1) a set of visual objects with associated situation impact ratings obtained by crowdsourcing, (2) a corresponding set of object detectors for mining users' photos and (3) a ground truth dataset made of 500 visual user profiles which are manually rated per situation.

A second type of approaches fix the deep model size and introduce a mechanism whose objective is to ensure a good compromise between stability and plasticity of the model.

It leverages initial classifier weights which provide a strong representation of past classes because they are trained with all class data.

Most existing algorithms make two strong hypotheses which reduce the realism of the incremental scenario: (1) new data are assumed to be readily annotated when streamed and (2) tests are run with balanced datasets while most real-life datasets are actually imbalanced.

When the number of classes is large, classes are usually represented by semantic class prototypes learned automatically from unannotated text collections.

The problem is non trivial if the agent runs on a limited computational budget and has a bounded memory of past data.
