- Abstract summary: We constructed Deep Neural Network models to predict forthcoming engagement of citizen scientists in a Swedish marine project.
Based on the results, it is possible to predict whether an annotator will remain active in future sessions.
The novelty of our models lies in the use of Deep Neural Networks and the sequence of volunteer annotations.

- Abstract: Citizen science and machine learning should be considered for monitoring the
coastal and ocean environment due to the scale of threats posed by climate
change and the limited resources to fill knowledge gaps. Using data from the
annotation activity of citizen scientists in a Swedish marine project, we
constructed Deep Neural Network models to predict forthcoming engagement. We
tested the models to identify patterns in annotation engagement. Based on the
results, it is possible to predict whether an annotator will remain active in
future sessions. Depending on the goals of individual citizen science projects,
it may also be necessary to identify either those volunteers who will leave or
those who will continue annotating. This can be predicted by varying the
threshold for the prediction. The engagement metrics used to construct the
models are based on time and activity and can be used to infer latent
characteristics of volunteers and predict their task interest based on their
activity patterns. They can estimate if volunteers can accomplish a given
number of tasks in a certain amount of time, identify early on who is likely to
become a top contributor or identify who is likely to quit and provide them
with targeted interventions. The novelty of our predictive models lies in the
use of Deep Neural Networks and the sequence of volunteer annotations. A
limitation of our models is that they do not use embeddings constructed from
user profiles as input data, as many recommender systems do. We expect that
including user profiles would improve prediction performance.

A self-driving vehicle (SDV) must be able to perceive its surroundings and predict the future behavior of other traffic participants.
Existing works either perform object detection followed by trajectory of the detected objects, or predict dense occupancy and flow grids for the whole scene.
This motivates our unified approach to perception and future prediction that implicitly represents occupancy and flow over time with a single neural network.

Prediction [56.001808843574395]
Selective prediction aims to learn a reliable model that abstains from making predictions when uncertain.
Active learning aims to lower the overall labeling effort, and hence human dependence, by querying the most informative examples.
In this work, we introduce a new learning paradigm, active selective prediction, which aims to query more informative samples from the shifted target domain.

Discovery in a Single Stream of Experience [63.75363908696257]
computational reinforcement learning seeks to construct an agent's perception of the world through predictions of future sensations.
An open challenge in this line of work is determining from the infinitely many predictions that the agent could possibly make which predictions might best support decision-making.
We introduce a meta-gradient descent process by which an agent learns what predictions to make, 2) the estimates for its chosen predictions, and 3) how to use those estimates to generate policies that maximize future reward.

We propose an Inception Residual Block (IRB) to detect temporal features in human poses.
Our main contribution is to propose a residual connection between input and the output of the inception block to have a continuity between the previously observed pose and the next predicted pose.
With this proposed architecture, it learns prior knowledge much better about human poses and we achieve much higher prediction accuracy as detailed in the paper.
