- Abstract: In this paper, we propose to utilize Automated Machine Learning to
automatically search architecture for deepfake detection. Unlike previous
works, our method benefits from the superior capability of deep learning while
relieving us from the high labor cost in the manual network design process. It
is experimentally proved that our proposed method not only outperforms previous
non-deep learning methods but achieves comparable or even better prediction
accuracy compared to previous deep learning methods. To improve the generality
of our method, especially when training data and testing data are manipulated
by different methods, we propose a multi-task strategy in our network learning
process, making it estimate potential manipulation regions in given samples as
well as predict whether the samples are real. Comparing to previous works using
similar strategies, our method depends much less on prior knowledge, such as no
need to know which manipulation method is utilized and whether it is utilized
already. Extensive experimental results on two benchmark datasets demonstrate
the effectiveness of our proposed method on deepfake detection.

We show how off-policy reinforcement learning can enable improved performance under assumptions that are similar but potentially even more practical than those of interactive imitation learning.
Our proposed method uses reinforcement learning with user intervention signals themselves as rewards.
This relaxes the assumption that intervening experts in interactive imitation learning should be near-optimal and enables the algorithm to learn behaviors that improve over the potential suboptimal human expert.

Experience Replay sample efficiency [7.806014635635933]
We propose a method that uses primitive behaviours that have been previously learned to solve simple tasks.
This guidance is not executed by a manually designed curriculum, but rather using a critic network to decide at each timestep whether or not to use the actions proposed.
We demonstrate the agents can learn a successful policy faster when using our proposed method, both in terms of sample efficiency and computation time.

Both politics and pandemics have recently provided ample motivation for the development of machine learning-enabled disinformation (a.k.a. fake news) detection algorithms.
Existing literature has focused primarily on the fully-automated case, but the resulting techniques cannot reliably detect disinformation on the varied topics, sources, and time scales required for military applications.
By leveraging an already-available analyst as a human-in-the-loop, canonical machine learning techniques of sentiment analysis, aspect-based sentiment analysis, and stance detection become plausible methods to use for a partially-automated disinformation detection system.
