Causal Factor Disentanglement for Few-Shot Domain Adaptation in Video Prediction

open access: yesEntropy, 2023
An important challenge in machine learning is performing with accuracy when few training samples are available from the target distribution. If a large number of training samples from a related distribution are available, transfer learning can be used to

Children’s information retrieval: beyond examining search strategies and interfaces [PDF]

open access: yes, 2008
The study of children’s information retrieval is still for the greater part untouched territory. Meanwhile, children can become lost in the digital information world, because they are confronted with search interfaces, both designed by and for adults ...

Twitter Self-Organization to the Edge of a Phase Transition: Discrete-Time Model and Effective Early Warning Signals in Phase Space

open access: yesComplexity, 2023
Many real-world systems of various origins are capable of self-organization to the edge of a phase transition, characterized by avalanche-like behavior. Therefore, it is important, by observing the behavior of early warning measures for dynamical series ...

Aligning Semantic in Brain and Language: A Curriculum Contrastive Method for Electroencephalography-to-Text Generation

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Electroencephalography-to-Text generation (EEG-to-Text), which aims to directly generate natural text from EEG signals has drawn increasing attention in recent years due to the enormous potential for Brain-computer interfaces.

Effective precursors for self-organization of complex systems into a critical state based on dynamic series data

open access: yesFrontiers in Physics, 2023
Many different precursors are known, but not all of which are effective, i.e., giving enough time to take preventive measures and with a minimum number of false early warning signals.

In-Context Retrieval-Augmented Language Models [PDF]

open access: yesTransactions of the Association for Computational Linguistics, 2023
Retrieval-Augmented Language Modeling (RALM) methods, which condition a language model (LM) on relevant documents from a grounding corpus during generation, were shown to significantly improve language modeling performance. In addition, they can mitigate
