Landau-Zener-Stuckelberg interference in a multi-anticrossing system
We propose a universal analytical method to study the dynamics of a
multi-anticrossing system subject to driving by one single large-amplitude
triangle pulse, within its time scales smaller than the dephasing time. Our
approach can explain the main features of the Landau-Zener-Stuckelberg
interference patterns recently observed in a tripartite system [Nature
Communications 1:51 (2010)]. In particular, we focus on the effects of the size
of anticrossings on interference and compare the calculated interference
patterns with numerical simulations. In addition, Fourier transform of the
patterns can extract information on the energy level spectrum.Comment: 6 pages, 5 figure
NYCU-TWO at Memotion 3: Good Foundation, Good Teacher, then you have Good Meme Analysis
This paper presents a robust solution to the Memotion 3.0 Shared Task. The
goal of this task is to classify the emotion and the corresponding intensity
expressed by memes, which are usually in the form of images with short captions
on social media. Understanding the multi-modal features of the given memes will
be the key to solving the task. In this work, we use CLIP to extract aligned
image-text features and propose a novel meme sentiment analysis framework,
consisting of a Cooperative Teaching Model (CTM) for Task A and a Cascaded
Emotion Classifier (CEC) for Tasks B&C. CTM is based on the idea of knowledge
distillation, and can better predict the sentiment of a given meme in Task A;
CEC can leverage the emotion intensity suggestion from the prediction of Task C
to classify the emotion more precisely in Task B. Experiments show that we
achieved the 2nd place ranking for both Task A and Task B and the 4th place
ranking for Task C, with weighted F1-scores of 0.342, 0.784, and 0.535
respectively. The results show the robustness and effectiveness of our
framework. Our code is released at github.Comment: De-Factify 2: Second Workshop on Multimodal Fact Checking and Hate
