- Abstract: In recent years, scene text recognition is always regarded as a
sequence-to-sequence problem. Connectionist Temporal Classification (CTC) and
Attentional sequence recognition (Attn) are two very prevailing approaches to
tackle this problem while they may fail in some scenarios respectively. CTC
concentrates more on every individual character but is weak in text semantic
dependency modeling. Attn based methods have better context semantic modeling
ability while tends to overfit on limited training data. In this paper, we
elaborately design a Rectified Attentional Double Supervised Network (ReADS)
for general scene text recognition. To overcome the weakness of CTC and Attn,
both of them are applied in our method but with different modules in two
supervised branches which can make a complementary to each other. Moreover,
effective spatial and channel attention mechanisms are introduced to eliminate
background noise and extract valid foreground information. Finally, a simple
rectified network is implemented to rectify irregular text. The ReADS can be
trained end-to-end and only word-level annotations are required. Extensive
experiments on various benchmarks verify the effectiveness of ReADS which
achieves state-of-the-art performance.

Speech event detection is crucial for multimedia retrieval, involving the tagging of both semantic and acoustic events.
This paper tackles two primary challenges in speech event detection: the continual integration of new events without forgetting previous ones, and the disentanglement of semantic from acoustic events.
We propose a novel method, 'Double Mixture,' which merges speech expertise with robust memory mechanisms to enhance adaptability and prevent forgetting.

Scene text recognition (STR) is a challenging task that requires large-scale annotated data for training.
Most existing STR methods resort to synthetic data, which may introduce domain discrepancy and degrade the performance of STR models.
This paper proposes a novel semi-supervised learning method for STR that incorporates word-level consistency regularization from both visual and semantic aspects.

Key problem in zero-shot open vocabulary detection is how to align visual and text features, so that the detector performs well on unseen classes.
Previous approaches train the feature pyramid and detection head from scratch, which breaks the vision-text feature alignment established during pretraining.
We propose three methods to alleviate these issues. Firstly, a simple scheme is used to augment the text embeddings which prevents overfitting to a small number of classes seen during training.
Secondly, the feature pyramid network and the detection head are modified to include trainable shortcuts.
Finally, a self-training approach is used to leverage a larger corpus of

Temporal Action Localization [87.47977407022492]
This paper argues that learning by contextually comparing sequence-to-sequence distinctions offers an essential inductive bias in weakly-supervised action localization.
Under a differentiable dynamic programming formulation, two complementary contrastive objectives are designed, including Fine-grained Sequence Distance (FSD) contrasting and Longest Common Subsequence (LCS) contrasting.
Our method achieves state-of-the-art performance on two popular benchmarks.
