A Novel Approach to Dropped Pronoun Translation
Dropped Pronouns (DP) in which pronouns are frequently dropped in the source language but should be retained in the target language are challenge in machine translation. In response to this problem, we propose a semisupervised approach to recall possibly missing pronouns in the translation. Firstly, we build training data for DP generation in which the DPs are automatically labelled according to the alignment information from a parallel corpus. Secondly, we build a deep learning-based DP generator for input sentences in decoding when no corresponding references exist. More specifically, the generation is two-phase: (1) DP position detection, which is modeled as a sequential labelling task with recurrent neural networks; and (2) DP prediction, which employs a multilayer perceptron with rich features. Finally, we integrate the above outputs into our translation system to recall missing pronouns by both extracting rules from the DP-labelled training data and translating the DP-generated input sentences. Experimental results show that our approach achieves a significant improvement of 1.58 BLEU points in translation performance with 66% F-score for DP generation accuracy

A Compact MIMO Antenna Design Using the Wideband Ground-Radiation Technique for 5G Terminals
This paper introduces a 4 × 4 multiple-input and multiple-output (MIMO) antenna application based on the conception of the characteristic mode of 5G terminals. The proposed antenna used a series capacitor and a parallel capacitor to control input impedance matching, while the resonance frequency was controlled by employing a resonance loop capacitor. In this way, we achieved a compact miniaturization antenna that uses ground radiation for the target 5G New Radio (NR) operating bands with n48, n77, and n78 bands. The simulation and measurement data revealed that the −6 dB bandwidth of the proposed antenna was approximately 1,240 MHz (ranging from 3.14 GHz to 4.38 GHz), while the efficiency also improved from 38.7% (reference) to 49.1% (proposed) within the 3 GHz to 4.6 GHz range. Furthermore, the radiation pattern exhibited satisfactory radiation performance. Therefore, it was concluded that the proposed 4 × 4 MIMO antenna set technology has promising prospects for application in 5G communication terminals in the future
Solitude profiles and psychological adjustment in Chinese late adolescence: a person-centered research
Objectives: From the perspective of person-centered research, the present study aimed to identify the potential profiles of solitude among late adolescents based on their solitary behavior, motivation, attitude, and time alone. In addition, to echo the paradox of solitude, we further explored the links between solitude profiles and adjustment outcomes.Methods: The participants of the study were 355 late adolescents (56.34% female, M age = 19.71 years old) at three universities in Shanghai, China. Measures of solitary behavior, autonomous motivation for solitude, attitude toward being alone, and time spent alone were collected using adolescents' self-report assessments. The UCLA Loneliness Scale, the Beck Depression Inventory, and the Basic Psychological Needs Scales were measured as indices of adjustment.Results: Latent profile analysis revealed four distinct groups: absence of the aloneness group (21.13%), the positive motivational solitude group (29.01%), the negative motivational solitude group (38.03%), and the activity-oriented solitude group (11.83%). Differences emerged among these four groups in terms of loneliness, depressive symptoms, and basic needs satisfaction, with adolescents in the negative motivational solitude group facing the most risk of psychological maladjustment.Conclusion: Findings revealed the possible heterogeneous nature of solitude among Chinese late adolescents and provided a theoretical basis for further understanding of adolescents' solitary state
Go From the General to the Particular: Multi-Domain Translation with Domain Transformation Networks
The key challenge of multi-domain translation lies in simultaneously encoding
both the general knowledge shared across domains and the particular knowledge
distinctive to each domain in a unified model. Previous work shows that the
standard neural machine translation (NMT) model, trained on mixed-domain data,
generally captures the general knowledge, but misses the domain-specific
knowledge. In response to this problem, we augment NMT model with additional
domain transformation networks to transform the general representations to
domain-specific representations, which are subsequently fed to the NMT decoder.
To guarantee the knowledge transformation, we also propose two complementary
supervision signals by leveraging the power of knowledge distillation and
adversarial learning. Experimental results on several language pairs, covering
both balanced and unbalanced multi-domain translation, demonstrate the
effectiveness and universality of the proposed approach. Encouragingly, the
proposed unified model achieves comparable results with the fine-tuning
approach that requires multiple models to preserve the particular knowledge.
Further analyses reveal that the domain transformation networks successfully
capture the domain-specific knowledge as expected.Comment: AAAI 202
Large Language Models Meet Harry Potter: A Bilingual Dataset for Aligning Dialogue Agents with Characters
In recent years, Dialogue-style Large Language Models (LLMs) such as ChatGPT
and GPT4 have demonstrated immense potential in constructing open-domain
dialogue agents. However, aligning these agents with specific characters or
individuals remains a considerable challenge due to the complexities of
character representation and the lack of comprehensive annotations. In this
paper, we introduce the Harry Potter Dialogue (HPD) dataset, designed to
advance the study of dialogue agents and character alignment. The dataset
encompasses all dialogue sessions (in both English and Chinese) from the Harry
Potter series and is annotated with vital background information, including
dialogue scenes, speakers, character relationships, and attributes. These
extensive annotations may empower LLMs to unlock character-driven dialogue
capabilities. Furthermore, it can serve as a universal benchmark for evaluating
how well can a LLM aligning with a specific character. We benchmark LLMs on HPD
using both fine-tuning and in-context learning settings. Evaluation results
reveal that although there is substantial room for improvement in generating
high-quality, character-aligned responses, the proposed dataset is valuable in
guiding models toward responses that better align with the character of Harry
Potter.Comment: 14 page
Performance Analysis and Optimal Allocation of Layered Defense M/M/N Queueing Systems
One important mission of strategic defense is to develop an integrated layered Ballistic Missile Defense System (BMDS). Motivated by the queueing theory, we presented a work for the representation, modeling, performance simulation, and channels optimal allocation of the layered BMDS M/M/N queueing systems. Firstly, in order to simulate the process of defense and to study the Defense Effectiveness (DE), we modeled and simulated the M/M/N queueing system of layered BMDS. Specifically, we proposed the M/M/N/N and M/M/N/C queueing model for short defense depth and long defense depth, respectively; single target channel and multiple target channels were distinguished in each model. Secondly, we considered the problem of assigning limited target channels to incoming targets, we illustrated how to allocate channels for achieving the best DE, and we also proposed a novel and robust search algorithm for obtaining the minimum channel requirements across a set of neighborhoods. Simultaneously, we presented examples of optimal allocation problems under different constraints. Thirdly, several simulation examples verified the effectiveness of the proposed queueing models. This work may help to understand the rules of queueing process and to provide optimal configuration suggestions for defense decision-making
GPT4Video: A Unified Multimodal Large Language Model for lnstruction-Followed Understanding and Safety-Aware Generation
While the recent advances in Multimodal Large Language Models (MLLMs)
constitute a significant leap forward in the field, these models are
predominantly confined to the realm of input-side multimodal comprehension,
lacking the capacity for multimodal content generation. To fill this gap, we
present GPT4Video, a unified multi-model framework that empowers Large Language
Models (LLMs) with the capability of both video understanding and generation.
Specifically, we develop an instruction-following-based approach integrated
with the stable diffusion generative model, which has demonstrated to
effectively and securely handle video generation scenarios. GPT4Video offers
the following benefits: 1) It exhibits impressive capabilities in both video
understanding and generation scenarios. For example, GPT4Video outperforms
Valley by 11.8\% on the Video Question Answering task, and surpasses NExt-GPT
by 2.3\% on the Text to Video generation task. 2) it endows the LLM/MLLM with
video generation capabilities without requiring additional training parameters
and can flexibly interface with a wide range of models to perform video
generation. 3) it maintains a safe and healthy conversation not only in
output-side but also the input side in an end-to-end manner. Qualitative and
qualitative experiments demonstrate that GPT4Video holds the potential to
function as a effective, safe and Humanoid-like video assistant that can handle
both video understanding and generation scenarios
