Fine-grained image recognition is a longstanding computer vision challenge that focuses on differentiating objects belonging to multiple subordinate categories within the same meta-category. Since images meta-category usually share similar visual appearances, mining discriminative cues key distinguishing fine-grained categories.

We present a machine learning approach to sentiment classification on twitter messages (tweets). classify each tweet into two categories: polar and non-polar. Tweets with positive or negative are considered polar. They non-polar otherwise. Sentiment analysis of tweets can potentially benefit different parties, such as consumers marketing researchers, for obtaining opinions products services. methods text normalization the noisy their respect polarity. experiment mixture model generation...

Structured belief states are crucial for user goal tracking and database query in task-oriented dialog systems. However, training trackers often requires expensive turn-level annotations of every utterance. In this paper we aim at alleviating the reliance on state labels building end-to-end systems, by leveraging unlabeled data towards semi-supervised learning. We propose a probabilistic model, called LAtent BElief State (LABES) where represented as discrete latent variables jointly modeled...

Topology impacts important network performance metrics, including link utilization, throughput and latency, is of central importance to operators. However, due the combinatorial nature topology, it extremely difficult obtain an optimal solution, especially since topology planning in networks also often comes with management-specific constraints. As a result, local optimization hand-tuned heuristic methods from human experts adopted practice. Yet, cannot cover global design space while taking...

Early exiting has become a promising approach to improving the inference efficiency of deep networks. By structuring models with multiple classifiers (exits), predictions for "easy" samples can be generated at earlier exits, negating need executing deeper layers. Current multi-exit networks typically implement linear intermediate layers, compelling low-level features encapsulate high-level semantics. This sub-optimal design invariably undermines performance later exits. In this paper, we...

A Dialogue State Tracker (DST) is a core component of modular task-oriented dialogue system. Tremendous progress has been made in recent years. However, the major challenges remain. The state-of-the-art accuracy for DST below 50% multi-domain task. learnable any new domain requires large amount labeled in-domain data and training from scratch. In this paper, we propose Meta-Reinforced Multi-Domain Generator (MERET). Our first contribution to improve accuracy. We enhance neural model based...

Self-supervised entity alignment (EA) aims to link equivalent entities across different knowledge graphs (KGs) without the use of pre-aligned pairs. The current state-of-the-art (SOTA) self-supervised EA approach draws inspiration from contrastive learning, originally designed in computer vision based on instance discrimination and loss, suffers two shortcomings. Firstly, it puts unidirectional emphasis pushing sampled negative far away rather than pulling positively aligned pairs close, as...

Graphs are widely used to represent the relations among entities. When one owns complete data, an entire graph can be easily built, therefore performing analysis on is straightforward. However, in many scenarios, it impractical centralize data due privacy concerns. An organization or party only keeps a part of whole i.e., isolated from different parties. Recently, Federated Learning (FL) has been proposed solve isolation issue, mainly for Euclidean data. It still challenge apply FL because...

Recently, two approaches, fine-tuning large pre-trained language models and variational training, have attracted significant interests, separately, for semi-supervised end-to-end task-oriented dialog (TOD) systems. In this paper, we propose Variational Latent-State GPT model (VLS-GPT), which is the first to combine strengths of approaches. Among many options models, generative inference learning TOD system, both as auto-regressive based on GPT-2, can be further trained over a mix labeled...

Knowledge graphs are widely used in industrial applications, making error detection crucial for ensuring the reliability of downstream applications. Existing methods often fail to effectively leverage fine-grained subgraph information and rely solely on fixed graph structures, while also lacking transparency their decision-making processes, which results suboptimal performance. In this paper, we propose a novel Multi-Agent framework Graph Error Detection (MAKGED) that utilizes multiple large...

Numerical investigations aiming to determine the universality class of critical motility-induced phase separation (MIPS) in two dimensions (2D) have resulted inconclusive findings. Here, using finite-size scaling results obtained from large-scale computer simulations, we find that static and dynamic exponents associated with 3D MIPS all closely match those Ising a conserved scalar order parameter. This finding is corroborated by fluctuating hydrodynamic description dynamics parameter field...

With the rapid advancement of Large Language Models (LLMs), safety LLMs has been a critical concern requiring precise assessment. Current benchmarks primarily concentrate on single-turn dialogues or single jailbreak attack method to assess safety. Additionally, these have not taken into account LLM's capability identifying and handling unsafe information in detail. To address issues, we propose fine-grained benchmark SafeDialBench for evaluating across various attacks multi-turn dialogues....
