The high feature dimensionality is a challenge in music emotion recognition. There is no common consensus on a relation between audio features and emotion. The MER system uses all available features to recognize emotion; however, this is not an optimal solution since it contains irrelevant data acting as noise. In this paper, we introduce a feature selection approach to eliminate redundant features for MER. We created a Selected Feature Set (SFS) based on the feature selection algorithm (FSA) and benchmarked it by training with two models, Support Vector Regression (SVR) and Random Forest (RF) and comparing them against with using the Complete Feature Set (CFS). The result indicates that the performance of MER has improved for both Random Forest (RF) and Support Vector Regression (SVR) models by using SFS. We found using FSA can improve performance in all scenarios, and it has potential benefits for model efficiency and stability for MER task.

We present SODA: the first publicly available, million-scale high-quality social dialogue dataset. Using SODA, we train COSMO: a generalizable conversation agent outperforming previous best-performing agents on both in- and out-of-domain datasets. In contrast to most existing crowdsourced, small-scale dialogue corpora, we distill 1.5M socially-grounded dialogues from a pre-trained language model (InstructGPT; Ouyang et al., 2022). Dialogues are distilled by contextualizing social commonsense knowledge from a knowledge graph (Atomic10x; West et al., 2022). Human evaluation shows that dialogues in SODA are more consistent, specific, and (surprisingly) natural than prior human-authored datasets - e.g., DailyDialog (Li et al., 2017), BlendedSkillTalk (Smith et al., 2020). In addition, extensive evaluations show that COSMO is significantly more natural and consistent on unseen datasets than best-performing dialogue models - e.g., GODEL (Peng et al., 2022), BlenderBot (Roller et al., 2021), DialoGPT (Zhang et al., 2020). Furthermore, it is sometimes even preferred to the original human-written gold responses. We make our data, models, and code public.

Pre-trained language models, despite their rapid advancements powered by scale, still fall short of robust commonsense capabilities. And yet, scale appears to be the winning recipe; after all, the largest models seem to have acquired the largest amount of commonsense capabilities. Or is it? In this paper, we investigate the possibility of a seemingly impossible match: can smaller language models with dismal commonsense capabilities (i.e., GPT-2), ever win over models that are orders of magnitude larger and better (i.e., GPT-3), if the smaller models are powered with novel commonsense distillation algorithms? The key intellectual question we ask here is whether it is possible, if at all, to design a learning algorithm that does not benefit from scale, yet leads to a competitive level of commonsense acquisition. In this work, we study the generative models of commonsense knowledge, focusing on the task of generating generics, statements of commonsense facts about everyday concepts, e.g., birds can fly. We introduce a novel commonsense distillation framework, I2D2, that loosely follows the Symbolic Knowledge Distillation of West et al. but breaks the dependence on the extreme-scale models as the teacher model by two innovations: (1) the novel adaptation of NeuroLogic Decoding to enhance the generation quality of the weak, off-the-shelf language models, and (2) self-imitation learning to iteratively learn from the model's own enhanced commonsense acquisition capabilities. Empirical results suggest that scale is not the only way, as novel algorithms can be a promising alternative. Moreover, our study leads to a new corpus of generics, Gen-A-Tomic, that is of the largest and highest quality available to date.

Automatic parsing of human anatomies at instance-level from 3D computed tomography (CT) scans is a prerequisite step for many clinical applications. The presence of pathologies, broken structures or limited field-of-view (FOV) all can make anatomy parsing algorithms vulnerable. In this work, we explore how to exploit and conduct the prosperous detection-then-segmentation paradigm in 3D medical data, and propose a steerable, robust, and efficient computing framework for detection, identification, and segmentation of anatomies in CT scans. Considering complicated shapes, sizes and orientations of anatomies, without lose of generality, we present the nine degrees-of-freedom (9-DoF) pose estimation solution in full 3D space using a novel single-stage, non-hierarchical forward representation. Our whole framework is executed in a steerable manner where any anatomy of interest can be directly retrieved to further boost the inference efficiency. We have validated the proposed method on three medical imaging parsing tasks of ribs, spine, and abdominal organs. For rib parsing, CT scans have been annotated at the rib instance-level for quantitative evaluation, similarly for spine vertebrae and abdominal organs. Extensive experiments on 9-DoF box detection and rib instance segmentation demonstrate the effectiveness of our framework (with the identification rate of 97.0% and the segmentation Dice score of 90.9%) in high efficiency, compared favorably against several strong baselines (e.g., CenterNet, FCOS, and nnU-Net). For spine identification and segmentation, our method achieves a new state-of-the-art result on the public CTSpine1K dataset. Last, we report highly competitive results in multi-organ segmentation at FLARE22 competition. Our annotations, code and models will be made publicly available at: https://github.com/alibaba-damo-academy/Med_Query.

Large language models (LLMs) have been shown to be able to perform new tasks based on a few demonstrations or natural language instructions. While these capabilities have led to widespread adoption, most LLMs are developed by resource-rich organizations and are frequently kept from the public. As a step towards democratizing this powerful technology, we present BLOOM, a 176B-parameter open-access language model designed and built thanks to a collaboration of hundreds of researchers. BLOOM is a decoder-only Transformer language model that was trained on the ROOTS corpus, a dataset comprising hundreds of sources in 46 natural and 13 programming languages (59 in total). We find that BLOOM achieves competitive performance on a wide variety of benchmarks, with stronger results after undergoing multitask prompted finetuning. To facilitate future research and applications using LLMs, we publicly release our models and code under the Responsible AI License.

We present state advantage weighting for offline reinforcement learning (RL). In contrast to action advantage $A(s,a)$ that we commonly adopt in QSA learning, we leverage state advantage $A(s,s^\prime)$ and QSS learning for offline RL, hence decoupling the action from values. We expect the agent can get to the high-reward state and the action is determined by how the agent can get to that corresponding state. Experiments on D4RL datasets show that our proposed method can achieve remarkable performance against the common baselines. Furthermore, our method shows good generalization capability when transferring from offline to online.

反转合是药物发现的主要任务。通过许多现有方法，它被称为生成图的问题。具体而言，这些方法首先识别反应中心，并相应地打破靶分子以生成合成子。反应物是通过顺序添加到合成图或直接添加正确的离开组来生成反应物。但是，两种策略都遭受了添加原子以来会导致长期的预测顺序，从而增加了产生难度，同时添加离开组只能考虑训练集中的序列，从而导致概括不佳。在本文中，我们提出了一个新颖的端到端图生成模型，用于逆转录合成预测，该模型顺序识别反应中心，生成合成子，并将基序添加到合成子中以生成反应物。由于化学有意义的基序比原子大，比离开组还小，因此与添加原子相比，与添加离开组相比，我们的方法的预测复杂性较低。基准数据集上的实验表明，所提出的模型显着胜过先前的最新算法。

由于复杂的腹部内形状和腹部器官之间的复杂形状和外观变化，从不同模态的CT成像中进行的准确且健壮的腹部多器官分割是一项具有挑战性的任务。在本文中，我们提出了一个具有分层空间特征调制的概率多器官分割网络，以捕获灵活的器官语义变体，并将学习的变体注入不同的特征图尺度，以进行指导分割。更具体地说，我们通过条件变异自动编码器设计一个输入分解模块，以在低维潜在空间和模型富有器官语义变化上学习器官特异性分布，该分布在输入图像上进行条件。 -NET解码器通过空间特征转换从层次上进行分层，该特征转换能够将变化转换为空间特征映射调制并指导细尺度分割的条件仿射转换参数。提出的方法对公开可用的腹部可用数据集进行了培训，并在其他两个开放数据集上进行了评估，即100个挑战/病理测试，从腹部腹部1K完全监督的腹部器官细分基准和90例TCIA+＆BTCV数据集中进行了90例病例。使用这些数据集用于四个腹部器官，肾脏，脾脏和胰腺，肾脏分数提高了7.3％，胰腺的骰子得分提高了7.7％，而胰腺的骰子得分提高了7.3％，而胰腺的较高速度比强度快7倍，较高的7倍基线分割方法（NNUNET和COTR）。

深度学习已被广​​泛用于医学图像细分和其他方面。但是，现有的医学图像分割模型的性能受到获得足够数量的高质量数据的挑战的限制。为了克服限制，我们提出了一个新的视觉医学图像分割模型LVIT（语言符合视觉变压器）。在我们的模型中，引入了医学文本注释，以弥补图像数据的质量缺陷。此外，文本信息可以在一定程度上指导伪标签的产生，并进一步保证半监督学习中伪标签的质量。我们还提出了指数伪标签迭代机制（EPI），以帮助扩展LVIT和像素级注意模块（PLAM）的半监督版本，以保留图像的局部特征。在我们的模型中，LV（语言视觉）损失旨在直接使用文本信息监督未标记图像的培训。为了验证LVIT的性能，我们构建了包含病理图像，X射线等的多模式医学分割数据集（图像 +文本）。实验结果表明，我们提出的LVIT在完全和半监督条件下具有更好的分割性能。代码和数据集可在https://github.com/huanglizi/lvit上找到。

尽管无监督的异常检测迅速发展，但现有的方法仍需要训练不同对象的单独模型。在这项工作中，我们介绍了完成具有统一框架的多个类别的异常检测。在如此具有挑战性的环境下，流行的重建网络可能属于“相同的快捷方式”，在这种捷径中，正常样本和异常样本都可以很好地恢复，因此无法发现异常值。为了解决这一障碍，我们取得了三个改进。首先，我们重新审视完全连接的层，卷积层以及注意力层的配方，并确认查询嵌入（即注意层内）在防止网络学习快捷键方面的重要作用。因此，我们提出了一个层的查询解码器，以帮助建模多级分布。其次，我们采用一个邻居掩盖的注意模块，以进一步避免从输入功能到重建的输出功能的信息泄漏。第三，我们提出了一种功能抖动策略，即使使用嘈杂的输入，也敦促模型恢复正确的消息。我们在MVTEC-AD和CIFAR-10数据集上评估了我们的算法，在该数据集中，我们通过足够大的利润率超过了最先进的替代方案。例如，当在MVTEC-AD中学习15个类别的统一模型时，我们在异常检测的任务（从88.1％到96.5％）和异常定位（从89.5％到96.8％）上超过了第二个竞争者。代码将公开可用。
