了解全文学术文章的关键见解至关重要，因为它使我们能够确定有趣的趋势，洞悉研究和发展，并构建知识图。但是，只有在考虑全文时才可用一些有趣的关键见解。尽管研究人员在简短文档中的信息提取方面取得了重大进展，但从全文学术文献中提取科学实体仍然是一个具有挑战性的问题。这项工作提出了一种称为ENEREX的自动端对端研究实体提取器，用于提取技术集，客观任务，全文学术学术研究文章等技术方面。此外，我们提取了三个新颖的方面，例如源代码，计算资源，编程语言/库中的链接。我们演示了Enerex如何从计算机科学领域的大规模数据集中提取关键见解和趋势。我们进一步测试了多个数据集上的管道，发现ENEREX在最新模型的状态下进行了改进。我们强调了现有数据集的能力如何受到限制，以及enerex如何适应现有知识图。我们还向未来研究的指针进行了详细的讨论。我们的代码和数据可在https://github.com/discoveryanalyticscenter/enerex上公开获取。

端到端（E2E）模型已成为最新语音识别系统的默认选择。此类型号经过大量标记数据的培训，这些数据通常无法用于低资源语言。诸如自我监督学习和转移学习的诺言之类的技术尚未在培训准确的模型中有效。另一方面，在各种域和扬声器集合上收集标记的数据集非常昂贵。在这项工作中，我们通过公共资料中的印度语言，特别是来自印度广播电台的公共档案馆的印度语言的``采矿''文本和音频对展示了这些方法的廉价和有效替代方案。作为关键组件，我们将Needleman-Wunsch算法调整为与相应的音频片段对齐句子，并给定长音频和其转录本的PDF，同时由于OCR，无关紧要的文本和未转录的语音而对错误进行了强大的态度。因此，我们创建了Shrutilipi，这是一个数据集，其中包含超过6,400个小时的12个印度语言标签的音频，总计为495万个句子。平均而言，Shrutilipi导致2.3倍增加了公开可用的标签数据。我们在12种语言中与21种人类评估者建立了Shrutilipi的质量。我们还根据代表区域，说话者和提到的实体建立了Shrutilipi的多样性。值得注意的是，我们表明，将Shrutilipi添加到WAV2VEC模型的训练集中，导致在Indicsuperb基准上的7种语言中，平均降低了5.8 \％。对于具有最多基准的印地语（7），平均水平从18.8％下降到13.5％。这种改进扩展到有效的模型：对于构象异构体模型（比WAV2VEC小10倍），我们显示出2.3％的下降。最后，我们通过证明对其进行训练的模型对嘈杂的输入更强大，证明了Shrutilipi的多样性。

AI研究中的基石是创建和采用标准化培训和测试数据集，以指定最新模型的进度。一个特别成功的例子是用于培训和评估英语自然语言理解（NLU）模型的胶水数据集。围绕基于BERT的语言模型的大量研究围绕着胶水中NLU任务的性能改进。为了评估其他语言的语言模型，创建了几个特定语言的胶水数据集。语音语言理解（SLU）的领域遵循了类似的轨迹。大型自我监督模型（例如WAV2VEC2）的成功实现了具有相对易于访问的未标记数据的语音模型。然后可以在SLU任务（例如出色的基准测试）上评估这些模型。在这项工作中，我们将其扩展到通过释放Indicsuperb基准测试来指示语言。具体来说，我们做出以下三项贡献。 （i）我们收集了Kathbath，其中包含来自印度203个地区的1,218个贡献者的12个印度语言的1,684小时的标记语音数据。 （ii）使用Kathbath，我们在6个语音任务中创建基准：自动语音识别，扬声器验证，说话者识别（单声道/多），语言识别，逐个示例查询以及对12种语言的关键字发现。 （iii）在发布的基准测试中，我们与常用的基线Fbank一起训练和评估不同的自我监督模型。我们表明，在大多数任务上，特定于语言的微调模型比基线更准确，包括对于语言识别任务的76 \％差距。但是，对于说话者识别，在大型数据集上训练的自我监督模型证明了一个优势。我们希望Indicsuperb有助于发展印度语言的语音语言理解模型的进步。

最近的言语和语言技术的方法预先rain非常大型模型，用于特定任务。然而，这种大型模型的好处通常仅限于世界上少数资源丰富的语言。在这项工作中，我们对来自印度次大陆的低资源语言构建ASR系统进行多种贡献。首先，我们从各种领域策划40个印度语言的17,000小时的原始语音数据，包括教育，新闻，技术和金融。其次，使用这种原始语音数据，我们预先存在于40个印度语言的Wav2Vec样式模型的多个变体。第三，我们分析佩带的模型以查找关键特点：码本矢量的类似探测音素在语言中共享，跨层的表示是语言系列的判别，并且注意力头通常会在小型本地窗口中注意。第四，我们微调了9种语言的下游ASR模型，并在3个公共数据集上获得最先进的结果，包括非常低的资源语言，如Sinhala和Nepali。我们的工作建立了多语言预介质是建立ASR系统的有效策略，为印度次大陆的语言上不同的扬声器建立ASR系统。

Quadruped robots are currently used in industrial robotics as mechanical aid to automate several routine tasks. However, presently, the usage of such a robot in a domestic setting is still very much a part of the research. This paper discusses the understanding and virtual simulation of such a robot capable of detecting and understanding human emotions, generating its gait, and responding via sounds and expression on a screen. To this end, we use a combination of reinforcement learning and software engineering concepts to simulate a quadruped robot that can understand emotions, navigate through various terrains and detect sound sources, and respond to emotions using audio-visual feedback. This paper aims to establish the framework of simulating a quadruped robot that is emotionally intelligent and can primarily respond to audio-visual stimuli using motor or audio response. The emotion detection from the speech was not as performant as ERANNs or Zeta Policy learning, still managing an accuracy of 63.5%. The video emotion detection system produced results that are almost at par with the state of the art, with an accuracy of 99.66%. Due to its "on-policy" learning process, the PPO algorithm was extremely rapid to learn, allowing the simulated dog to demonstrate a remarkably seamless gait across the different cadences and variations. This enabled the quadruped robot to respond to generated stimuli, allowing us to conclude that it functions as predicted and satisfies the aim of this work.

Searching long egocentric videos with natural language queries (NLQ) has compelling applications in augmented reality and robotics, where a fluid index into everything that a person (agent) has seen before could augment human memory and surface relevant information on demand. However, the structured nature of the learning problem (free-form text query inputs, localized video temporal window outputs) and its needle-in-a-haystack nature makes it both technically challenging and expensive to supervise. We introduce Narrations-as-Queries (NaQ), a data augmentation strategy that transforms standard video-text narrations into training data for a video query localization model. Validating our idea on the Ego4D benchmark, we find it has tremendous impact in practice. NaQ improves multiple top models by substantial margins (even doubling their accuracy), and yields the very best results to date on the Ego4D NLQ challenge, soundly outperforming all challenge winners in the CVPR and ECCV 2022 competitions and topping the current public leaderboard. Beyond achieving the state-of-the-art for NLQ, we also demonstrate unique properties of our approach such as gains on long-tail object queries, and the ability to perform zero-shot and few-shot NLQ.

Machine Translation (MT) system generally aims at automatic representation of source language into target language retaining the originality of context using various Natural Language Processing (NLP) techniques. Among various NLP methods, Statistical Machine Translation(SMT). SMT uses probabilistic and statistical techniques to analyze information and conversion. This paper canvasses about the development of bilingual SMT models for translating English to fifteen low-resource Indian Languages (ILs) and vice versa. At the outset, all 15 languages are briefed with a short description related to our experimental need. Further, a detailed analysis of Samanantar and OPUS dataset for model building, along with standard benchmark dataset (Flores-200) for fine-tuning and testing, is done as a part of our experiment. Different preprocessing approaches are proposed in this paper to handle the noise of the dataset. To create the system, MOSES open-source SMT toolkit is explored. Distance reordering is utilized with the aim to understand the rules of grammar and context-dependent adjustments through a phrase reordering categorization framework. In our experiment, the quality of the translation is evaluated using standard metrics such as BLEU, METEOR, and RIBES

We introduce Argoverse 2 (AV2) - a collection of three datasets for perception and forecasting research in the self-driving domain. The annotated Sensor Dataset contains 1,000 sequences of multimodal data, encompassing high-resolution imagery from seven ring cameras, and two stereo cameras in addition to lidar point clouds, and 6-DOF map-aligned pose. Sequences contain 3D cuboid annotations for 26 object categories, all of which are sufficiently-sampled to support training and evaluation of 3D perception models. The Lidar Dataset contains 20,000 sequences of unlabeled lidar point clouds and map-aligned pose. This dataset is the largest ever collection of lidar sensor data and supports self-supervised learning and the emerging task of point cloud forecasting. Finally, the Motion Forecasting Dataset contains 250,000 scenarios mined for interesting and challenging interactions between the autonomous vehicle and other actors in each local scene. Models are tasked with the prediction of future motion for "scored actors" in each scenario and are provided with track histories that capture object location, heading, velocity, and category. In all three datasets, each scenario contains its own HD Map with 3D lane and crosswalk geometry - sourced from data captured in six distinct cities. We believe these datasets will support new and existing machine learning research problems in ways that existing datasets do not. All datasets are released under the CC BY-NC-SA 4.0 license.

Cashews are grown by over 3 million smallholders in more than 40 countries worldwide as a principal source of income. As the third largest cashew producer in Africa, Benin has nearly 200,000 smallholder cashew growers contributing 15% of the country's national export earnings. However, a lack of information on where and how cashew trees grow across the country hinders decision-making that could support increased cashew production and poverty alleviation. By leveraging 2.4-m Planet Basemaps and 0.5-m aerial imagery, newly developed deep learning algorithms, and large-scale ground truth datasets, we successfully produced the first national map of cashew in Benin and characterized the expansion of cashew plantations between 2015 and 2021. In particular, we developed a SpatioTemporal Classification with Attention (STCA) model to map the distribution of cashew plantations, which can fully capture texture information from discriminative time steps during a growing season. We further developed a Clustering Augmented Self-supervised Temporal Classification (CASTC) model to distinguish high-density versus low-density cashew plantations by automatic feature extraction and optimized clustering. Results show that the STCA model has an overall accuracy of 80% and the CASTC model achieved an overall accuracy of 77.9%. We found that the cashew area in Benin has doubled from 2015 to 2021 with 60% of new plantation development coming from cropland or fallow land, while encroachment of cashew plantations into protected areas has increased by 70%. Only half of cashew plantations were high-density in 2021, suggesting high potential for intensification. Our study illustrates the power of combining high-resolution remote sensing imagery and state-of-the-art deep learning algorithms to better understand tree crops in the heterogeneous smallholder landscape.

We propose an ensemble approach to predict the labels in linear programming word problems. The entity identification and the meaning representation are two types of tasks to be solved in the NL4Opt competition. We propose the ensembleCRF method to identify the named entities for the first task. We found that single models didn't improve for the given task in our analysis. A set of prediction models predict the entities. The generated results are combined to form a consensus result in the ensembleCRF method. We present an ensemble text generator to produce the representation sentences for the second task. We thought of dividing the problem into multiple small tasks due to the overflow in the output. A single model generates different representations based on the prompt. All the generated text is combined to form an ensemble and produce a mathematical meaning of a linear programming problem.
