Oops! Predicting Unintentional Action in Video
From just a short glance at a video, we can often tell whether a person's
action is intentional or not. Can we train a model to recognize this? We
introduce a dataset of in-the-wild videos of unintentional action, as well as a
suite of tasks for recognizing, localizing, and anticipating its onset. We
train a supervised neural network as a baseline and analyze its performance
compared to human consistency on the tasks. We also investigate self-supervised
representations that leverage natural signals in our dataset, and show the
effectiveness of an approach that uses the intrinsic speed of video to perform
competitively with highly-supervised pretraining. However, a significant gap
between machine and human performance remains. The project website is available

Leveraging TCN and Transformer for effective visual-audio fusion in continuous emotion recognition
Human emotion recognition plays an important role in human-computer
interaction. In this paper, we present our approach to the Valence-Arousal (VA)
Estimation Challenge, Expression (Expr) Classification Challenge, and Action
Unit (AU) Detection Challenge of the 5th Workshop and Competition on Affective
Behavior Analysis in-the-wild (ABAW). Specifically, we propose a novel
multi-modal fusion model that leverages Temporal Convolutional Networks (TCN)
and Transformer to enhance the performance of continuous emotion recognition.
Our model aims to effectively integrate visual and audio information for
improved accuracy in recognizing emotions. Our model outperforms the baseline
and ranks 3 in the Expression Classification challenge.Comment: 2023 IEEE/CVF Conference on Computer Vision and Pattern Recognition

Wild Emptiness: A Zen Approach to Environmental Ethics
When Buddhism took root in China and integrated with the nation’s Taoist intellectual climate, the tradition retained the orthodox central objective of overcoming suffering. While conserving this principal aspiration, the rise of Zen is associated with deviation from the orthodox practice of monasticism and toward the practical embodiment of emptiness while integrated in society, which can be likened to the practice of unwavering compassion. This piece offers a Zen approach to environmental ethics such that it is an attempt to explicate how and why an individual practicing Zen should compassionately engage with the earth. With respect to the Buddhist employment of skillful means, different approaches are offered as tailored ethical frameworks to appeal to individuals at different stages in their path to awakening. Furthermore, the environmental ethic appealed to by the awakened individual is explicated as spontaneous harmonization with the flow of emptiness, that which the Buddhists regard to be the driving force of the phenomenal realm. The awakened individual is considered to non-deliberately take on a lifestyle that provides perpetual intimacy with the rhythms of wild emptines
Facial Expression Recognition from World Wild Web
Recognizing facial expression in a wild setting has remained a challenging
task in computer vision. The World Wide Web is a good source of facial images
which most of them are captured in uncontrolled conditions. In fact, the
Internet is a Word Wild Web of facial images with expressions. This paper
presents the results of a new study on collecting, annotating, and analyzing
wild facial expressions from the web. Three search engines were queried using
1250 emotion related keywords in six different languages and the retrieved
images were mapped by two annotators to six basic expressions and neutral. Deep
neural networks and noise modeling were used in three different training
scenarios to find how accurately facial expressions can be recognized when
trained on noisy images collected from the web using query terms (e.g. happy
face, laughing man, etc)? The results of our experiments show that deep neural
networks can recognize wild facial expressions with an accuracy of 82.12%
AVA: A Video Dataset of Spatio-temporally Localized Atomic Visual Actions
This paper introduces a video dataset of spatio-temporally localized Atomic
Visual Actions (AVA). The AVA dataset densely annotates 80 atomic visual
actions in 430 15-minute video clips, where actions are localized in space and
time, resulting in 1.58M action labels with multiple labels per person
occurring frequently. The key characteristics of our dataset are: (1) the
definition of atomic visual actions, rather than composite actions; (2) precise
spatio-temporal annotations with possibly multiple annotations for each person;
(3) exhaustive annotation of these atomic actions over 15-minute video clips;
(4) people temporally linked across consecutive segments; and (5) using movies
to gather a varied set of action representations. This departs from existing
datasets for spatio-temporal action recognition, which typically provide sparse
annotations for composite actions in short video clips. We will release the
dataset publicly.
AVA, with its realistic scene and action complexity, exposes the intrinsic
difficulty of action recognition. To benchmark this, we present a novel
approach for action localization that builds upon the current state-of-the-art
methods, and demonstrates better performance on JHMDB and UCF101-24 categories.
While setting a new state of the art on existing datasets, the overall results
on AVA are low at 15.6% mAP, underscoring the need for developing new
approaches for video understanding.Comment: To appear in CVPR 2018. Check dataset page

Beware the animals that dance: conservation as an unintended outcome of cultural practices
The International Union for the Conservation of Nature (IUCN) World Parks Congress of 2003 and the Conference of Parties to the Convention on Biological Diversity (CBD) of 2004 call for the recognition and support of Community Conserved Areas, with the CBD Programme of Work on Protected Areas committing countries to take action by 2008. Both within protected areas and in the matrix of land beyond reserves, customs and beliefs of indigenous and local communities can yield conservation benefits. Identifying an intention to conserve by the custodians of customary conserved areas can be challenging as customary practices are embedded within a myriad of cosmologies and worldviews. However, the definition of Community Conserved Areas does not require an expressed intention to conserve nor does it specify the mechanisms by which nature or natural resources can be conserved. Thus, conservation as an unintended outcome of cultural practices is included within the scope of community conservation. Fieldwork was conducted in Sabah, Malaysian Borneo, from October 2010 to April 2011. Data for the case study of Gumantong comes from an interview with Porodong Mogilin,!Native Chief Representative of Matunggong Native Court in Bavanggazo, Kudat and meetings of community leaders from the 13 villages surrounding Gumantong. This paper 1) employs the case study of Gumantong in Sabah, Malaysian Borneo, to highlight the distinction between communities expressing an intention to conserve and conservation as an unintended outcome of cultural practices and 2) considers the implications of this distinction for the process of recognizing and supporting Community Conserved Areas
