MultiIoT: Towards Large-scale Multisensory Learning for the Internet of Things
The Internet of Things (IoT), the network integrating billions of smart
physical devices embedded with sensors, software, and communication
technologies for the purpose of connecting and exchanging data with other
devices and systems, is a critical and rapidly expanding component of our
modern world. The IoT ecosystem provides a rich source of real-world modalities
such as motion, thermal, geolocation, imaging, depth, sensors, video, and audio
for prediction tasks involving the pose, gaze, activities, and gestures of
humans as well as the touch, contact, pose, 3D of physical objects. Machine
learning presents a rich opportunity to automatically process IoT data at
scale, enabling efficient inference for impact in understanding human
wellbeing, controlling physical devices, and interconnecting smart cities. To
develop machine learning technologies for IoT, this paper proposes MultiIoT,
the most expansive IoT benchmark to date, encompassing over 1.15 million
samples from 12 modalities and 8 tasks. MultiIoT introduces unique challenges
involving (1) learning from many sensory modalities, (2) fine-grained
interactions across long temporal ranges, and (3) extreme heterogeneity due to
unique structure and noise topologies in real-world sensors. We also release a
set of strong modeling baselines, spanning modality and task-specific methods
to multisensory and multitask models to encourage future research in
multisensory representation learning for IoT
Human Behaviour Recognition using Fuzzy System in Videos
Human behavior can be detected and analyzed using video sequence is a latest research topic in computer vision & machine learning. Human behavior is used as a basis for many modern applications, such as video surveillance, content-based information retrieval from videos etc. HBA (Human behaviour analysis) is tricky to design and develop due to uncertainty and ambiguity involved in people’s daily activities. To address this gap, we propose hierarchical structure combining TDNN, tracking algorithms, and fuzzy systems. As a result, HBA system performance will be improved in terms of robustness, effectiveness and scalability
Attentive monitoring of multiple video streams driven by a Bayesian foraging strategy
In this paper we shall consider the problem of deploying attention to subsets
of the video streams for collating the most relevant data and information of
interest related to a given task. We formalize this monitoring problem as a
foraging problem. We propose a probabilistic framework to model observer's
attentive behavior as the behavior of a forager. The forager, moment to moment,
focuses its attention on the most informative stream/camera, detects
interesting objects or activities, or switches to a more profitable stream. The
approach proposed here is suitable to be exploited for multi-stream video
summarization. Meanwhile, it can serve as a preliminary step for more
sophisticated video surveillance, e.g. activity and behavior analysis.
Experimental results achieved on the UCR Videoweb Activities Dataset, a
publicly available dataset, are presented to illustrate the utility of the
proposed technique.Comment: Accepted to IEEE Transactions on Image Processin
Dynamic Bayesian Collective Awareness Models for a Network of Ego-Things
A novel approach is proposed for multimodal collective awareness (CA) of multiple networked intelligent agents. Each agent is here considered as an Internet-of-Things (IoT) node equipped with machine learning capabilities; CA aims to provide the network with updated causal knowledge of the state of execution of actions of each node performing a joint task, with particular attention to anomalies that can arise. Data-driven dynamic Bayesian models learned from multisensory data recorded during the normal realization of a joint task (agent network experience) are used for distributed state estimation of agents and detection of abnormalities. A set of switching dynamic Bayesian network (DBN) models collectively learned in a training phase, each related to particular sensorial modality, is used to allow each agent in the network to perform synchronous estimation of possible abnormalities occurring when a new task of the same type is jointly performed. Collective DBN (CDBN) learning is performed by unsupervised clustering of generalized errors (GEs) obtained from a starting generalized model. A growing neural gas (GNG) algorithm is used as a basis to learn the discrete switching variables at the semantic level. Conditional probabilities linking nodes in the CDBN models are estimated using obtained clusters. CDBN models are associated with a Bayesian inference method, namely, distributed Markov jump particle filter (D-MJPF), employed for joint state estimation and abnormality detection. The effects of networking protocols and of communications in the estimation of state and abnormalities are analyzed. Performance is evaluated by using a small network of two autonomous vehicles performing joint navigation tasks in a controlled environment. In the proposed method, first the sharing of observations is considered in ideal condition, and then the effects of a wireless communication channel have been analyzed for the collective abnormality estimation of the agents. Rician wireless channel and the usage of two protocols (i.e., IEEE 802.11p and IEEE 802.15.4) along with different channel conditions are considered as well

Towards the internet of agents: an analysis of the internet of things from the intelligence and autonomy perspective
Recently, the scientific community has demonstrated a special interest in the process related to the integration of the agent-oriented
technology with Internet of Things (IoT) platforms. Then, it arises a novel approach named Internet of Agents (IoA) as an alternative
to add an intelligence and autonomy component for IoT devices and networks. This paper presents an analysis of the main benefits
derived from the use of the IoA approach, based on a practical point of view regarding the necessities that humans demand in their
daily life and work, which can be solved by IoT networks modeled as IoA infrastructures. It has been presented 24 study cases of the
IoA approach at different domains ––smart industry, smart city and smart health wellbeing–– in order to define the scope of these
proposals in terms of intelligence and autonomy in contrast to their corresponding generic IoT applications.En los Ăşltimos años, la comunidad cientĂfica ha mostrado un interĂ©s especial en torno al proceso de integraciĂłn de la tecnologĂa
