Computational modeling of human multimodal language is an emerging research area in natural language processing spanning the language, visual and acoustic modalities. Comprehending multimodal language requires modeling not only the interactions within each modality (intra-modal interactions) but more importantly the interactions between modalities (cross-modal interactions). In this paper, we propose the Recurrent Multistage Fusion Network (RMFN) which decomposes the fusion problem into multiple stages, each of them focused on a subset of multimodal signals for specialized, effective fusion. Cross-modal interactions are modeled using this multistage fusion approach which builds upon intermediate representations of previous stages. Temporal and intra-modal interactions are modeled by integrating our proposed fusion approach with a system of recurrent neural networks. The RMFN displays state-of-the-art performance in modeling human multimodal language across three public datasets relating to multimodal sentiment analysis, emotion recognition, and speaker traits recognition. We provide visualizations to show that each stage of fusion focuses on a different subset of multimodal signals, learning increasingly discriminative multimodal representations.

Professor Phil Cohen, Director of the Laboratory for Dialogue Research, at Monash University, Faculty of Information Technology, will be a keynote speaker at the Digital A.I Summit, in Melbourne on August 28, 2018. He will discuss the strengths and weaknesses of current "conversational A.I" technology, which is used in today's digital assistants (e.g., Apple Computer's Siri, Google's Google Now, IBM's Watson, and Microsoft's Cortana, etc.), as well as for general classes of applications such as customer service. He will provide a way forward that promises to overcome their limitations to build systems that can participate in flexible, collaborative dialogues that help users to achieve their goals. The Digital A.I Summit is Australia's premier event for bringing together industry leaders and provides a collection of exclusive keynotes and expert panels explaining AI and how it is rapidly transforming many Australian workplaces to significantly improve their productivity. The Digital A.I Summit is a one-day conference and is run in conjunction with the Victorian Government's Digital Innovation Festival.

In this technical report, we present jLDADMM---an easy-to-use Java toolkit for conventional topic models. jLDADMM is released to provide alternatives for topic modeling on normal or short texts. It provides implementations of the Latent Dirichlet Allocation topic model and the one-topic-per-document Dirichlet Multinomial Mixture model (i.e. mixture of unigrams), using collapsed Gibbs sampling. In addition, jLDADMM supplies a document clustering evaluation to compare topic models. jLDADMM is open-source and available to download at: https://github.com/datquocnguyen/jLDADMM

Predictions about the billions of dollars that drone technology represents are as pervasive as they are extreme. Drone industry experts are currently tracking over 75 firms that offer drone market reports or forecasts of some type, all of which offer various opinions and numbers around what sort of an impact the technology will enable in industries like construction and agriculture as well as maritime and offshore services. It's easy and in some cases justified to get excited about the potential of the technology, but many of these predictions are based on how the drones might be utilized, as opposed to the difference they're actually making. It's why figuring out the ROI of UAVs is a key consideration when it comes to adoption, and it's why the current applications of drones in maritime and offshore services are so important to consider. The use cases of today are what will make some of those billion dollar predictions possible, and makes it essential to see these uses explored in depth and detail at industry events.

Machine learning and Big Data will produce the earliest wins for organizations utilizing emerging digital technology, according to Sehida Frawley, SAP Australia and New Zealand head of digital business services. However, she cautions, generating value and confidence in the technology will depend on an organization's resources, technology ecosystems, and trust. For example, in order for organizations to trust the outcome of machine learning, they must also be able to trust the underlying data, Frawley said. The trust requirement extends to other technology, like blockchain, where there must be "trust in the relationship of that chain." Ultimately, generating value from emerging technology like machine learning, blockchain, and IoT will also depend on resources – how much effort is required to have success – and the technology ecosystems to support new applications, Frawley said.

In addition to penning 37 plays, William Shakespeare was a prolific composer of sonnets -- crafting 154 of them during his life. Now, more than 400 years after his death, the Bard's words are influencing a new generation of poets. It's just that these writers do so with silicon imaginations and digital quills. A consortium of researchers from the University of Toronto, the University of Melbourne and IBM's Australia division have managed to teach a neural network to craft sonnets just as the Bard did in the 16th century, using his own words to teach the machine. They published their results at the 2018 ACL conference, and you can play around with the network itself over at GitHub.

These days having skills in deep learning and machine learning is one of the most trending things in the tech world right now, and businesses are looking to hire developers who possess good knowledge in machine learning. In fact, Java has become a usual norm for implementing new machine learning algorithms these days. There are so many benefits of learning Java and is accepted by the people in machine learning community, easy maintenance, marketability, and readability, among others. If you want to integrate machine learning into your existing Java business applications then you must hire Java developers for the same. In this post, we will list down some of the best libraries for implementing machine learning in existing Java applications.

Levin Kuhlmann, PhD, with Australia's University of Melbourne, said the team's evaluation revealed, on average, a 90 percent improvement in seizure prediction performance compared to previous results. Since the contest, researchers have developed the site Epilepsyecosystem.org, "Accurate seizure prediction will transform epilepsy management by offering early warnings to patients or triggering interventions," Kuhlmann said in the release. "Our results highlight the benefit of crowdsourcing an army of algorithms that can be trained for each patient and the best algorithm chosen for prospective, real-time seizure prediction. It's about bringing together the world's best data scientists and pooling the greatest algorithms to advance epilepsy research. The hope is to make seizures less like earthquakes, which can strike without warning, and more like hurricanes, where you have enough advance warning to seek safety."

The standard probabilistic perspective on machine learning gives rise to empirical risk-minimization tasks that are frequently solved by stochastic gradient descent (SGD) and variants thereof. We present a formulation of these tasks as classical inverse or filtering problems and, furthermore, we propose an efficient, gradient-free algorithm for finding a solution to these problems using ensemble Kalman inversion (EKI). Applications of our approach include offline and online supervised learning with deep neural networks, as well as graph-based semi-supervised learning. The essence of the EKI procedure is an ensemble based approximate gradient descent in which derivatives are replaced by differences from within the ensemble. We suggest several modifications to the basic method, derived from empirically successful heuristics developed in the context of SGD. Numerical results demonstrate wide applicability and robustness of the proposed algorithm.

Disregard for how the research could undermine the tribe's interests led to a lawsuit and out-of-court settlement. Science is a social enterprise. Many scientific programs interact with a wide range of communities and stakeholders to secure various types of access and permission, to seek cooperation and collaboration for scientific studies, to fulfill regulatory and ethical requirements, and to try to shape research strategies and to improve the translation of their findings into policy or practice. But these interactions are motivated disproportionately by the interests and goals of the scientific programs and less by the need to elicit and understand their implications for stakeholders. However, there is increasing recognition that substantive community and stakeholder engagement (CSE) can improve the performance, and even make or break the success, of some science programs by providing a means of navigating, and responding to, the complex social, economic, cultural, and political settings in which science programs are conducted.
