New AI tech reshapes skin cancer detection
Created by FotoFinder Systems, Moleanalyzer pro is a portal that lets physicians confirm their skin cancer diagnosis using evaluation techniques, combining specialist expertise with AI and including the option of receiving a second opinion from international skin cancer experts. FotoFinder Systems Global Brand Director Kathrin Niemela told HITNA that the technology aims to aid skin cancer diagnoses. According to the Cancer Council Australia, every year skin cancers account for around 80 per cent of all newly diagnosed cancers in Australia, with GPs seeing more than a million patients per year for skin cancer. In addition, the Australian Government identified that there were 14,320 new cases of melanoma skin cancer diagnosed in 2018, accounting for 10.4 per cent of all new cancer cases diagnosed. "The earlier skin cancer is detected, the better the prognosis. The leisure behaviour of sunbathing in many parts of the world makes early detection of skin cancer more important worldwide," Niemela said.

AI Dispatch - Vol II - 2nd February 2019, Saturday
It is the sign of the times to come, the impending fourth industrial revolution. AWS which is now almost about Machine Learning and hosts a variety of such services for every possible application, is being used by both public and private entities world over. Machine Learning is getting more and more pervasive, and the proof lies in the pudding and it is clear now, that pudding is selling like hot cake. This would be second re-invention of Amazon, which first launched AWS as primarily for cloud data services and is now a full-fledged automated cloud computing and machine learning integrated solution. The competitors, notably Microsoft would be surely watching closely.
A Meta-MDP Approach to Exploration for Lifelong Reinforcement Learning
Garcia, Francisco M., Thomas, Philip S.
In this paper we consider the problem of how a reinforcement learning agent that is tasked with solving a sequence of reinforcement learning problems (a sequence of Markov decision processes) can use knowledge acquired early in its lifetime to improve its ability to solve new problems. We argue that previous experience with similar problems can provide an agent with information about how it should explore when facing a new but related problem. We show that the search for an optimal exploration strategy can be formulated as a reinforcement learning problem itself and demonstrate that such strategy can leverage patterns found in the structure of related problems. We conclude with experiments that show the benefits of optimizing an exploration strategy using our proposed approach.
Generating Dialogue Agents via Automated Planning
Botea, Adi, Muise, Christian, Agarwal, Shubham, Alkan, Oznur, Bajgar, Ondrej, Daly, Elizabeth, Kishimoto, Akihiro, Lastras, Luis, Marinescu, Radu, Ondrej, Josef, Pedemonte, Pablo, Vodolan, Miroslav
Dialogue systems have many applications such as customer support or question answering. Typically they have been limited to shallow single turn interactions. However more advanced applications such as career coaching or planning a trip require a much more complex multi-turn dialogue. Current limitations of conversational systems have made it difficult to support applications that require personalization, customization and context dependent interactions. We tackle this challenging problem by using domain-independent AI planning to automatically create dialogue plans, customized to guide a dialogue towards achieving a given goal. The input includes a library of atomic dialogue actions, an initial state of the dialogue, and a goal. Dialogue plans are plugged into a dialogue system capable to orchestrate their execution. Use cases demonstrate the viability of the approach. Our work on dialogue planning has been integrated into a product, and it is in the process of being deployed into another.
Medical Diagnosis with a Novel SVM-CoDOA Based Hybrid Approach
Machine Learning is an important sub-field of the Artificial Intelligence and it has been become a very critical task to train Machine Learning techniques via effective method or techniques. Recently, researchers try to use alternative techniques to improve ability of Machine Learning techniques. Moving from the explanations, objective of this study is to introduce a novel SVM-CoDOA (Cognitive Development Optimization Algorithm trained Support Vector Machines) system for general medical diagnosis. In detail, the system consists of a SVM, which is trained by CoDOA, a newly developed optimization algorithm. As it is known, use of optimization algorithms is an essential task to train and improve Machine Learning techniques. In this sense, the study has provided a medical diagnosis oriented problem scope in order to show effectiveness of the SVM-CoDOA hybrid formation.
CodedPrivateML: A Fast and Privacy-Preserving Framework for Distributed Machine Learning
So, Jinhyun, Guler, Basak, Avestimehr, A. Salman, Mohassel, Payman
How to train a machine learning model while keeping the data private and secure? We present CodedPrivateML, a fast and scalable approach to this critical problem. CodedPrivateML keeps both the data and the model information-theoretically private, while allowing efficient parallelization of training across distributed workers. We characterize CodedPrivateML's privacy threshold and prove its convergence for logistic (and linear) regression. Furthermore, via experiments over Amazon EC2, we demonstrate that CodedPrivateML can provide an order of magnitude speedup (up to $\sim 34\times$) over the state-of-the-art cryptographic approaches.
China's research in artificial intelligence 'far outranks' Huawei threat, expert says
Experts are warning of the threat posed by China's use of artificial intelligence (AI) to develop a survellience state, and say the risk of such authoritarian behaviour spreading to other parts of the world is increasing. While Chinese technology company Huawei is making daily headlines at the moment, Greg Austin, professor of cyber security, strategy and diplomacy at the University of New South Wales, said there were more pressing concerns. "If I were asked which was the bigger threat from China to the West, is it Huawei or is it their research on artificial intelligence I would say it's their research on artificial intelligence," Professor Austin said. "That far outranks any of the concerns that we have from what Huawei might do in terms of foreign espionage." Huawei has been banned from taking part in the rollout of 5G mobile technology in Australia over national security concerns and has faced similar restrictions in other countries.
A Question Answering System Using Graph-Pattern Association Rules (QAGPAR) On YAGO Knowledge Base
Wahyudi, null, Khodra, Masayu Leylia, Prihatmanto, Ary Setijadi, Machbub, Carmadi
A question answering system (QA System) was developed that uses graph-pattern association rules on the YAGO knowledge base. The answer as output of the system is provided based on a user question as input. If the answer is missing or unavailable in the database, then graph-pattern association rules are used to get the answer. The architecture of this question answering system is as follows: question classification, graph component generation, query generation, and query processing. The question answering system uses association graph patterns in a waterfall model. In this paper, the architecture of the system is described, specifically discussing its reasoning and performance capabilities. The results of this research is that rules with high confidence and correct logic produce correct answers, and vice versa.
Decentralized Stochastic Optimization and Gossip Algorithms with Compressed Communication
Koloskova, Anastasia, Stich, Sebastian U., Jaggi, Martin
We consider decentralized stochastic optimization with the objective function (e.g. data samples for machine learning task) being distributed over $n$ machines that can only communicate to their neighbors on a fixed communication graph. To reduce the communication bottleneck, the nodes compress (e.g. quantize or sparsify) their model updates. We cover both unbiased and biased compression operators with quality denoted by $\omega \leq 1$ ($\omega=1$ meaning no compression). We (i) propose a novel gossip-based stochastic gradient descent algorithm, CHOCO-SGD, that converges at rate $\mathcal{O}\left(1/(nT) + 1/(T \delta^2 \omega)^2\right)$ for strongly convex objectives, where $T$ denotes the number of iterations and $\delta$ the eigengap of the connectivity matrix. Despite compression quality and network connectivity affecting the higher order terms, the first term in the rate, $\mathcal{O}(1/(nT))$, is the same as for the centralized baseline with exact communication. We (ii) present a novel gossip algorithm, CHOCO-GOSSIP, for the average consensus problem that converges in time $\mathcal{O}(1/(\delta^2\omega) \log (1/\epsilon))$ for accuracy $\epsilon > 0$. This is (up to our knowledge) the first gossip algorithm that supports arbitrary compressed messages for $\omega > 0$ and still exhibits linear convergence. We (iii) show in experiments that both of our algorithms do outperform the respective state-of-the-art baselines and CHOCO-SGD can reduce communication by at least two orders of magnitudes.
