Introducing MissingLink: Streamlining the Entire Deep Learning Lifecycle -
Today we're excited to announce the public launch of MissingLink.ai to help data scientists and engineers streamline and automate the entire deep learning cycle. With this launch, we hope to eliminate a lot of the grunt work associated with machine learning and to accelerate the time it takes to train and deliver effective models. Work on MissingLink began in 2016, when my colleagues Shay Erlichmen, Rahav Lussato, and I set out to solve a problem we experienced as software engineers. While working on deep learning projects at our previous company, we realized we were spending too much time managing the sheer volume of data we were collecting and analyzing, and too little time learning from it. We also realized we weren't alone.

How AI Can Help Employers Overcome The Demographic Crunch
SAN FRANCISCO โ Of all the challenges I face as a CEO, nothing is more critical than attracting and retaining talented people. Declining birth rates are starting to deplete the global labor pool. This problem is particularly acute in Japan, China, South Korea, and most of Western Europe, which have "sub-replacement" birth rates--that is, the number of children born is below the level needed to sustain population and ultimately employment levels. It's also becoming a major concern in the United States, especially as the country's declining high-school graduation rate and soaring college costs narrow the supply of highly skilled, highly technical people. As companies worldwide compete for ever-scarcer human resources, we're going to have to get much better at identifying, attracting, evaluating, and retaining the best people.
On Human Robot Interaction using Multiple Modes
Humanoid robots have apparently similar body structure like human beings. Due to their technical design, they are sharing the same workspace with humans. They are placed to clean things, to assist old age people, to entertain us and most importantly to serve us. To be acceptable in the household, they must have higher level of intelligence than industrial robots and they must be social and capable of interacting people around it, who are not supposed to be robot specialist. All these come under the field of human robot interaction (HRI). There are various modes like speech, gesture, behavior etc. through which human can interact with robots. To solve all these challenges, a multimodel technique has been introduced where gesture as well as speech is used as a mode of interaction.
Monotonic classification: an overview on algorithms, performance measures and data sets
Cano, Josรฉ-Ramรณn, Gutiรฉrrez, Pedro Antonio, Krawczyk, Bartosz, Woลบniak, Michaล, Garcรญa, Salvador
Currently, knowledge discovery in databases is an essential step to identify valid, novel and useful patterns for decision making. There are many real-world scenarios, such as bankruptcy prediction, option pricing or medical diagnosis, where the classification models to be learned need to fulfil restrictions of monotonicity (i.e. the target class label should not decrease when input attributes values increase). For instance, it is rational to assume that a higher debt ratio of a company should never result in a lower level of bankruptcy risk. Consequently, there is a growing interest from the data mining research community concerning monotonic predictive models. This paper aims to present an overview about the literature in the field, analyzing existing techniques and proposing a taxonomy of the algorithms based on the type of model generated. For each method, we review the quality metrics considered in the evaluation and the different data sets and monotonic problems used in the analysis. In this way, this paper serves as an overview of the research about monotonic classification in specialized literature and can be used as a functional guide of the field.
Incentivizing the Dynamic Workforce: Learning Contracts in the Gig-Economy
Cohen, Alon, Koren, Moran, Deligkas, Argyrios
In principal-agent models, a principal offers a contract to an agent to perform a certain task. The agent exerts a level of effort that maximizes her utility. The principal is oblivious to the agent's chosen level of effort, and conditions her wage only on possible outcomes. In this work, we consider a model in which the principal is unaware of the agent's utility and action space. She sequentially offers contracts to identical agents, and observes the resulting outcomes. We present an algorithm for learning the optimal contract under mild assumptions. We bound the number of samples needed for the principal obtain a contract that is within $\epsilon$ of her optimal net profit for every $\epsilon>0$.
Reliable counting of weakly labeled concepts by a single spiking neuron model
Rapp, Hannes, Nawrot, Martin Paul, Stern, Merav
Making an informed, correct and quick decision can be life-saving. It's crucial for animals during an escape behaviour or for autonomous cars during driving. The decision can be complex and may involve an assessment of the amount of threats present and the nature of each threat. Thus, we should expect early sensory processing to supply classification information fast and accurately, even before relying the information to higher brain areas or more complex system components downstream. Today, advanced convolutional artificial neural networks can successfully solve visual detection and classification tasks and are commonly used to build complex decision making systems. However, in order to perform well on these tasks they require increasingly complex, "very deep" model structure, which is costly in inference run-time, energy consumption and number of training samples, only trainable on cloud-computing clusters. A single spiking neuron has been shown to be able to solve recognition tasks for homogeneous Poisson input statistics, a commonly used model for spiking activity in the neocortex. When modeled as leaky integrate and fire with gradient decent learning algorithm it was shown to posses a variety of complex computational capabilities. Here we improve its implementation. We also account for more natural stimulus generated inputs that deviate from this homogeneous Poisson spiking. The improved gradient-based local learning rule allows for significantly better and stable generalization. We also show that with its improved capabilities it can count weakly labeled concepts by applying our model to a problem of multiple instance learning (MIL) with counting where labels are only available for collections of concepts. In this counting MNIST task the neuron exploits the improved implementation and outperforms conventional ConvNet architecture under similar condtions.
On Training Recurrent Neural Networks for Lifelong Learning
Sodhani, Shagun, Chandar, Sarath, Bengio, Yoshua
Lifelong Machine Learning considers systems that can learn many tasks (from one or more domains) over a lifetime (Thrun, 1998; Silver et al., 2013). This has several names and manifestations in the literature: incremental learning (Solomonoff, 1989), continual learning (Ring, 1997), explanation-based learning (Thrun, 1996, 2012), never ending learning (Carlson et al., 2010), etc. The underlying idea motivating these efforts is the following: Lifelong learning systems would be more effective at learning and retaining knowledge across different tasks. By using the prior knowledge and exploiting similarity acrosstasks, they would be able to obtain better priors for the task at hand. Lifelong learning techniques are very important for training intelligent autonomous agents that would need to operate and make decisions over extended periods of time. These characteristics arespecially important in the industrial setups where the deployed machine learning models are being updated frequently with new incoming data whose distribution neednot match the data on which the model was originally trained. Lifelong learning is an extremely challenging task for the machine learning models because of two primary reasons: 1. Catastrophic Forgetting: As the model is trained on a new task (or a new data/task distribution), it is likely to forget the knowledge it acquired from the previous tasks (or data distributions). This phenomenon is also known as the catastrophic interference (McCloskey and Cohen, 1989).
Machine Decisions and Human Consequences
Scantamburlo, Teresa, Charlesworth, Andrew, Cristianini, Nello
As we increasingly delegate decision-making to algorithms, whether directly or indirectly, important questions emerge in circumstances where those decisions have direct consequences for individual rights and personal opportunities, as well as for the collective good. A key problem for policymakers is that the social implications of these new methods can only be grasped if there is an adequate comprehension of their general technical underpinnings. The discussion here focuses primarily on the case of enforcement decisions in the criminal justice system, but draws on similar situations emerging from other algorithms utilised in controlling access to opportunities, to explain how machine learning works and, as a result, how decisions are made by modern intelligent algorithms or 'classifiers'. It examines the key aspects of the performance of classifiers, including how classifiers learn, the fact that they operate on the basis of correlation rather than causation, and that the term 'bias' in machine learning has a different meaning to common usage.An example of a real world 'classifier', the Harm Assessment Risk Tool (HART), is examined, through identification of its technical features: the classification method, the training data and the test data, the features and the labels, validation and performance measures. Four normative benchmarks are then considered by reference to HART: (a) prediction accuracy (b) fairness and equality before the law (c) transparency and accountability (d) informational privacy and freedom of expression, in order to demonstrate how its technical features have important normative dimensions that bear directly on the extent to which the system can be regarded as a viable and legitimate support for, or even alternative to, existing human decision-makers.
Google Program Offers Funding for AI, Machine Learning Projects -- THE Journal
A "smart" wildfire sensor developed by two high school students in Cupertino, CA (Photo: Google) Google has set aside $25 million to fund research work by schools and other organizations using machine learning for "social good." Besides cash, the company's "AI for Social Good" project is also offering support from its artificial intelligence experts, credits and consulting from Google Cloud. Those chosen will also join a "launchpad" accelerator program with mentoring, support and access to Silicon Valley experts. Projects seeking funding need to address a societal challenge and have a clear plan to deploy the AI model for real-world impact. Organizations will have until the end of January 21, 2019 to submit their applications.
