Inspired by the computational efficiency of human brain in processing unstructured data, neural networks have been explored since 1940s for a wide variety of data analytics applications. The latest generation of Deep Neural networks (DNNs) have achieved impressive successes rivaling typical human performance, thanks to their ability to capture hidden features from unstructured data using multiple layers of neurons [1]. However, as the number of layers (depth) of the networks increase, DNN training becomes computationally intense and time consuming due to the physically separated execution and memory units in conventional von Neumann machines. This has motivated the exploration of non-von Neumann architectures with closely integrated processing units and local memory elements in dense cross bar arrays with memristive devices [2]. It has been recently proposed that DNNs can be implemented by 2D cross bar arrays of resistive processing units (RPUs) that can store multiple analog states and adjust its conductivity with simple voltage pulses [3]. These RPU devices when implemented in a cross bar array can accelerate DNN training if all the weights in the array can be updated in parallel.

With an abundance of research papers in deep learning, reproducibility or adoption of the existing works becomes a challenge. This is due to the lack of open source implementations provided by the authors. Further, re-implementing research papers in a different library is a daunting task. To address these challenges, we propose a novel extensible approach, DLPaper2Code, to extract and understand deep learning design flow diagrams and tables available in a research paper and convert them to an abstract computational graph. The extracted computational graph is then converted into execution ready source code in both Keras and Caffe, in real-time. An arXiv-like website is created where the automatically generated designs is made publicly available for 5,000 research papers. The generated designs could be rated and edited using an intuitive drag-and-drop UI framework in a crowdsourced manner. To evaluate our approach, we create a simulated dataset with over 216,000 valid design visualizations using a manually defined grammar. Experiments on the simulated dataset show that the proposed framework provide more than $93\%$ accuracy in flow diagram content extraction.

Deep learning is the state-of-the-art in fields such as visual object recognition and speech recognition. This learning uses a large number of layers and a huge number of units and connections. Therefore, overfitting is a serious problem with it, and the dropout which is a kind of regularization tool is used. However, in online learning, the effect of dropout is not well known. This paper presents our investigation on the effect of dropout in online learning. We analyzed the effect of dropout on convergence speed near the singular point. Our results indicated that dropout is effective in online learning. Dropout tends to avoid the singular point for convergence speed near that point.

We review the problem of defining and inferring a "state" for a control system based on complex, high-dimensional, highly uncertain measurement streams such as videos. Such a state, or representation, should contain all and only the information needed for control, and discount nuisance variability in the data. It should also have finite complexity, ideally modulated depending on available resources. This representation is what we want to store in memory in lieu of the data, as it "separates" the control task from the measurement process. For the trivial case with no dynamics, a representation can be inferred by minimizing the Information Bottleneck Lagrangian in a function class realized by deep neural networks. The resulting representation has much higher dimension than the data, already in the millions, but it is smaller in the sense of information content, retaining only what is needed for the task. This process also yields representations that are invariant to nuisance factors and having maximally independent components. We extend these ideas to the dynamic case, where the representation is the posterior density of the task variable given the measurements up to the current time, which is in general much simpler than the prediction density maintained by the classical Bayesian filter. Again this can be finitely-parametrized using a deep neural network, and already some applications are beginning to emerge. No explicit assumption of Markovianity is needed; instead, complexity trades off approximation of an optimal representation, including the degree of Markovianity.

Computational paralinguistic analysis is increasingly being used in a wide range of applications, including security-sensitive applications such as speaker verification, deceptive speech detection, and medical diagnosis. While state-of-the-art machine learning techniques, such as deep neural networks, can provide robust and accurate speech analysis, they are susceptible to adversarial attacks. In this work, we propose a novel end-to-end scheme to generate adversarial examples by perturbing directly the raw waveform of an audio recording rather than specific acoustic features. Our experiments show that the proposed adversarial perturbation can lead to a significant performance drop of state-of-the-art deep neural networks, while only minimally impairing the audio quality.

We consider the task of semantic robotic grasping, in which a robot picks up an object of a user-specified class using only monocular images. Inspired by the two-stream hypothesis of visual reasoning, we present a semantic grasping framework that learns object detection, classification, and grasp planning in an end-to-end fashion. A "ventral stream" recognizes object class while a "dorsal stream" simultaneously interprets the geometric relationships necessary to execute successful grasps. We leverage the autonomous data collection capabilities of robots to obtain a large self-supervised dataset for training the dorsal stream, and use semi-supervised label propagation to train the ventral stream with only a modest amount of human supervision. We experimentally show that our approach improves upon grasping systems whose components are not learned end-to-end, including a baseline method that uses bounding box detection. Furthermore, we show that jointly training our model with auxiliary data consisting of non-semantic grasping data, as well as semantically labeled images without grasp actions, has the potential to substantially improve semantic grasping performance.

Yao Xin is Founder of PPLIVE and an alumnus of the 3rd CEIBS Entrepreneurial Leadership Camp. "Why is there so much discussion about artificial intelligence these days? I think it's likely because of last year's Man vs Machine battle between world Go champion Lee Sedol and Google DeepMind's artificial intelligence programme AlphaGo. In 1996 Chess Grandmaster Garry Kasparov won four out of a series of six chess matches played against the IBM supercomputer Deep Blue. What happened in the 20 years between these two events? What has caused today's big breakthroughs in artificial intelligence? I believe AlphaGo's victory is the result of a completely new deep learning algorithm. The rise of deep learning represents the beginning of the third wave of artificial intelligence, a revolution that has seen the learning and programming done by humans transformed into autonomous learning by machines, which is a significant change.
