On Monday, the Pentagon announced the official adoption of a series of new principles for ethical use of artificial intelligence in warfare, the Associated Press reports. The principles were formed out of a commission with the (darkly Newspeak-y) name the Defense Innovation Board, which released its recommendations (title: "AI Principles: Recommendations on the Ethical Use of Artificial Intelligence by the Department of Defense") to the Pentagon last October. The board was fronted by former Google CEO Eric Schmidt, an interesting twist given (as pointed out by the AP) due to the way Google seemed to (or: pretended to) drop out of a defense department project involving A.I. in 2018 after internal protests from Google staffers (to say nothing of the way Google's involvement was handled by the Pentagon). The Next Web called the principles "hazy" and "toothless." And Dave Gershgorn of OneZero noted that these supposed ethics are missing "'don't kill somebody with a robot.'"

This week saw the return, for a third season, of the critically acclaimed HBO series Westworld. WW's central premise in its first 2 seasons was a theme park, sometime in the near future, populated by highly realistic robots or'hosts'. Human guests can pay exorbitant sums to interact with these robots, in a huge range of ways. In the'western' themed area – after which the show is named – guests can choose to be white-hatted heroes or black-hatted villains. The good guys get to be brave, chivalrous, honourable and generally decent.

In the world of AI and machine learning, it's common to hear fear-based statements in the media, or from your neighbors, about what the poor decisions unchecked algorithms might make -- everything from denying you credit to launching nuclear missiles. What most people rarely hear about are the actual challenges that cause AI practitioners to worry. At FICO World 2019 in New York, I sat down with Kate Crawford to discuss these kinds of problems with AI. Kate is a Distinguished Research Professor at NYU and a Principal Researcher at Microsoft Research, as well as the co-founder of AI Now. We found a lot of common ground as we explored data bias, untrained data scientists and other concerns.

Recent surveys, studies, forecasts and other quantitative assessments of the progress and impact of AI highlight the growing respect for data and its uses by businesses everywhere and the increasingly positive--but still mixed--attitudes towards AI by US consumers. The second wave of AI, right now, is soon going to fail because too much trickery and even self-trickery is used"--Simone Teufel, University of Cambridge "What's happening right now is not'AI.' That was an intellectual aspiration and that's still alive today as an aspiration… the dreams and aspirations are five hundred years from now--that's like the Greeks sitting there and saying it would be neat to get to the moon someday. We have no clue how the brain does computation"--Michael I. Jordan, University of California, Berkeley

The era of Machine Learning is here and it's making a lot of progress in the Technological field and according to a Gartner Report, Machine Learning and AI is going to create 2.3 million Jobs by 2020 and this massive growth has led to the evolution of various Machine Learning Tools that we will discuss in this article. Machine learning is a type of Artificial Intelligence that allows software applications to learn from the data and become more accurate in predicting outcomes without human intervention. Machine Learning is a concept which allows the machine to learn from examples and experience, and that too without being explicitly programmed. To make this happen we have a lot of Machine Learning Tools available today. Let's have a look at some of the most important and popular ones.

In real life, providing security for a set of large areas by covering the area with Unmanned Aerial Vehicles (UAVs) is a difficult problem that consist of multiple objectives. These difficulties are even greater if the area coverage must continue throughout a specific time window. We address this by considering a Vehicle Routing Problem with Time Windows (VRPTW) variation in which capacity of agents is one and each customer (target area) must be supplied with more than one vehicles simultaneously without violating time windows. In this problem, our aim is to find a way to cover all areas with the necessary number of UAVs during the time windows, minimize the total distance traveled, and provide a fast solution by satisfying the additional constraint that each agent has limited fuel. We present a novel algorithm that relies on clustering the target areas according to their time windows, and then incrementally generating transportation problems with each cluster and the ready UAVs. Then we solve transportation problems with the simplex algorithm to generate the solution. The performance of the proposed algorithm and other implemented algorithms to compare the solution quality is evaluated on example scenarios with practical problem sizes.

This paper presents unifying results for subspace identification (SID) and dynamic mode decomposition (DMD) for autonomous dynamical systems. We observe that SID seeks to solve an optimization problem to estimate an extended observability matrix and a state sequence that minimizes the prediction error for the state-space model. Moreover, we observe that DMD seeks to solve a rank-constrained matrix regression problem that minimizes the prediction error of an extended autoregressive model. We prove that existence conditions for perfect (error-free) state-space and low-rank extended autoregressive models are equivalent and that the SID and DMD optimization problems are equivalent. We exploit these results to propose a SID-DMD algorithm that delivers a provably optimal model and that is easy to implement. We demonstrate our developments using a case study that aims to build dynamical models directly from video data.

Coherent Gradients is a recently proposed hypothesis to explain why over-parameterized neural networks trained with gradient descent generalize well even though they have sufficient capacity to memorize the training set. Inspired by random forests, Coherent Gradients proposes that (Stochastic) Gradient Descent (SGD) finds common patterns amongst examples (if such common patterns exist) since descent directions that are common to many examples add up in the overall gradient, and thus the biggest changes to the network parameters are those that simultaneously help many examples. The original Coherent Gradients paper validated the theory through causal intervention experiments on shallow, fully connected networks on MNIST. In this work, we perform similar intervention experiments on more complex architectures (such as VGG, Inception and ResNet) on more complex datasets (such as CIFAR-10 and ImageNet). Our results are in good agreement with the small scale study in the original paper, thus providing the first validation of coherent gradients in more practically relevant settings. We also confirm in these settings that suppressing incoherent updates by natural modifications to SGD can significantly reduce overfitting--lending credence to the hypothesis that memorization occurs when few examples are responsible for most of the gradient used in the update. Furthermore, we use the coherent gradients theory to explore a new characterization of why some examples are learned earlier than other examples, i.e., "easy" and "hard" examples.
