Using Artificial Intelligence to Protect Endangered Forest Elephants - Robot News
According to the National Academy of Sciences, a sixth mass extinction is underway. Animal species are disappearing at 1,000 to 10,000 times the natural rate. We recently reported on scientists using artificial intelligence to analyze photos to help track at-risk species such as giraffes and whale sharks. Now AI is being used to analyze sound to help protect forest elephants in central Africa. Mainly due to poachers and habitat destruction, the number of forest elephants went from an estimated 100,000 in 2011 to fewer than 40,000 today.

Trans-Sense: Real Time Transportation Schedule Estimation Using Smart Phones
AbdelAziz, Ali, Shoukry, Amin, Gomaa, Walid, Youssef, Moustafa
Developing countries suffer from traffic congestion, poorly planned road/rail networks, and lack of access to public transportation facilities. This context results in an increase in fuel consumption, pollution level, monetary losses, massive delays, and less productivity. On the other hand, it has a negative impact on the commuters feelings and moods. Availability of real-time transit information - by providing public transportation vehicles locations using GPS devices - helps in estimating a passenger's waiting time and addressing the above issues. However, such solution is expensive for developing countries. This paper aims at designing and implementing a crowd-sourced mobile phones-based solution to estimate the expected waiting time of a passenger in public transit systems, the prediction of the remaining time to get on/off a vehicle, and to construct a real time public transit schedule. Trans-Sense has been evaluated using real data collected for over 800 hours, on a daily basis, by different Android phones, and using different light rail transit lines at different time spans. The results show that Trans-Sense can achieve an average recall and precision of 95.35% and 90.1%, respectively, in discriminating lightrail stations. Moreover, the empirical distributions governing the different time delays affecting a passenger's total trip time enable predicting the right time of arrival of a passenger to her destination with an accuracy of 91.81%.In addition, the system estimates the stations dimensions with an accuracy of 95.71%.
Nonlinear System Identification via Tensor Completion
Kargas, Nikolaos, Sidiropoulos, Nicholas D.
Function approximation from input and output data pairs constitutes a fundamental problem in supervised learning. Deep neural networks are currently the most popular method for learning to mimic the input-output relationship of a generic nonlinear system, as they have proven to be very effective in approximating complex highly nonlinear functions. In this work, we propose low-rank tensor completion as an appealing alternative for modeling and learning complex nonlinear systems. We model the interactions between the $N$ input variables and the scalar output of a system by a single N-way tensor, and setup a weighted low-rank tensor completion problem with smoothness regularization which we tackle using a block coordinate descent algorithm. We extend our method to the multi-output setting and the case of partially observed data, which cannot be readily handled by neural networks. Finally, we demonstrate the effectiveness of the approach using several regression tasks including some standard benchmarks and a challenging student grade prediction task.
Cognitive Knowledge Graph Reasoning for One-shot Relational Learning
Du, Zhengxiao, Zhou, Chang, Ding, Ming, Yang, Hongxia, Tang, Jie
Inferring new facts from existing knowledge graphs (KG) with explainable reasoning processes is a significant problem and has received much attention recently. However, few studies have focused on relation types unseen in the original KG, given only one or a few instances for training. To bridge this gap, we propose CogKR for one-shot KG reasoning. The one-shot relational learning problem is tackled through two modules: the summary module summarizes the underlying relationship of the given instances, based on which the reasoning module infers the correct answers. Motivated by the dual process theory in cognitive science, in the reasoning module, a cognitive graph is built by iteratively coordinating retrieval (System 1, collecting relevant evidence intuitively) and reasoning (System 2, conducting relational reasoning over collected information). The structural information offered by the cognitive graph enables our model to aggregate pieces of evidence from multiple reasoning paths and explain the reasoning process graphically. Experiments show that CogKR substantially outperforms previous state-of-the-art models on one-shot KG reasoning benchmarks, with relative improvements of 24.3%-29.7% on MRR.

5 Key Learnings To Set-up A High Impact AI Strategy
In the following, I share the key learnings of the webinar. AI is not a secret sauce and requires lots of good data to create real value. Companies need to first separate the hype from the actual capabilities of AI, defining what AI means for them and how it might create value. Moving an entire company towards the adoption of AI is a challenging task and needs lots of educational effort. AI is not the solution to all problems. Building products do not start with thinking about AI but finding a meaningful problem that once solved adds value for the customer or user.
AI is worse at identifying household items from lower-income countries
Object recognition algorithms sold by tech companies, including Google, Microsoft, and Amazon, perform worse when asked to identify items from lower-income countries. These are the findings of a new study conducted by Facebook's AI lab, which shows that AI bias can not only reproduce inequalities within countries, but also between them. In the study (which we spotted via Jack Clark's Import AI newsletter), researchers tested five popular off-the-shelf object recognition algorithms -- Microsoft Azure, Clarifai, Google Cloud Vision, Amazon Rekognition, and IBM Watson -- to see how well each program identified household items collected from a global dataset. The dataset included 117 categories (everything from shoes to soap to sofas) and a diverse array of household incomes and geographic locations (from a family in Burundi making $27 a month to a family in Ukraine with a monthly income of $10,090). The researchers found that the object recognition algorithms made around 10 percent more errors when asked to identify items from a household with a $50 monthly income compared to those from a household making more than $3,500.
Learning Curves for Deep Neural Networks: A Gaussian Field Theory Perspective
Cohen, Omry, Malka, Or, Ringel, Zohar
A series of recent works suggest that deep neural networks (DNNs), of fixed depth, are equivalent to certain Gaussian Processes (NNGP/NTK) in the highly over-parameterized regime (width or number-of-channels going to infinity). Other works suggest that this limit is relevant for real-world DNNs. These results invite further study into the generalization properties of Gaussian Processes of the NNGP and NTK type. Here we make several contributions along this line. First, we develop a formalism, based on field theory tools, for calculating learning curves perturbatively in one over the dataset size. For the case of NNGPs, this formalism naturally extends to finite width corrections. Second, in cases where one can diagonalize the covariance-function of the NNGP/NTK, we provide analytic expressions for the asymptotic learning curves of any given target function. These go beyond the standard equivalence kernel results. Last, we provide closed analytic expressions for the eigenvalues of NNGP/NTK kernels of depth 2 fully-connected ReLU networks. For datasets on the hypersphere, the eigenfunctions of such kernels, at any depth, are hyperspherical harmonics. A simple coherent picture emerges wherein fully-connected DNNs have a strong entropic bias towards functions which are low order polynomials of the input.
