Optimizing Urban Critical Green Space Development Using Machine Learning
Ganjirad, Mohammad, Delavar, Mahmoud Reza, Bagheri, Hossein, Azizi, Mohammad Mehdi
This paper presents a novel framework for prioritizing urban green space development in Tehran using diverse socio-economic, environmental, and sensitivity indices. The indices were derived from various sources including Google Earth Engine, air pollution measurements, municipal reports and the Weather Research & Forecasting (WRF) model. The WRF model was used to estimate the air temperature at a 1 km resolution due to insufficient meteorological stations, yielding RMSE and MAE values of 0.96°C and 0.92°C, respectively. After data preparation, several machine learning models were used for binary vegetation cover classification including XGBoost, LightGBM, Random Forest (RF) and Extra Trees. RF achieved the highest performance, exceeding 94% in Overall Accuracy, Recall, and F1-score. Then, the probability of areas lacking vegetation cover was assessed using socio-economic, environmental and sensitivity indices. This resulted in the RF generating an urban green space development prioritization map. Feature Importance Analysis revealed that the most significant indices were nightly land surface temperature (LST) and sensitive population. Finally, the framework performance was validated through microclimate simulation to assess the critical areas after and before the green space development by green roofs. The simulation demonstrated reducing air temperature by up to 0.67°C after utilizing the green roof technology in critical areas. As a result, this framework provides a valuable tool for urban planners to develop green spaces.
Mitigating Vulnerable Road Users Occlusion Risk Via Collective Perception: An Empirical Analysis
Wolff, Vincent Albert, Xhoxhi, Edmir
Recent reports from the World Health Organization highlight that Vulnerable Road Users (VRUs) have been involved in over half of the road fatalities in recent years, with occlusion risk - a scenario where VRUs are hidden from drivers' view by obstacles like parked vehicles - being a critical contributing factor. To address this, we present a novel algorithm that quantifies occlusion risk based on the dynamics of both vehicles and VRUs. This algorithm has undergone testing and evaluation using a real-world dataset from German intersections. Additionally, we introduce the concept of Maximum Tracking Loss (MTL), which measures the longest consecutive duration a VRU remains untracked by any vehicle in a given scenario. Our study extends to examining the role of the Collective Perception Service (CPS) in VRU safety. CPS enhances safety by enabling vehicles to share sensor information, thereby potentially reducing occlusion risks. Our analysis reveals that a 25% market penetration of CPS-equipped vehicles can substantially diminish occlusion risks and significantly curtail MTL. These findings demonstrate how various scenarios pose different levels of risk to VRUs and how the deployment of Collective Perception can markedly improve their safety. Furthermore, they underline the efficacy of our proposed metrics to capture occlusion risk as a safety factor.
The Top 3 AI Myths in Cybersecurity
Whether it's in novels, or the movies based on them, artificial intelligence has been a subject of fascination for decades. The synthetic humans envisioned by Philip K. Dick remain (fortunately) the stuff of science fiction, artificial intelligence is real and playing an increasingly large role in many aspects of our lives. While it's fun to root against (or maybe for) human-like robots with AI brains, a much more mundane, but equally powerful form of AI is starting to play a role in cybersecurity. The goal is for AI to be a force multiplier for hardworking security professionals. Security operations center (SOC) analysts, as we saw in the most recent Devo SOC Performance Report, are often overwhelmed by the never-ending number of alerts that hit their screens each day.
MLOPS 101
ModelOps is a holistic strategy to move models through the analytics life cycle quickly and iteratively so they may be deployed faster and generate desired business value, whereas, MLOps is a set of approaches for delivering and maintaining machine learning models in production in a consistent and timely manner. ModelOps is essentially a superset of MLOps with enterprise features. Data science teams benefit from MLOps technologies, but there's still a gap between the teams designing and using AI and IT executives responsible for overseeing it. So, ModelOps comes into play, justifying its potential to be so game-changing. ML only provides value once models reach production.
India, US launch AI-focused forum to scale up science & technology relationship
Indo-US relationship in the field of Science & Technology is very old collaborations have resulted in great benefits for both the countries, he said adding that we need to further scale it up in various fields, and Artificial Intelligence (AI) can play a major role in the future. "We have identified the barriers for growth in India that could be useful for the United States too," Professor Sharma pointed. He also said that research, technology in artificial intelligence is being promoted and implemented in the country through a network of 25 technology hubs working as a triple helix set up under the National Mission on Interdisciplinary Cyber-Physical Systems. The initiative focuses on AI cooperation in critical areas that are priorities for both countries. Jonathan Margolis, Acting Deputy Assistant Secretary, U.S. Bureau of Oceans and International Environmental & Scientific Affairs, U.S. Department of State, said, "The US-India strategic partnership can be strengthened by focusing on AI cooperation in critical areas that are priorities for both countries."
Is your BI team AI ready? Enter AutoML 2.0
The notion of using data to predict future outcomes is far from new. Even highly technical products that performed "predictive analytics" analysis have already been available to enterprise organizations for many years. The notion of developing and deploying custom-built predictive solutions, however, have, for the most part, been the exclusive domain of Fortune 500 companies. The rarity of predictive analytics in the enterprise is mostly due to the technical complexity needed to create, train, and deploy the complex AI and Machine Learning (ML) models required to successfully develop predictive solutions. Over the past few years, the world of AI and ML development has seen rapid change.
Safety-Aware Hardening of 3D Object Detection Neural Network Systems
We study how state-of-the-art neural networks for 3D object detection using a single-stage pipeline can be made safety aware. We start with the safety specification (reflecting the capability of other components) that partitions the 3D input space by criticality, where the critical area employs a separate criterion on robustness under perturbation, quality of bounding boxes, and the tolerance over false negatives demonstrated on the training set. In the architecture design, we consider symbolic error propagation to allow feature-level perturbation. Subsequently, we introduce a specialized loss function reflecting (1) the safety specification, (2) the use of single-stage detection architecture, and finally, (3) the characterization of robustness under perturbation. We also replace the commonly seen non-max-suppression post-processing algorithm by a safety-aware non-max-inclusion algorithm, in order to maintain the safety claim created by the neural network. The concept is detailed by extending the state-of-the-art PIXOR detector which creates object bounding boxes in bird's eye view with inputs from point clouds.
113 enterprise AI companies you should know
Enterprise companies comprise a $3.4 trillion market worldwide of which an increasingly larger share is being allocated to artificial intelligence technologies. By our definition, "enterprise" technology companies create tools for workplace roles and functions that a large number of businesses use. For example, Salesforce is the primary enterprise software used by sales professionals in a company. Also known as a type of customer relationship management software, or CRM, it is the system of record for sales professionals to enter in their contacts, progress of leads, and for sales metrics to be tracked. Any company directly selling their products and services would benefit from a CRM.
