The Digitalisation of African Agriculture Report 2018-2019

An inclusive, digitally-enabled agricultural transformation could help achieve meaningful livelihood improvements for Africa’s smallholder farmers and pastoralists. It could drive greater engagement in agriculture from women and youth and create employment opportunities along the value chain. At CTA we staked a claim on this power of digitalisation to more systematically transform agriculture early on. Digitalisation, focusing on not individual ICTs but the application of these technologies to entire value chains, is a theme that cuts across all of our work. In youth entrepreneurship, we are fostering a new breed of young ICT ‘agripreneurs’. In climate-smart agriculture multiple projects provide information that can help towards building resilience for smallholder farmers. And in women empowerment we are supporting digital platforms to drive greater inclusion for women entrepreneurs in agricultural value chains

Imagining machine vision: Four visual registers from the Chinese AI industry

Machine vision is one of the main applications of artificial intelligence. In China, the machine vision industry makes up more than a third of the national AI market, and technologies like face recognition, object tracking and automated driving play a central role in surveillance systems and social governance projects relying on the large-scale collection and processing of sensor data. Like other novel articulations of technology and society, machine vision is defined, developed and explained by different actors through the work of imagination. In this article, we draw on the concept of sociotechnical imaginaries to understand how Chinese companies represent machine vision. Through a qualitative multimodal analysis of the corporate websites of leading industry players, we identify a cohesive sociotechnical imaginary of machine vision, and explain how four distinct visual registers contribute to its articulation. These four registers, which we call computational abstraction, human–machine coordination, smooth everyday, and dashboard realism, allow Chinese tech companies to articulate their global ambitions and competitiveness through narrow and opaque representations of machine vision technologies.publishedVersio

Uncertainty-Aware Workload Prediction in Cloud Computing

Predicting future resource demand in Cloud Computing is essential for managing Cloud data centres and guaranteeing customers a minimum Quality of Service (QoS) level. Modelling the uncertainty of future demand improves the quality of the prediction and reduces the waste due to overallocation. In this paper, we propose univariate and bivariate Bayesian deep learning models to predict the distribution of future resource demand and its uncertainty. We design different training scenarios to train these models, where each procedure is a different combination of pretraining and fine-tuning steps on multiple datasets configurations. We also compare the bivariate model to its univariate counterpart training with one or more datasets to investigate how different components affect the accuracy of the prediction and impact the QoS. Finally, we investigate whether our models have transfer learning capabilities. Extensive experiments show that pretraining with multiple datasets boosts performances while fine-tuning does not. Our models generalise well on related but unseen time series, proving transfer learning capabilities. Runtime performance analysis shows that the models are deployable in real-world applications. For this study, we preprocessed twelve datasets from real-world traces in a consistent and detailed way and made them available to facilitate the research in this field

Data-Driven Intelligent Scheduling For Long Running Workloads In Large-Scale Datacenters

Cloud computing is becoming a fundamental facility of society today. Large-scale public or private cloud datacenters spreading millions of servers, as a warehouse-scale computer, are supporting most business of Fortune-500 companies and serving billions of users around the world. Unfortunately, modern industry-wide average datacenter utilization is as low as 6% to 12%. Low utilization not only negatively impacts operational and capital components of cost efficiency, but also becomes the scaling bottleneck due to the limits of electricity delivered by nearby utility. It is critical and challenge to improve multi-resource efficiency for global datacenters. Additionally, with the great commercial success of diverse big data analytics services, enterprise datacenters are evolving to host heterogeneous computation workloads including online web services, batch processing, machine learning, streaming computing, interactive query and graph computation on shared clusters. Most of them are long-running workloads that leverage long-lived containers to execute tasks. We concluded datacenter resource scheduling works over last 15 years. Most previous works are designed to maximize the cluster efficiency for short-lived tasks in batch processing system like Hadoop. They are not suitable for modern long-running workloads of Microservices, Spark, Flink, Pregel, Storm or Tensorflow like systems. It is urgent to develop new effective scheduling and resource allocation approaches to improve efficiency in large-scale enterprise datacenters. In the dissertation, we are the first of works to define and identify the problems, challenges and scenarios of scheduling and resource management for diverse long-running workloads in modern datacenter. They rely on predictive scheduling techniques to perform reservation, auto-scaling, migration or rescheduling. It forces us to pursue and explore more intelligent scheduling techniques by adequate predictive knowledges. We innovatively specify what is intelligent scheduling, what abilities are necessary towards intelligent scheduling, how to leverage intelligent scheduling to transfer NP-hard online scheduling problems to resolvable offline scheduling issues. We designed and implemented an intelligent cloud datacenter scheduler, which automatically performs resource-to-performance modeling, predictive optimal reservation estimation, QoS (interference)-aware predictive scheduling to maximize resource efficiency of multi-dimensions (CPU, Memory, Network, Disk I/O), and strictly guarantee service level agreements (SLA) for long-running workloads. Finally, we introduced a large-scale co-location techniques of executing long-running and other workloads on the shared global datacenter infrastructure of Alibaba Group. It effectively improves cluster utilization from 10% to averagely 50%. It is far more complicated beyond scheduling that involves technique evolutions of IDC, network, physical datacenter topology, storage, server hardwares, operating systems and containerization. We demonstrate its effectiveness by analysis of newest Alibaba public cluster trace in 2017. We are the first of works to reveal the global view of scenarios, challenges and status in Alibaba large-scale global datacenters by data demonstration, including big promotion events like Double 11 . Data-driven intelligent scheduling methodologies and effective infrastructure co-location techniques are critical and necessary to pursue maximized multi-resource efficiency in modern large-scale datacenter, especially for long-running workloads

The Evolution of the Internet of Things Industry and Market in China: An Interplay of Institutions, Demands and Supply

This paper seeks to provide some explanation as to how demand-, supply- and institutions-related factors in China have affected the creation and diffusion of Internet of Things (IoT)-related products and services. Concerning demand side factors the paper demonstrates how potential market size and existing technology trajectory work in favor of IoT diffusion. As a related demand side factor the paper argues that, in terms of the technological trajectory, China has started farther from the frontier than most industrialized countries. The degree of incremental benefit from the IoT is thus higher in the country. As to the supply side factors, the article promotes an understanding of how Chinese technology companies have capitalized on a huge user base to develop IoT-based applications. It also suggests that technologies and expertise provided by foreign multinationals have also played crucial roles. Regarding formal institutions, the government's proactive policies have been a major factor in the IoT's evolution. It is also in the Chinese government's interest to develop IoT products to make censorship and surveillance more effective. Regarding informal institutions, Chinese consumers are less concerned than Westerners about being tracked and monitored, which provides a favorable condition for the adoption of IoT-enabled devices. Nonetheless, this condition is changing due to increasing abuse of consumer privacy. China and the U.S. are compared in terms of diffusion, key determinants, performance indicators and impacts of the IoT in order to understand the areas that China outperforms—and underperforms—the U.S. Some indicators are proposed to gauge the IoT-related performance and the impacts of the IoT

Digital ecosystems and super apps

Businesses are characterised by digital innovations, fusing the physical, artificial, and biological worlds, affecting societies, industries, and companies with ever-higher speed and intensity. There is no room for traditional strategic thinking in the process of a new world order with new competitive forces and increased uncertainty, where goals are continually changing, and resources must be flexibly reorganised. Established firms will be the losers with old management concepts, linear value chains, and rigid and closed organisational structures. This article explains why the banking industry is ripe for disruption. It introduces a conceptual framework based on a case study research of Chinese juggernauts with highly scalable data and value monetization based on platform business models and super-apps. Our journey from the industrial economy to the digital era opens up new vistas for creating and capturing value for businesses and clients of the next generation. We describe why modern leaders must embrace change, learn from Asia, and develop strategies through the lens of the ecosystem theory. Digital ecosystems focus on clients and data and consolidate goods and services from diverse sectors. We coined the holistic capability to bring together e-commerce, logistics, social media, and financial services as “The Golden Triangle of Digital Ecosystems” To achieve sustainable financial growth, we suggest an agile management approach that takes the digital transformation as a chance and builds upon partnerships to connect with diverse actors—technologically, socially, and culturally
