IBM aims AI at Africa

Published

on

Artificial intelligence is seen as an advanced and dangerous technology, but IBM is showing how it can help solve problems for Africa, writes ARTHUR GOLDSTUCK.

Artificial intelligence has been getting a bad rap lately. It’s been blamed for the way Facebook and Twitter promote fake news on the basis of showing people more of what they are already click through to read. That in turn is credited by some with handing Donald Trump the US presidency. It’s also been blamed for introducing bias into anything from home loan approvals to facial recognition systems, which tend to be more accurate with Caucasian faces than those of others.

But a team of scientists at a research facility in Braamfontein, Johannesburg, hopes to change all that. 

“We are working on beneficial AI,” says Tapiwa  Chiwewe, a scientist at IBM Research, which opened its second global research lab in Africa at the Tshimologong precinct in 2016. “We want to create AI that benefits people. In Africa, there are all kinds of socio-economic problems and we’re in a unique position to create AI that improves people’s lives. But we also want to create economic and social value.”

The emphasis is not on AI for its own sake, or operating independently of humans, but on creating symbiotic systems that help humans perform their roles better.

“These range from data driven healthcare to digital urban ecosystems,” says Craig Holmes, vice president for Industry Solutions and Business Development at IBM Middle East and Africa. “We’re researching air-quality management in partnership with the city of Johannesburg and Tshwane, we’re looking at traffic management in cities, and even wildfire risk prediction in the Cape Town area.”

Many of these projects will deliver benefits in the medium- to long-term future, but at least one is ready to roll out. It will be launched this Sunday, April 22, marking Earth Day. Appropriately, it is aimed at promoting sustainable energy.

It’s called EmpowerSolar, and is a web-based application for designing solar powered solutions for domestic and business use. 

IBM explains on the site: “The app uses a sophisticated algorithm to determine an optimal solution, along with an estimated price based on current typical prices. The algorithm takes into account the amount of sunlight at your chosen location, along with the specified usage of the various electrical appliances chosen.”

The app was developed by Dr Ashley Gritzman, a young scientist at IBM Research. By coincidence, he had graduated as an electrical engineer and was an installer of solar systems before joining IBM. 

“I had a small startup, assessing people’s energy usage, monitoring household or small business consumption, and told them how to reduce their energy use, ranging from changing old light bulbs to LED, to using solar geysers for water heating. Then we’d spec the systems, and design and install. I saw there was a big divide between home owners who may want energy efficiency, and the knowledge of installers and retailers of the technology.

“When I joined this lab, they asked, what contribution can we make to the energy question in South Africa? I saw a big gap of information. For example, solar is regarded as way too expensive for many and they wouldn’t look at it. But in fact, people have no idea what it will cost. If they assume it will cost hundreds of thousands of rands, they won’t even pick up the phone to enquire. I wanted to bridge the gap between homeowners and new technology.”

Part of Gritzman’s motivation was the dramatic fall in solar costs: the price of panels has fallen 50% in the last 5 years. The Renewable Energy Independent Power Producer Procurement (REIPPP) programme, designed to encourage private investment in renewable energy, has seen contract prices fall from R4 to 65c per Kilowatt Hour since 2011.

“South Africa has great resources in both solar and wind, and there is no longer a question that it is cheaper than new-built coal or nuclear. But it has to be super user-friendly, so that my parents can use it; it has to be technically accurate and pricing has to be correct, or else it’s not useful. And the electrical designs it comes up with have to work and be correct.

“When I was doing the solar stuff myself, a design would take a lot of time and a lot of calculations to do an initial quote. Then they also want to run the garage lights, for example, and you have to redo it. The app will be useful to home owners, but also to installers to do a quick design and costing.”

Gritzman’s PhD was in machine learning and image processing, which fits in perfectly with the artificial intelligence focus of the Research Lab and IBM’s Watson AI engine, which has been used for numerous medical breakthroughs, ranging from cancer research to tuberculosis treatment. However, EmpowerSolar fed a personal passion, and he was quickly able to drive it from idea to reality.

“It’s a responsive web site, it looks like an app, but doesn’t have to be downloaded. You choose your location, and we ask a few questions that are easy to understand. The big difference is in how much sun you get.  We’ve got little sliders, and ask people to use those to select direction, angle of roof and appliances they’d like to use with solar energy.

“When I was an installer, we’d just say how many kilowatt hours do you use a month, and most people don’t know. So we build this from the ground up, with categories, like home office, kitchen, and lighting, and within each we have a database of generic appliances.”

Part of the purpose of the service is to promote energy-efficient behaviour. As users indicate the appliances they use, messages pop up that, for example, advise that an electric geyser uses a large amount of electricity, and indicates the cost and benefit of installing gas or solar. Nothing is hidden. The application includes costs for solar panels, batteries, charge controllers, inverters and installation costs.

Gritzman is as enthusiastic about South Africa’s advantages as he is about solar power.

“South Africa really is sunny. If you compare us with Germany, one of the world leaders in solar, the least sunny spot in South Africa still has more sun than the most sunny city in Germany. That puts in perspective what opportunity we have.”

SA startups in Visa final

Leading fintech companies from the Sub-Sahara Africa technology startup community have made it to the finals of Visa’s Everywhere Initiative.

Published

on

Among the 12 chosen, from the 238 total entries, South African startups Howler and FinChatBot will compete against innovators from across Sub Sahara Africa for a chance to secure funding of up to US$50,000 to develop their ideas when the initiative concludes in Johannesburg on July 24. 

Fintechs in Africa are making incredible strides; not only to bring more convenience to consumers, but also to enable people who would not otherwise have access to financial services or even a way to connect to the formal banking system. Venture funding for African startups jumped by 51% to $195 million in 2017 and fintech in Africa is expected to grow exponentially in the next few years as it continues to disrupt the traditional financial sector. With a clear goal of reducing reliance on cash, building digital payment based economies and increasing financial inclusion, Visa is committed to fostering an entrepreneurial spirit and driving innovation in its payments landscape. 

The Sub Saharan Africa edition of the Visa’s Everywhere Initiative challenged local fintech startup to deliver solutions based around three real life business challenges: 

  • How can startups leverage Visa Developer APIs to either:  Enable smaller merchants to accept payments in-store digitally OR Provide a safe and secure solution for online merchants to drive eCommerce and reduce cash on delivery?
  • How can startups use Visa’s APIs to leverage mass reach and social media partner platforms like Facebook to help businesses operating in fast-paced consumer centric environments improve cash flow and receive payments? 
  • How can startups leverage technology to provide services that are functional for illiterate customers to provide them with secure transaction experiences that build and enhance their confidence in the banking system?. 

Entrants were asked to submit ideas to leverage Visa’s network and technologies to resolve against at least one of the challenges. One winner per brief will be selected, with each receiving funding of US$25,000. Winners will be invited to a working meeting with Visa and may be presented with the opportunity to create a prototype. Visa will then select one overall winner to receive an additional US$25,000.

Geraldine Mitchley, Senior Director – Digital Solutions, Sub-Sahara Africa, Visa, said: “We are delighted with the response to our Visa’s Everywhere Initiative and the quality of submissions we received is an indication of the region’s rich talent pool and innovative spirit.”

“Launching this innovation program in the region has been an exciting time for the Visa SSA team, and the takeup reflects Africa’s enthusiasm to develop and pioneer solutions to the continent’s challenge – particularly in the payments technology space. I would like to congratulate the finalists and  wish them luck as they enter the final stretch.  When they come together for the final, they will not only have the chance to turn their ideas into reality, but also potentially help shape the future of payments in the region.”  

Howler which enables cashless transactions and end-to-end ticket handling for consumers and event organisers is competing in the first challenge and FinChatBot, which aims to automate part of customer services for financial service providers through AI-powered conversations is competing in the third challenge. 

The SSA edition of the Visa’s Everywhere Initiative will wrap up on July 24 in Johannesburg, with each finalist having an opportunity to pitch their ideas to a panel of expert judges from Visa and the payments industry.

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entries via Twitter, so please don’t enter through the comments section of this article.)

2. Tell us on Twitter, via @GadgetZA, mentioning @Takealot in your posting, how many Watts the Poster Heater consumes.

cleardot.gif3. The competition closes on 31 July 2018.

4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.

5. The competition is only open to South African residents.
