Google In Working With AI In Africa Through These 6 Ways
The mission of Google’s first AI research center in Africa is to push the boundaries of AI while solving pressing problems affecting millions of people both locally and globally, like mapping buildings in remote locations to provide better electricity. The center was opened in 2018.
Here are six AI projects the Accra research center is working on and how they are hoping they’ll make a difference.
Mapping buildings
Even with satellite imagery, it can be difficult to map buildings in remote locations. When these buildings go unmapped, it can make things like planning infrastructure difficult. Our Open Buildings dataset project, launched by a team in the Accra research center, combines AI with satellite imagery to pinpoint the location of buildings. That helps governments and nonprofit organizations understand the needs of residents and offer assistance.
In Uganda, for example, the nonprofit Sunbird AI is using the dataset and working with the Ministry of Energy in Lamwo district to study villages’ electrification needs and plan potential solutions, such as prioritizing electricity in important areas like commercial centers. And we’re continuing to expand our Open Buildings dataset to see how it can help communities in more areas. In addition to various countries in Africa, the dataset now covers 16 countries in Southeast Asia, including Bangladesh and Thailand.
Forecasting floods
The United Nations has reported that half of the world’s least-developed countries lack adequate early warning systems for disasters, including floods. In West and Central Africa specifically, where flooding can be severe, early warning systems could enable better preparation and potential evacuation. Lifesaving technology, like our Flood Forecasting Initiative, can help residents stay safe and give governments time to prepare. We’re using AI models to predict when and where riverine floods will occur in 80 countries worldwide, including 23 in Africa. Our Flood Hub platform displays the forecasts up to seven days in advance, with detailed inundation maps — showing different water levels predicted in different areas — so people know what to expect where they live.
Predicting locusts
Locust infestations can have a devastating effect on food crops. Through collaborations with AI-product-focused company InstaDeep and the Food and Agriculture Organization (FAO) of the United Nations, our team at the Google AI center in Ghana is helping to better detect locust outbreaks and enable farmers to implement control measures. The AI center team is working on building a model that forecasts locust breeding grounds using historical data from the FAO and environmental variables like rainfall and temperature.
Improving maternal health outcomes with ultrasound
Ultrasounds can be crucial for identifying potential complications during pregnancy. In recent years, sensor technology has evolved to make ultrasound devices significantly more portable and affordable. Globally, we have been working on building AI models that can read ultrasound images and provide important information to healthcare workers. In Kenya, for instance, we are partnering with Jacaranda Health to help improve our ultrasound AI technology, with a focus on using handheld ultrasound devices that don’t need to be attached to larger machines. This can help people who aren’t trained to operate traditional ultrasound machines to acquire and interpret ultrasound images and triage high-risk patients, simply by sweeping the handheld probe across the mother’s belly.
Helping people with non-standard speech make their voices heard
We built Project Relate, an Android app that uses AI research, to help people with non-standard speech communicate more easily. After recording 500 phrases, users receive a personalized speech recognition model. Now available for user testing in Ghana, it can transcribe speech into the text; use a synthesized voice to repeat what the speaker has said; and engage Google Assistant to complete tasks, such as asking for directions, playing a song or turning on the lights.
Teaching reading to children worldwide
Due in part to the effects of COVID-19, it’s estimated that
