WHAT IS ARTIFICIAL INTELLIGENCE
Artificial intelligence (AI) is, as its name suggests, a form of intelligence that mimics the natural, human thought processes, but is displayed by machines, particularly by computer systems. Expressions of this intelligence are, for example, learning, problem solving, & self-correction.
Machine learning is an application of AI and refers to a computer’s ability to learn without being explicitly programmed.
WHO IS IT FOR
AI has a great potential to assist humans in many tasks, both simple and challenging ones. Its applications can, and already are serving, healthcare, transportation, & finance.
WHY IS IT NEEDED
WHAT ARE WE DOING
We nowadays have access to multiple digital sources and tools that can inform on what’s happening at a particular location. For example, we can use social media (Facebook, Twitter), websites, maps, satellite images and collaborative maps such as OSM to focus on a specific area.
We have been using AI models for the following purposes:
1. To get a better image of the situation on the ground
Timeliness is of utmost importance during a disaster. In the event of a disaster or crises an AI model can assist us in two ways:
- To identify which buildings are affected
- To assess physical damage of those buildings
2. To make better, more informed decisions, faster
AI models can return an assessment of damage after a disaster, identifying areas with no visible damage, and areas with partial, complete or extensive damage. We share this data with humanitarian workers on the ground so that they can better organize and prioritize their response.
3. To predict disasters and intervene before the damage is done
Data from previous disasters can be used to create machine learning models to predict damage during future such events. Thus, it becomes possible to prepare and reduce the impact of a disaster. We use text mining and natural language processing techniques to extract impact data from humanitarian documents.
Within all these categories, any use of data must respect the ethical and practical standards we set in our data responsibility policy.
WHAT ELSE CAN WE DO
As part of our innovation efforts, we see further applications for AI, such as:
- Automated information retrieval from social media
- Automated damage assessment from mobile pictures
- Automated damage assessment from satellite images
- Building material classification from street view images
WHEN & WHERE WE STARTED
We have been working with AI since 2016, when we began developing a damage assessment tool using deep learning.
