Small AI Models Gain Traction Around the World

2 days 9 hours ago
locater16 shares a report from IEEE Spectrum: One morning in 2019, Adebayo Alonge was in a Cape Town hotel room, preparing to demonstrate his startup's AI answer to a serious problem in African health care: counterfeit medication, which kills thousands of people across the continent every year. The RxScanner is a handheld spectrometer that scans a pill with infrared light, then sends the item's molecular profile to an AI model equipped with a pharmaceutical database. In seconds, the AI identifies the medication from its molecular profile -- or reports that it's phony. Pharmacies were using the system in more than a dozen countries, including Ghana, Kenya, Myanmar, and Alonge's native Nigeria. But that morning in South Africa, it didn't work. "I was shocked," Alonge says... So Alonge immediately asked his engineers to shrink the AI model down to a smaller, low-power, unconnected version that could run entirely on his Android phone. They produced it 2 hours later, and that saved the demo. More importantly, the work birthed a new version of his device, which can authenticate a pill in places without broadband, computers, or even reliable electricity. It also turned Alonge into an advocate for this kind of "small AI." "The article goes on to detail other immediately useful 'small' AI applications without any subscription or billion dollar data centers needed," writes locator16. For example, Bala Murugan and colleagues at Vellore Institute of Technology in India developed a drone-based system that photographs cashew plants and identifies disease-indicating splotches on the plants. The key advantage is that all processing happens on the drone itself, so farmers do not need a computer, broadband connection, or cloud server access. In a Uruguayan vineyard, researchers developed small-AI systems to identify ant infestations. The article doesn't go deep into the deployment details, but it presents this as another example of a narrow, localized model trained to recognize a specific agricultural threat. Small AI has also been used to detect the presence of malaria-carrying mosquitoes in multiple countries. This is especially useful in regions where public-health teams may lack reliable network access or expensive lab infrastructure, but still need fast, local detection. In parts of Brazil without access to more complex medical equipment, researchers have used small AI to run electrocardiograms from an Arduino device. The article also describes Marcelo Jose Rovai's work on a TinyML model that generates electrocardiograms in a patient simulator lab. Rovai also describes a newer experiment using an Arduino UNO Q with a Qualcomm chipset. The device runs a language model locally, collects sensor data, and analyzes it to detect tiny pools of water where mosquitoes might breed -- while using only about 3 watts of power.

Supreme Court Allows Texas To Require Age Verification For Mobile Apps

2 days 10 hours ago
The Supreme Court allowed Texas to enforce a law requiring app stores to verify users' ages and obtain parental consent before minors can download apps. Tech industry groups argue the law broadly restricts young people's access to digital speech, but the court let a 5th Circuit order stand without explanation or noted dissents. CNN notes that the Supreme Court's decision "doesn't resolve the case but rather will allow Texas to enforce the law while the litigation continues to play out." From the report: "A minor child who downloads a software application from an app store agrees to contractual terms of service, including whether the child's location will be tracked, whether the child's privacy will be protected, whether information from the child's phone can be sold by the developer, and whether the child waives the right to sue," Texas told the Supreme Court in urging the court to allow its law to take effect. But the Computer & Communications Industry Association, a trade group whose members include Apple and Google, said the law would effectively bar young people from accessing a wide range of content, "be it a book by Ernest Hemingway or J.K. Rowling, a Taylor Swift album, or a subscription to National Geographic." Allowing the law to take effect, the group said, would have "profound consequences for the protection of digital speech." [...] In the new case, involving Texas' age verification for apps, a federal district court blocked the law's enforcement in December -- days before it was set to take effect. But a three-judge panel of the conservative 5th US Circuit Court of Appeals put that decision on hold in early June, allowing the state to enforce it. By declining to take up the emergency appeal from the computer and student groups, the Supreme Court has left the 5th Circuit's decision in place.
