Multiple journals and conferences accepted papers in recent weeks from the Mobile Artificial Intelligence (mAI) Lab at Purdue University’s Polytechnic college.
The mAI Lab, directed by Sudip Vhaduri, emphasizes AI and mobile and wearable computing to develop secure, impactful solutions that enhance individuals’ quality of life through interconnected personal devices like smartphones and wearables in the IoT (Internet-of-Things) ecosystem.
“It’s impressive for any research team to have several papers accepted by prominent journals and conferences in a short period of time,” said Vhaduri, assistant professor of data analytics and machine learning. “Mobile artificial intelligence is a rapidly evolving domain. Our current students should be celebrated for this achievement, and I hope it also inspires future students to join our research team.”

Growth in AI and IoT research
The mAI Lab’s string of publications further cements the college’s reputation in the AI and IoT space, according to Tom Hacker, professor and head of the Department of Computer and Information Technology.
“The recent accomplishments of the mAI Lab epitomize the blend of dedication, innovation, and collaboration at Purdue Polytechnic,” said Hacker. “Our budding researchers are not just pushing boundaries but are also setting new benchmarks. This is just the beginning, and we’re excited about the future.”
Note: In academia, research publications' quality and influence are evaluated using specific metrics. One such metric is the 'impact factor,' which measures how frequently a journal's articles are cited in scholarly literature. A higher impact factor indicates a more influential journal, with values varying across disciplines. For instance, in computer science and information technology, top journals often have impact factors above 5.
Conferences also employ a benchmark called the 'acceptance rate' to assess quality. In our field, a lower acceptance rate reflects a more competitive conference. Generally, an acceptance rate below 30% is mentionable.
