A UT Dallas research team has built a small neuromorphic computer that learns patterns using far fewer training computations than today\u2019s AI systems. The early prototype points to a future where advanced models could run on smart devices without relying on energy-hungry data centers.<\/p>\n
The work comes from Joseph S. Friedman, an associate professor of electrical and computer engineering, and his NeuroSpinCompute Laboratory at UT Dallas. His group aims to develop hardware that learns more like the human brain, cutting down the massive training requirements that make modern AI costly to build and operate.<\/p>\n
Friedman said the prototype offers an early demonstration of how neuromorphic hardware could avoid the long, expensive training cycles that define today\u2019s AI. \u201cOur work shows a potential new path for building brain-inspired computers that can learn on their own,\u201d Friedman said. He added that because these systems \u201cdo not need massive amounts of training computations,\u201d they could eventually support advanced AI on low-power devices.<\/p>\n
The research, published in\u00a0Communications Engineering<\/a>, a Nature journal, was developed with collaborators from Everspin Technologies and Texas Instruments. Friedman is co-corresponding author of the study with Dr. Sanjeev Aggarwal, president and CEO of Everspin.<\/p>\n Neuromorphic computers work differently from the systems used to train AI today. Instead of separating memory and processing, they combine both functions in one place, similar to how the brain stores and uses information at the same time. That design helps the computer learn more efficiently.<\/p>\n A probe station is used to test small neuromorphic devices in Dr. Joseph Friedman\u2019s lab.

These devices change how easily electricity flows through them, which lets the system strengthen or weaken connections as it recognizes patterns.<\/p>\n The computer learns using a neuroscience principle known as Hebb\u2019s law, often summarized as \u201cneurons that fire together, wire together.\u201d The concept describes how the brain reinforces the pathways it uses most.<\/p>\n Friedman said the team applied the same idea to their hardware. \u201cThe principle that we use for a computer to learn on its own is that if one artificial neuron causes another artificial neuron to fire, the synapse connecting them becomes more conductive,\u201d he said. In the prototype, that process helps the system strengthen the pathways it relies on to identify patterns.<\/p>\n The study also highlights the range of collaborators involved in the work. Several UT Dallas alumni contributed to the research, including first author Peng Zhou, Alexander J. Edwards, and Stephen K. Henrich-Barna, who was also affiliated with Texas Instruments. Everspin Technologies contributed through co-corresponding author Sanjeev Aggarwal and researcher Frederick B. Mancoff.<\/p>\n The project is supported by several major research grants, including a National Science Foundation CAREER award and funding from the Semiconductor Research Corp. through UT Dallas\u2019 Texas Analog Center of Excellence. In September, the U.S. Department of Energy awarded Friedman a two-year, $498,730 grant to continue advancing neuromorphic computing research.<\/p>\n The team\u2019s next step is to scale the prototype to larger sizes. If successful, the approach could make future AI systems more efficient by reducing the need for energy-intensive training and allowing more learning to happen directly on devices.<\/p>\n Don\u2019t miss what\u2019s next.
