Scientist develops multisensory neuron to make AI smarter

Researchers led by an Indian-origin scientist in the US have harnessed the biological concept for application in artificial intelligence (AI) to develop the first artificial, multisensory integrated neuron that processes visual and tactile input together.

Led by Saptarshi Das, associate professor of engineering science and mechanics at Penn State, the team published their work in the journal Nature Communication.

“Robots make decisions based on the environment they are in, but their sensors do not generally talk to each other,” said Das.

“A collective decision can be made through a sensor processing unit, but is that the most efficient or effective method? In the human brain, one sense can influence another and allow the person to better judge a situation,” Das added.

The team focused on integrating a tactile sensor and a visual sensor so that the output of one sensor modifies the other, with the help of visual memory.

The sensor generates electrical spikes in a manner reminiscent of neurons processing information, allowing it to integrate both visual and tactile cues.

The team found that the sensory response of the neuron — simulated as electrical output — increased when both visual and tactile signals were weak.

Das explained that an artificial multisensory neuron system could enhance sensor technology’s efficiency, paving the way for more eco-friendly AI uses. As a result, robots, drones and self-driving vehicles could navigate their environment more effectively while using less energy.

“The super additive summation of weak visual and tactile cues is the key accomplishment of our research,” said co-author Andrew Pannone, a fourth-year doctoral student in engineering science and mechanics.

Harikrishnan Ravichandran, a fourth-year doctoral student in engineering science and mechanics at Penn State, also co-authored this paper.

Tribal boy from Gadchiroli becomes scientist in US

Halami recalled that in the initial years of his childhood, his family survived on very little…reports Asian Lite News

From struggling to get one square meal as a child in a remote village in Maharashtra’s Gadchiroli, to becoming a senior scientist in the United States, Bhaskar Halami’s life is an example of what one can achieve with sheer hard work and determination.

Brought up in a tribal community at Chirchadi village in Kurkheda tehsil, Halami is now a senior scientist in the research and development section of Sirnaomics Inc, a biopharmaceutical company in Maryland, USA.

The company conducts research in genetic medicines and Halami looks after RNA manufacturing and synthesis.

Halami’s journey to become a successful scientist has been fraught with obstacles and he has had many firsts to his name.

He was the first science graduate from Chirchadi and first from the village to earn a Master’s degree and PhD.

Halami recalled that in the initial years of his childhood, his family survived on very little.

“We had to struggle so much to even get one square meal. My parents till recently wondered how the family survived that phase when there was no food or work,” the 44-year-old scientist said.

Some months in the year, especially monsoons, were incredibly tough, as there were no crops in the small farm that the family had and no work, he said.

“We cooked mahua flowers, which were not easy to eat and digest. We would collect parsod (wild rice) and cook rice flour in water (ambil) and drink it to fill our stomachs. This was not just us, but 90 per cent of the village had to survive this way,” Halami said.

Chirchadi is home to 400 to 500 families. Halami’s parents worked as house-helps in the village, as the produce from their small farm wasn’t enough to feed the family.

Things got better when Halami’s father, who had studied till Class 7, found out about a job opening at a school in Kasansur tehsil more than 100 km away, and reached the place by taking every available means of transport.

“My mother had no way of knowing if my father had reached the place. We only found out about him when he returned to our village three to four months later. He had landed a job as a cook at the school in Kasansur, where we later shifted,” Halami said.

Halami did his early schooling from Classes 1 to 4 at an ashram school in Kasansur, and after clearing a scholarship exam, he studied at the Government Vidyaniketan Kelapur in Yavatmal till Class 10.

“My father understood the value of education and ensured that my siblings and I completed our studies,” he said.

After earning a Bachelor of Science degree from a college in Gadchiroli, Halami got his Masters in chemistry degree from the Institute of Science in Nagpur.

In 2003, Halami was appointed as an assistant professor in the prestigious Laxminarayan Institute of Technology (LIT) in Nagpur.

While he cleared the Maharashtra Public Service Commission (MPSC) examination, Halami’s focus remained on research and he went on to pursue a PhD in the United States and chose DNA and RNA for his research, foreseeing a huge potential in it.

Halami earned his PhD from Michigan Technological University.

The top researcher now receives at least a couple of emails each week from recruiters scouting for talent in the field of DNA/RNA.

Halami gives the credit for his success to his parents, who worked hard and contributed their meagre earnings towards his education.

Halami has built a house for his family in Chirchadi, where his parents wanted to live. He lost his father a few years ago.

The researcher was recently felicitated by additional commissioner of state tribal development Ravindra Thakre in Gadchiroli.

The tribal development department rolled out its ‘A Tea with Tribal Celebrity’ programme, with Halami as its first celebrity.

Thakre also invited the scientist as a guest at a tribal hostel in Nagpur, where the latter provided guidance to students.

During his trips to India, Halami visits schools, ashram schools, colleges and even meets students at his house to counsel them about careers and ways to achieve their goals.
