Neuromorphic
Computing: What Is It?
The next big thing in AI innovation may be
human-thinking computers.
Euromorphic computing is the process of
designing and building computers so that they closely resemble the composition
and capabilities of the human brain.
Neuromorphic computers mimic the way human
brains process information by using artificial neurons and synapses. This
enables them to solve problems, identify patterns, and make decisions more
quickly and effectively than the computers we use on a daily basis.
Andreea Danielescu, an associate director at
the digital research company Accenture Labs, said, "It's brain-inspired
hardware and algorithms."
Neuromorphic computing is a relatively young
field. Beyond the research being conducted by academic institutions,
governmental organizations, and big tech firms like IBM and Intel Labs, it has
very few practical uses. Nevertheless, neuromorphic computing has a lot of
potential, especially in fields where efficiency and speed are crucial, such as
edge computing, driverless cars, cognitive computing, and other applications of
artificial intelligence.
According to Kwabena Boahen, a neuromorphic
computing scientist and professor at Stanford University, the size of the
greatest AI computations nowadays doubles every three to four months. Numerous
scientists think that Moore's Law, which only doubles every two years, might be
circumvented with the help of neuromorphic computing.
Tech analyst Daniel Bron told Built In that
"AI is not going to progress to the point it needs to with the current
computers we have." "The operation of AI is far more efficient on
neuromorphic computing. Is it required? I'm not sure if it's required just now.
However, it is unquestionably far more effective.
What
Is the Process of Neuromorphic Computing?
You must first comprehend the cognitive
processes that neuromorphic computing aims to replicate in order to comprehend
how it functions.
According to Bron, neuromorphic designs are
most frequently based on the brain's neocortex. Higher order cognitive
processes like language, motor control, spatial thinking, and sensory
perception are assumed to take place there. The extensive interconnection and
layered structure of the neocortex play a crucial role in its capacity to
handle complicated information and facilitate human thought.
The neurons and synapses that make up the
neocortex transmit and receive information from the brain incredibly quickly
and efficiently, almost instantaneously. It is what instructs your foot to move
right away in the event that you inadvertently walk on a sharp nail.
Computers that are neuromorphic attempt to
match such effectiveness. By creating what are known as spiking neural
networks, they do this. These are created when artificial synaptic devices that
transmit electrical signals between spiking neurons—which store information as
though they were biological neurons—are coupled.
An artificial neural network is a set of
algorithms that operate on a standard computer and simulate the logic of a
human brain. A spiking neural network is simply the hardware counterpart of
this system.
The
ways in which neural computing and conventional computing are different
Von Neumann architecture, the conventional
computer design that is still widely used today, is not the same as
neuromorphic computing architecture.
Information is processed by von Neumann
computers in binary, which means that everything is either a one or a zero.
Additionally, they are sequential by nature, clearly differentiating between
memory storage (RAM) and data processing (on CPUs).
In the meanwhile, millions of artificial
neurons and synapses can process many pieces of information at once on
neuromorphic computers. Compared to von Neumann computers, this offers the
system a lot more computational alternatives. Increasingly tightly integrating
memory and processor also allows neuromorphic computers to accelerate
increasingly data-intensive operations.
Since von Neumann architectures are energy
inefficient and frequently encounter data transfer bottlenecks that impede
performance, researchers are pursuing alternative architectures such as
neuromorphic and quantum. Von Neumann architectures have been the industry
standard for decades and are used for a wide range of applications, from word
processing to scientific simulations. However, as time goes on, these
architectures will become more and more difficult to deliver the increases in
compute power that we need.
Comparing
Neuromorphic and Quantum Computing
Neuromorphic computing:
is an emerging field in computing that has its own unique features, benefits,
and uses. It is inspired by the structure and functions of the human brain; it
uses artificial neurons and synapses to achieve parallel processing and
real-time learning; it works well for tasks involving pattern recognition and
sensory processing; it is logistically easier to implement than Quantum
computing; and it uses less energy than Quantum computing.
Quantum
Computing
·
Uses information processing
techniques based on quantum mechanical concepts;
·
Operates and resolves
multidimensional quantum algorithms using qubits, or quantum bits;
·
Is particularly adept at quickly
and effectively resolving challenging issues like molecular modeling and
cryptography;
·
Compared to neuromorphic computers,

Even though they are extremely distinct from
one another, both quantum and neuromorphic computing have a lot of potential
and are still in the very early phases of research and development.
Neuromorphic
Computing's advantages
Given its many advantages, neuromorphic computing
is positioned to revolutionize the field of advanced computing.

EXCIERTING
CONVENTIONAL COMPUTING
By more precisely mimicking the electrical
characteristics of actual neurons, neuromorphic devices may be able to reduce
processing time and energy consumption. Additionally, neurons can produce
replies "pretty much instantly" because to their event-driven
operation, which means that they only receive information when pertinent events
take place, according to Alexander Harrowell, a principal analyst at tech
consultancy Omdia, who spoke with Built In.
Low latency is usually advantageous, but in
technology such as Internet of Things devices that rely on real-time processing
of sensor input, it can have a significant impact.
OUTSTANDING
IN PATTERN RECOGNITION
Neuromorphic computers are very adept at
identifying patterns because of their massively parallel information
processing. As a result, Danielescu of Accenture Labs stated that they are also
adept at spotting irregularities, which can be useful in anything from cybersecurity
to health monitoring.
CAPABLE
OF QUICK LEARNING
Similar to humans, neuromorphic computers are
made to learn in real time and adjust to changing inputs by altering the
strength of the connections between neurons in response to acquired knowledge.
According to Bron, "Neural networks are
made to adjust constantly." "They are designed to evolve and improve
continuously, enabling it to get better and better.”
This adaptability can be useful in situations
where rapid decision-making and ongoing learning are required, such as when
training a robot to work on an assembly line or when allowing cars to drive
themselves through a congested city street.
POWERFUL
ENERGY
The energy efficiency of neuromorphic computing
is one of its main benefits; this might be especially helpful in the artificial
intelligence business, which is known for being inefficient.
Instead of having distinct sections for each,
as von Neumann designs do, neuromorphic computers can process and store data
jointly on each individual neuron. The ability to complete numerous tasks at
once thanks to parallel processing can result in decreased energy usage and
faster task completion. Additionally, because spiking neural networks only
process in reaction to spikes, only a tiny percentage of a system's neurons are
ever powered on at any given moment, with the remainder remaining inactive.
The
Difficulties of Neuromorphic Processing
Although neuromorphic computing has great
promise for transforming artificial intelligence applications, data analysis,
and even our comprehension of human cognition, its advancement is confronted
with various obstacles.
·
Lacks common standards for
evaluating success
·
Restricted availability of software
and hardware
·
Challenging to understand and use
·
Lower accuracy and precision when
compared to other neural networks of a same kind
Not
based on benchmarks or standards
Since neuromorphic computing is still in its
infancy, it is challenging to evaluate its performance and demonstrate its
value outside of a research lab because there are currently no accepted
standards for this technology. Furthermore, sharing applications and findings
may be challenging due to the absence of standardized neuromorphic computing
architectures and software interfaces. However, Danielescu stated that leaders
in academia and business are making a "big push" to alter this.
Restricted
Software and Hardware
One of the biggest challenges in hardware
design and production is creating neuromorphic technology that can accurately
simulate the complexity of the human brain. This is due to the fact that the
von Neumann paradigm has mostly shaped the evolution of all accepted computing
norms, such as data encoding.
Frame-based cameras, for instance, interpret
and process visual input as a sequence of discrete frames. However, information
such as changes in a visual field over time would be encoded by event-based
cameras equipped with a neuromorphic processor. This allows you to detect
motions far more quickly than you would on a conventional camera with von
Neumann architecture, but in order to fully benefit from this, new generations
of memory, storage, and sensory technology would need to be developed the
neuromorphic apparatus.
Software is no different. The majority of
neuromorphic computing that is done now uses algorithms and common programming
languages that were created for von Neumann hardware, which may have
limitations.
Diminished
Precision and Accuracy
Spiking neural networks are not immediately
mapped onto machine learning techniques that have proven successful for deep
learning applications; instead, these algorithms need to be modified. This
entails mapping a deep neural network to neuromorphic hardware, training it,
and then turning it into a spiking neural network. This adaptability may result
in a loss of accuracy and precision, as can the general complexity of
neuromorphic systems.
According to Bron, "the appropriate
software building tools don't really exist for these things." “Building
for it is still very difficult.”
Applications
of Neuromorphic Computing
Despite these obstacles, the subject of
neuromorphic computing is nevertheless well supported; one estimate puts its
value at $8 billion. And because of its exceptional capacity to replicate the
brain's information processing and learning capacities, researchers are excited
about its potential to completely transform a variety of IT disciplines.
·
Automatic
transportation
In order to travel safely and prevent
collisions, self-driving cars must make snap choices, which might demand a lot
of processing power. Self-driving cars could be able to complete tasks more
quickly and with less energy consumption than if they used traditional
computers by utilizing neuromorphic hardware and software. This can reduce
overall energy emissions and enable speedier roadside responses and
adjustments.
·
Drones
Drones with neuromorphic computing might be
just as alive as an organism, it is as receptive and reacting to airborne
stimuli. With this technology, vision-based drones might be able to navigate
tricky terrain or avoid hazards on their own. Additionally, a neuromorphic
drone can be designed to only use more energy when it senses changes in its
surroundings. This feature enables the drone to react quickly to unexpected
situations, like military or rescue missions.
·
Edge
Intelligence
Edge AI, where computations are done locally on
a machine (like a smart device or autonomous vehicle) rather than in a
centralized cloud computing facility or offsite data center, necessitates the
real-time processing of data from things like sensors and cameras. This is
where neuromorphic computing shines because of its energy efficiency,
adaptability, and real-time data processing capabilities.
Neuromorphic computing's event-driven and
parallel processing capabilities allow it to
Facilitate prompt and low-latency decision-making. Furthermore, because
of their energy efficiency, these gadgets' batteries may last longer, lowering
the frequency of edge device replacement or recharging around the house.
According to some research, neuromorphic computing actually uses batteries 100
times more efficiently than traditional computer, according to Bron.
·
Mechanisms
Robots using neuromorphic systems will be able
to perceive and make decisions more intuitively, navigate complicated
situations (such as a factory floor), identify items, and engage with people
more organically.
·
Fraud detection
Because neuromorphic computing is so good at
identifying complicated patterns, it could be able to spot tiny patterns that
point to fraud or security lapses, like strange spending habits or illegal or
fake login attempts. Furthermore, neuromorphic computing's low latency processing
could allow a swifter response once the fraud has been detected, such as
freezing accounts or alerting the proper authorities in real time.
Research
on Neuroscience
Neuromorphic computer hardware uses neural
networks inspired by the human brain to improve our understanding of human
cognition. Researchers may discover more about the inner workings of the brain
as they attempt to replicate human mental processes in technology.
Intel and Cornell University collaborated in
2020 to practically train Loihi, an anthropomorphic computer chip, to recognize
scents. The researchers eventually stated that in order to better understand
how the brain's neural circuits resolve challenging computational issues, they
would like to expand their methodology to include functions like sensory scene
processing and decision-making.
Over the course of ten years, the Human Brain
Project—an EU-funded consortium comprising about 140 universities, teaching
hospitals, and research centers—tried to replicate the human brain using two
neuromorphic supercomputers. It came to an end with its work in September of
2023
