Towards Energy-Efficient AI: Learning from the Human Brain – Anand Mahurkar

The human brain is a marvel of nature. It's an incredibly complex organ that uses very little energy. In contrast, generative AI models are very energy-intensive. This disparity in energy consumption is a significant problem, and it's one that we need to address if we want to create a sustainable future for AI.

The human brain comprises billions of neurons and operates on just 20 watts of power. That's less than a standard lightbulb! The brain can do this because it uses a very efficient way of processing information. It sends electrical signals between neurons in a very sparse and asynchronous mode. This means that the brain only uses energy when needed and doesn't waste energy on unnecessary computations.

Generative AI models, on the other hand, are very energy-intensive. Training a single generative AI model can require as much energy as several flights around the globe. And even when these models are not being taught, they still use much energy. This is because they are constantly running on powerful computers, and these computers need to be kept cool.

The high energy consumption of generative AI models is a significant problem. It's not only bad for the environment but also for the future of AI. If we want to create AI systems that are widely adopted, they need to be energy-efficient.

There are several ways to make generative AI models more energy-efficient. One way is to use neuromorphic engineering. Neuromorphic engineering is a field of engineering that is inspired by the way the human brain works. Neuromorphic engineers are trying to design computers that use the same kind of sparse and asynchronous signaling that the brain operates.

Another way to make generative AI models more energy-efficient is to use techniques like model distillation, quantization, and pruning. Model distillation is a technique that uses a large, complex model to train a smaller, simpler model. Quantization is a technique that reduces the number of bits used to represent numbers in a model. And pruning is a technique that removes unnecessary connections from a model.

We can use these techniques to make generative AI models more energy-efficient without sacrificing accuracy or performance. This is essential if we want to create a sustainable future for AI.

By looking to the brain for inspiration, we can create AI systems that are just as powerful but much more energy-efficient.

This is a future worth striving for.
