The field of computer science has been buzzing with the advancements in artificial intelligence (AI), technologies that simulate aspects of human intelligence. Replicating human cognition, AI systems have broadened their horizons to include a plethora of tasks from identifying objects in an image to forecasting stock market trends.
From the dawn of the computer era, scientists have been on a quest to engineer AI. Initially, the focus was on creating vast databases of facts and rules for logical decision-making programs. However, the 21st century witnessed a transformative shift towards allowing machines to learn and create their own datasets – leading to significant progress in the industry.
In the past decade, AI has demonstrated extraordinary capabilities across diverse fields. Machines are identifying malignant tumors in medical images, mastering complex games such as Chess and Go, and even predicting the structure of proteins. These advancements appear to border on the “superhuman,” challenging the limitations of human ability.
One pioneering leap in AI was the introduction of conversational agents like ChatGPT. Notably, experts like Sara Hooker, the president of the research lab Cohere For AI, emphasize the importance of this progression, hinting at the proximity to what is known as Artificial General Intelligence (AGI) – an AI that mirrors the versatile intelligence observed in humans.
How does AI function?
Machine learning (ML), a subset of AI, dominates today’s landscape, focusing on allowing computers to scrutinize data and identify patterns for making predictions. Algorithms, written by human programmers, guide this data analysis, culminating in a statistical model that encodes discovered patterns. These models can subsequently generate predictions when fed new data.
The modern field of AI predominantly uses neural networks – algorithm collections modeled loosely after the human brain, known for adjusting the strengths of connections among an array of “artificial neurons.” Among these, deep learning involves neural networks with multiple layers of artificial neurons and has become a golden standard in AI research since high-performing computing units, known as GPUs, were found to accelerate deep learning processes.
AI’s neural networks exhibit diverse “architectures” depending on the tasks they are designed for. Convolutional neural networks, inspired by the animal visual cortex, excel at visual tasks, while recurrent neural networks, capable of handling sequential data due to their internal memory, specialize in processing sequences.
Moreover, algorithm training can vary with the application. Supervised learning, where humans label each data piece, is common. Meanwhile, unsupervised learning allows AI to self-discover patterns in untagged data, leading to potentially richer models. And reinforcement learning, which lies behind AI systems mastering games via trial and error, adjusts internal rules based on feedback.
Recent advancements in Large Language Models (LLMs), such as those seen in ChatGPT, offer a glimpse into the future of generative AI, capable of crafting responses based on input across text, image, and video formats. These models harness ‘transformer’ deep learning architectures, specialized for unsupervised learning on large sequential datasets. The ability to understand context better by recognizing relationships between distant data points marks a substantial leap forward, hinting at the unfolding possibilities within AI’s rapidly evolving narrative.
