KEY POINTS
Liquid neural networks are making waves in the AI industry due to their unique, human brain-like, non-linear, and innovative approach, distinguishing them from their linear counterparts. They are proving to be adept at handling intricate tasks such as weather forecasting, stock market analysis, and speech recognition, areas previously mastered by human professionals.
Liquid neural networks have emerged as a critical and novel component within the realm of artificial intelligence (AI).
In situations where a machine or robot needs to respond to external stimuli or data, it can be extremely taxing on resources, leading to potential bottlenecks if the goal is to incorporate intelligence into a minimal space.
A traditional neural network, as VentureBeat explains, may require as many as 100,000 artificial neurons to maintain stability when performing tasks like driving a car down a road.
In a remarkable discovery, however, the MIT CSAIL team working on liquid neural networks managed to accomplish the same task using a mere 19 neurons.
The Genesis of Liquid Neural Networks
Liquid neural networks represent a form of deep learning structure designed to address the issue faced by robots when executing intricate learning processes and tasks, specifically the dependency on cloud-based resources or restricted internal storage.
As per Daniela Rus, the head of MIT CSAIL, in her conversation with VentureBeat, the inception of liquid neural networks was rooted in the analysis of existing machine learning methodologies and their compatibility with the safety-critical systems offered by robots and edge devices. She noted, “On a robot, you cannot really run a large language model because there isn’t really the computation [power] and [storage] space for that.”
The solution to their challenge emerged from studying the research on biological neurons present in microscopic organisms.
Pros and Cons
The research team at the Computer Science and Artificial Intelligence Laboratory at MIT (CSAIL) discovered several benefits and constraints based on their work.
Efficiency
Liquid neural networks have proved to be highly efficient, requiring far fewer neurons than traditional neural networks. To illustrate, while a conventional deep-learning neural network would necessitate 100,000 neurons to keep a self-driving car on track, a liquid neural network demands just 19 neurons.
Causality
Liquid neural networks outperform conventional deep-learning neural networks in dealing with causality. They can discern a distinct correlation between cause and effect, a task that traditional deep-learning neural networks often struggle with. For instance, the liquid neural networks can consistently recognize cause-and-effect relationships between events across various environments more effectively than the classic neural network.
Interpretability
Deciphering an AI system’s data interpretation is one of the most significant challenges in AI. Classic deep-learning models often provide shallow, vague, or incorrect rationales for data interpretations, whereas liquid neural networks can articulate their reasoning for data interpretation.
But…
Liquid neural networks are not a one-size-fits-all solution. While they excel in managing continuous data streams such as audio streams, temperature data, or video streams, they falter when it comes to static or fixed data, which are better handled by other AI models.
The Final Word
In the realm of AI, liquid neural networks are emerging as one of the most pivotal models.
While they exist alongside classic deep-learning neural networks, they seem to be more suited for extremely intricate tasks such as autonomous vehicles, climate measurements, or stock market analyses. In contrast, classic deep-learning neural networks perform better with static or one-time data.
The team at the Computer Science and Artificial Intelligence Laboratory at MIT (CSAIL) is striving to broaden the applicability of liquid neural networks to encompass more use cases, but this process will undoubtedly take time.
Both liquid neural networks and classic deep-learning neural networks have their distinct roles within the larger AI framework, reinforcing the idea that two models are indeed better than one.
