One such domain is scientific research, where AI is playing a transformative role. Led by renowned AI researcher Yoshua Bengio, a team has showcased the intersection of AI and scientific discoveries, highlighting how AI is reshaping the process of scientific exploration and becoming the engine for scientific breakthroughs.

AI for Science focuses on how AI can assist in scientific discoveries and technological advancements. This article examines the potential of AI in different stages of scientific research, including hypothesis construction, experimental design, and data collection and analysis. It explores the applications of self-supervised learning, geometric deep learning, and Generative AI in scientific research. However, despite the progress made, there are still challenges to address, such as data standardization, model generalization, and the integration of scientific knowledge.

AI-Assisted Data Collection and Annotation 🗃️

Data plays a pivotal role in scientific research, serving as the foundation for insights and discoveries. AI can significantly enhance the data collection and annotation process, making it more efficient and accurate.

Data Selection

In many scientific experiments, a vast amount of data is generated, but only a small portion contains valuable information. AI can help with data selection by using anomaly detection algorithms to identify and retain rare and valuable data points. This strategy has found applications in various fields such as physics, neuroscience, earth sciences, oceanography, and astronomy.

Data Annotation

Training supervised models often requires labeled datasets, but generating accurate labels can be time-consuming and labor-intensive, especially in experimental disciplines like biology and medicine. Semi-supervised learning methods offered by AI enable automatic annotation on large unlabeled datasets, utilizing techniques like pseudo-labeling and label propagation. Active learning techniques can also identify the most informative data points for human annotation or determine significant experiments, thus reducing costs.

Data Generation

The performance of AI models improves with high-quality, diverse, and large-Scale training datasets. Automated data augmentation and deep generative models can generate additional synthetic data points, enriching the training dataset. Reinforcement learning methods can also discover automatic data augmentation strategies without relying on specific downstream tasks. Generative adversarial networks (GANs) have demonstrated their usefulness in generating realistic and valuable data in multiple domains, from particle collision events and pathology slides to chest X-rays, nuclear magnetic resonance imaging, three-dimensional material microstructures, protein functions, and genetic sequences.

Data Refinement

High-precision instruments can directly or indirectly measure physical quantities with great accuracy. AI can further enhance measurement resolution, reduce noise, and minimize measurement errors. Deep convolutional networks can transform low-quality, low spatiotemporal resolution data into high-quality, high-resolution, and structured images. Denoising autoencoders can project high-dimensional input data into a more compact and essential feature representation. Variational autoencoders (VAEs) capture latent representations through unsupervised learning and preserve fundamental data characteristics while ignoring non-essential variations. Examples of applications include black hole imaging, capturing physical particle collisions, improving resolution of live cell images, and cell type detection.

Extracting Valuable Representations from Scientific Data 📊

In scientific research, extracting Meaningful representations from data is crucial for guiding research and discovering new knowledge. These representations should be concise, informative, distinguishable, and have the ability to generalize to downstream tasks. Several emerging strategies have been introduced to meet these requirements.

Geometric Priors

Applying geometric priors enables capturing the geometric and structural properties of data, which is particularly important in scientific domains. Symmetry is a key concept that describes the behavior of mathematical functions under a set of transformations, providing invariance and equivariance. By incorporating symmetry and other factors into models, AI can improve its applications even with limited annotated datasets. Increasing the training samples can enhance extrapolative predictions when faced with significantly different inputs during model training.

Self-Supervised Learning

Self-supervised learning leverages unlabeled data to learn general features. Common strategies include predicting occluded regions in images, predicting consecutive frames in videos, and learning to differentiate between similar and dissimilar data points through contrastive learning. Pretrained models from self-supervised learning can extract features from large-scale unlabeled datasets and be fine-tuned with limited annotated data. Language modeling is also a popular self-supervised learning approach, applicable to learning features from natural language and biological sequences. In training, the main objective is to predict the next token in a sequence. Masked training on sequences aims to recover the masked tokens by utilizing bidirectional contextual information. Arrangements of atoms or amino acids are similar to how letters form words and sentences, defining the structure of molecules and biological functions. Therefore, protein language models can encode amino acid sequences, capturing their structural and functional characteristics and evaluating viral variation.

Language Modeling

Language modeling is another form of self-supervised learning that can be used to learn features from natural language and biological sequences. The main objective during training is predicting the next token in a sequence. Masked training involves recovering masked tokens in the sequence using bidirectional contextual information. These principles are analogous to how letters form words and sentences, defining the structure and function of molecules. Protein language models can encode amino acid sequences, capturing their structure and functional characteristics, and evaluate the evolutionary adaptability of viral mutations.

Generating and Evaluating Scientific Hypotheses with AI 🧪

Hypotheses, in various forms such as mathematical expressions, chemical molecules, and genetic variations, are crucial for scientific discoveries. Constructing meaningful hypotheses can be a time-consuming and labor-intensive process. AI can play a role in multiple stages of this process by identifying candidate symbol expressions from noisy observations, designing objects such as molecules that can interact with therapeutic targets, or generating counterexamples that challenge mathematical conjectures. These hypotheses lead to laboratory experiments for evaluation.

AI can learn the Bayesian posterior distribution of hypotheses and generate hypotheses that Align with scientific data and knowledge. Three emerging strategies for hypothesis generation are:

  1. Black-box Predictors: Rapidly filter candidate hypotheses and select promising ones for further verification.
  2. Navigating Hypothesis Space: Use reinforcement learning to evaluate the return on search actions, focusing on the most promising hypothesis elements.
  3. Optimizing Differentiable Hypothesis Space: Map discrete hypothesis spaces to continuous, differentiable spaces for optimization.

These AI methods provide powerful tools for generating, evaluating, and selecting scientific hypotheses.
