AI’s effectiveness heavily relies on data availability for training purposes. However, a study by University of Toronto Engineering researchers suggests that deep learning models may not always require a lot of training data. The researchers found that smaller subsets of data can be used to train models without compromising accuracy. The study emphasizes the significance of information richness over the volume of data alone, prioritizing data quality.
Researchers from the University of Toronto Unveil a Surprising Redundancy in Large Materials Datasets and the Power of Informative Data for Enhanced Machine Learning Performance
The use of AI is becoming increasingly prevalent in all aspects of our lives. However, AI relies heavily on data for training, and traditionally, the accuracy of AI models has depended on the availability of large amounts of data. This poses a challenge, as analyzing and developing models on such datasets require significant computational resources.
Researchers at the University of Toronto Engineering have discovered that deep learning models may not always require extensive training data. They propose finding smaller subsets of data within large datasets that contain all the necessary diversity and information for model training but are easier to handle during processing.
To test this hypothesis, the researchers developed methods to locate high-quality subsets of information from publicly available materials datasets. They found that a model trained on just 5% of the original dataset performed comparably to a model trained on the entire dataset when predicting material properties within the dataset’s domain. This suggests that up to 95% of the data can be safely excluded during machine learning training without significantly impacting accuracy.
The study highlights the importance of information richness over the sheer volume of data. It emphasizes that the quality of the data is crucial, and adding more data does not necessarily improve model performance if it is redundant and does not provide new information for the models to learn.
