“Why Smaller Data Sets Are Making Big Progress in Machine Learning Training”
Why You Don’t Need Big Data to Train ML Models?
In the era of big data, it’s become a common view that the more data you have, the better your machine learning (ML) models are. While it is true that big data can lead to better models, it is not a necessary condition for training good ML models.
Machine learning experts have long argued that the focus should be on the quality rather than the quantity of data. In other words, a small but relevant dataset can be more valuable than a large dataset of unstructured or poorly labeled data. In fact, many machine learning algorithms have been developed specifically to work with small datasets, such as transfer learning and few-shot learning.
But how does one develop a high-quality dataset? The key is in the data labeling process. Data labeling is the process of assigning a tag or a category to each data point in a dataset, such as classifying a picture as a cat or a dog. The accuracy and consistency of data labeling can have a significant impact on the quality of the ML model trained on it.
To improve data labeling quality, companies can adopt several approaches. One approach is to use multiple annotators, each labeling the same data point independently, and then comparing the results to arrive at a consensus. This approach not only improves the accuracy of labeling but also helps detect and correct potential errors in the data labeling process.
Another approach is to use active learning, where the machine learning model itself is used to identify data points that are most “uncertain” or difficult to label, and then these data points are sent for manual labeling. This iterative process not only improves the quality of labeling but also reduces the amount of labeled data needed to achieve good ML models.
In conclusion, big data is not a necessary condition for training good ML models. Rather, it is the quality of the data and the accuracy of the labeling process that are more critical. Companies must focus on developing high-quality datasets through robust data labeling processes to train highly accurate and effective ML models.
