Limited data is a common ML challenge, particularly with startups. Consider methods to produce more data given your limited set. Look into Data Augmentation and Synthetic Data Generation. Whatever the data, Image, Tabular, Audio, or Text, there are a myriad of methods that can generate additional datapoints. Do not be afraid to experiment. Think outside of the box. Failure is a chance to learn and grow. Success is born out of perseverance.

The hard truth? Limited data doesn’t just limit your options—it demands a more strategic approach than just opting for a bigger, more complex model. Start by questioning if you’re defaulting to complex models out of habit or truly evaluating their performance with your data constraints. Often, simpler models provide better results with limited data. Explore model-agnostic techniques like ensemble learning and meta-modeling, which combine multiple simple models to boost performance by leveraging diverse perspectives on limited data. Consider unsupervised methods such as clustering and dimensionality reduction to uncover hidden patterns in your data. I will elaborate in the comments. ?? 750 characters is barely enough. ??

When navigating model selection with limited data, I often begin by researching how others have tackled similar challenges. This helps me gather insights and proven strategies from the broader community. In addition, I prioritize using pre-trained models that align closely with the task at hand. For example, when working on speech-to-text (STT) for a language like Uzbek, it's more effective to leverage a multilingual model that has native support for Uzbek. This approach not only compensates for the lack of data but also ensures better performance by building on a solid, pre-trained foundation.

When faced with limited data in model selection, especially in fields like finance, using synthetically generated data can be advantageous. For example, techniques such as Generative Adversarial Networks (GANs) allow the creation of synthetic financial data that can augment real datasets. This method helps train and test models more robustly. Additionally, choosing simpler models like linear regression can mitigate overfitting risks, making them more reliable with small datasets. Cross-validation is also essential, enabling more accurate performance evaluation. By applying these strategies, you can enhance model reliability and make informed decisions even with data constraints.

Choosing a model should prioritize simplicity and robustness when you have limited data. Compared to more complex architectures like DL, linear models and Decision Trees are less prone to overfitting. Techniques like Cross-validation help maximize the utility of the small dataset, providing more reliable performance estimates. You can also use Transfer Learning, where pre-trained models are fine-tuned to your data. Additionally, data augmentation and synthetic data generation can expand the training set, making the model more generalizable without requiring a lot of real data.
