Top 10 Data Training Techniques to Get the Best Outcomes from Your AI/ML Project

Updated: Apr 29, 2023


In the age of artificial intelligence (AI), data is king. AI algorithms require large amounts of data to train and operate effectively. I recently wrote about the potential for synthetic data to help address AI issues such as bias, privacy, limited data, ethics, and safety. As I explained here, synthetic data is "fake" data that is artificially generated data and can be used to train machine learning models. In fairness to other viable and leading-edge alternatives to fake data, I share 10 other methods below and offer non-technical analogies and industry examples to simplify understanding. This is NOT just for techies! Business professionals need to understand these options so that they can effectively collaborate with their technology partners. Thus, to achieve the best business-enabling outcomes from training your models, I offer insights into HOW to select the most suitable alternative by taking into account factors such as:

  1. The specific needs of the project,

  2. the nature of the data that you'll be using,

  3. your available resources.


When it comes to selecting the best technique or approach for machine learning training data (alternatives to synthetic data), it's important to remember that there is no one-size-fits-all solution. Each approach has its own strengths and weaknesses, and choosing the right one for a specific situation is crucial to achieving accurate and effective machine learning models.


What are the needs of the project?

Choosing the best technique can be challenging, and it all depends on the specific needs of the project. For example, if you want to train a model without sharing data between different devices, federated learning would be the most appropriate approach. However, if you want to create more training data by making changes to existing data, like rotating or flipping images, data augmentation would be the way to go. In the same vein, unsupervised learning can be used to identify patterns in data without labels, while active learning would help you choose which data points are most informative and require expert labeling, ultimately reducing the amount of labeled data needed to train the model.


Industry Applications

There are various industry applications for different techniques. Federated learning could be used in the healthcare industry to improve patient outcomes while preserving data privacy. For example, a model could be trained across different hospitals without sharing sensitive patient data. Data augmentation could be used in the gaming industry to create more realistic environments and characters by making changes to existing data. Unsupervised learning could be applied in finance to identify fraud detection patterns in credit card transactions. Active learning could be used in the legal industry to reduce the time and cost of document review for litigation. Furthermore, semi-supervised learning could be used in agriculture to optimize crop yields by combining labeled and unlabeled data on plant health and environmental factors. Ensemble learning could be applied in the stock market to predict stock prices by combining the predictions of multiple models. Overall, the selection of the best technique depends on the specific needs of the industry and the project at hand.


What is the nature of the data that you have to work with?

Another important consideration when selecting the best approach is the nature of the data itself. For example, if the data is highly sensitive, such as healthcare data or financial data, privacy and security will be a major concern. In such cases, federated learning, which allows for the training of machine learning models across multiple devices without sharing the raw data, can be particularly useful.


Industry Applications

Understanding the nature of the data also impacts the selection of the best technique. For instance, in the retail industry, data augmentation can be used to create additional product images for online shopping, while in the automotive industry, transfer learning can be used to train models for autonomous vehicles by leveraging pre-existing models. In the marketing industry, unsupervised learning can be used to identify customer segments for targeted marketing campaigns by analyzing purchasing behavior data. In the same vein, active learning can be used in the e-commerce industry to select the most informative data points for labeling by an expert to improve product recommendation systems. Moreover, counterfactual simulation can be used in the insurance industry to generate synthetic data that represents what could have happened under different conditions, allowing companies to test hypotheses and evaluate the impact of different interventions on the system. Ultimately, the selection of the best approach depends on the unique characteristics of the data and the industry involved.


What resources do you have available?

It's also essential to consider what resources are available when choosing the best technique. For example, if you don't have many examples of labeled data, semi-supervised learning can be used to make the most of both labeled and unlabeled data and get better results. On the other hand, if you don't have a lot of computing power, transfer learning can be used to improve model accuracy by using pre-trained models and building on what they already know.


Industry Applications

Considering the resources available is crucial in selecting the best technique for a project. For example, in the transportation industry, transfer learning can be used to train models for self-driving cars by leveraging pre-existing models, ultimately requiring less computing power. Similarly, in the healthcare industry, active learning can be used to reduce the cost and time required to label medical images for diagnosis by having an expert label only the most important images, conserving resources while still achieving high accuracy. In the same vein, data synthesis can be used to generate additional training data for models in the financial industry, where the amount of labeled data is limited, by combining existing data in novel ways to increase the diversity of the dataset and reduce the risk of overfitting. Ultimately, the selection of the best technique must be tailored to the unique resources available in the industry and the specific project at hand.


What is the most important factor in choosing an approach?

Ultimately, the most important factor in selecting the technique to use is choosing the best-fit alternative for the specific situation. By carefully evaluating the situation and determining which alternative would be most effective, machine learning models can be trained more accurately and effectively, leading to better business-enabling outcomes.


Conclusion

In conclusion, selecting the right technique or approach for machine learning training data is essential to achieving accurate and effective machine learning models. While synthetic data has its benefits, it's important to explore many viable and leading-edge alternatives to identify the solution that is best suited to the specific needs of a project. By taking into account factors such as the specific needs of the project, the nature of the data, and the resources available, the best-fit alternative can be selected to train models, leading to better business-enabling outcomes. It's important for business professionals to understand these options to collaborate effectively with your technology partners for the maximum success of your AI/ML projects.
