☄️ What is an Artificial Neural Networks?

Artificial neural networks (ANN) give machines the ability to process data similar to the human brain and make decisions or take actions based on the data. While there’s still more to develop before machines have similar imaginations and reasoning power as humans, ANNs help machines complete and learn from the tasks they perform.

6 Tips for Building a Robust Machine Learning Model

1. Understand the problem thoroughly before jumping into the model.
➝ Taking time to understand the problem helps build a solution aligned with business needs and goals.

2. Focus on feature engineering to improve accuracy.
➝ Well-engineered features make a big difference in model performance. Collaborating with data engineers on clean and well-structured data can simplify feature engineering.

3. Start simple, test assumptions, and iterate.
➝ Begin with straightforward models to test ideas quickly. Iteration and experimentation will lead to stronger results.

4. Keep track of versions for reproducibility. 
➝  Documenting versions of data and code helps maintain consistency, making it easier to reproduce results.

5. Regularly validate your model with new data.
➝ Models should be updated and validated as new data becomes available to avoid performance degradation.

6. Always prioritize interpretability alongside accuracy.
➝ Building interpretable models helps stakeholders understand and trust your results, making insights more actionable.
