How can data cleaning help advance your machine learning career?

Data cleaning is crucial for advancing your machine learning career. It ensures that your models are trained on accurate and reliable data, resulting in more precise predictions. By identifying and rectifying errors, inconsistencies, and missing values, data cleaning improves data integrity and model performance. It also helps reduce bias and noise in the dataset, promoting fairness in your models. Skilled data cleaning showcases your attention to detail and problem-solving abilities, enhancing your professional reputation. In summary, data cleaning matters because it improves accuracy, reliability, fairness, and your overall standing in the field of machine learning.

There is a very simple rule with ML models garbage in - garbage out. So if you train your model on invaluable and messy data the output from the model will be messy and invalid. So cleaning data is very important.

Data cleaning is a critical step in the machine learning pipeline because it: 1) Improves model accuracy and reliability. 2) Enhances data understanding and informs better model decisions. 3) Mitigates biases and ensures fairness in predictions. 4) Saves time and resources by preventing downstream errors. 5) Demonstrates professionalism and boosts project credibility. 6) Advances career opportunities in machine learning and data science. 7) Contributes to research and innovation by providing high-quality data. In summary, data cleaning is essential for building accurate, reliable, and ethical machine learning models. .

Data cleaning helps in ensuring successful machine learning project by impacting the overall performance and advancement of the model 1. Improve model accuracy. ML models learns from that data they are trained on. If the data contains errors, inconsistencies or having missing values the model will learn from it and produce inaccurate results. 2. Robustness. Data cleaning helps identity and address outliers issues, making the model more robust and adoptable to variations in real-world data, ultimately improving its generalization

Cleaning data effectively involves several steps and techniques to ensure that the data is accurate, consistent, and ready for analysis or model training. 1) Identify and handle missing values, duplicates, outliers, and inconsistencies. 2) Standardize data formats and correct errors like typos. 3) Perform feature engineering to improve model performance. 4) Normalize or scale data for consistency. 5) Validate cleaned data for quality assurance. 6) Document cleaning processes for transparency and reproducibility.

As the post says, practice makes perfect. My advice would be to start from simple datasets and apply every technique you are learning. Once you know how to do it, try with different datasets and check if you cleaning could be improve. As a start point, Titanic's Kaggle dataset might be the best one.
