Big data analytics can generate valuable insights and solutions from large and complex datasets that are often too much to handle for traditional statistical models. Given machine learning’s capabilities in processing and analyzing data, it has become a powerful tool in big data analysis. But when working with such datasets, challenges can also arise. Here are some of the most common roadblocks when using machine learning in big data analytics, and how to overcome them.?
1. Data quality: One of the fundamental challenges in big data analysis is ensuring the quality and reliability of the data. Data quality refers to the extent to which the data are suitable for the intended purpose, which can be affected by various factors, such as accuracy, completeness and consistency. Poor data quality can lead to biased or misleading outcomes of machine learning models, and undermine their validity and usefulness. To address this issue, machine learning practitioners can adopt a number of strategies to assess and improve data, from identifying outliers, integrating data from multiple sources and enriching the dataset with additional information or features.?
2. Scalability: Achieving scalability can be difficult with data processing, given how large and complex datasets can become. Big data analysis often poses scalability challenges, such as high dimensionality, which can require high computational and storage demands from machine learning models. Reducing the size and complexity of the data or partitioning it into more manageable chunks can make scalability more feasible. Data parallelization, which? involves distributing the data and the computation across multiple nodes or devices, might also help.?
3. Interpretability: Interpretability is the extent to which the data and the model can be understood, justified and communicated. Low interpretability can limit the trust and acceptance of the machine learning outcomes, and hinder their practical application and impact. Machine learning practitioners need to adopt comprehensive and systematic approaches to enhance the interpretability and explainability of their systems. This can include presenting the data and outcomes in more visual forms, such as charts and dashboards, or annotating the data with additional information.

4. Ethics: Those looking to use machine learning in big data analysis should ensure that they are establishing a set of ethical principles to abide by, which can include obtaining consent from data providers and users and safeguarding data from unauthorized access.?
