Is Your Machine Learning Model Lost in Translation?
Why National Culture Matters for ML Model Design
Read Time: 5 mins
Just a month ago, I arrived in Doha, Qatar. I was there for an assignment with a client who was eager to integrate machine learning into their work.
As we delved into the nitty-gritty of their operations and potential ML applications, a recurring question started to surface. How do we ensure a machine learning strategy is not just technically sound, but also culturally attuned? Or simply, how do we make Machine Learning feel at home in our organization?
This wasn't the first time I'd encountered this question. I’ve dealt with it before working with clients in the Asia Pacific region, working with machine learning and analytics. It’s a factor that often gets overlooked.
I’ll be breaking it up into two parts, so that I can explain in better detail.
In Part 1 and Part 2 I’ll explain:
How foreign cultures can affect how you collect your data. (Part1)
How it can affect data interpretation. (Part 2)
How it effects Machine Learning Model Development (Part 2)
Lets get started.
Why Does Cultural Context Matter?
Culture is the sum of shared values, beliefs, norms, and practices that define a people.
For the forward-thinking business, culture is more than a checklist; it's a rich tapestry that infuses our world with diversity. It's language, religion, social norms, traditions, and artistic expressions. Each of these elements has a crucial role in shaping machine learning and AI projects.
In the realm of business, cultural understanding isn't just a nice-to-have –it's a powerful asset. Today, businesses are not confined to local markets. They're playing on the global field, interacting with customers, employees, and partners from various cultural backgrounds.
In the era of Machine Learning (ML) and Artificial Intelligence (AI), cultural understanding has never been more critical. Businesses are no longer interacting within a single cultural context. But with with a global audience with diverse cultural backgrounds. That's why a genuine understanding and appreciation of different cultures is an absolute must.
MLOps processes are much more than tools - its how you pace it. Check out our article on ops tempo here:
Understanding and deep appreciation of culture becomes the bridge connecting you with diverse customers. It fosters trust, nurtures relationships, and smooths the path of communication across the vibrant tapestry of global cultures.
But it does more. It becomes the compass guiding your AI and Machine Learning projects. Ensuring they are tailored to embrace the unique needs of each cultural group.
This is the key to ensuring your ML models stays not just relevant, but impactful across the vast, dynamic expanse of the global marketplace.
So How Does Culture Affect data Collection?
Using machine learning in business can be a game changer. But, we need to be careful about how culture can affect our data and models. If we don't collected the data right, we might end up with biased results that don't work for everyone. Let's look at three common problems and how we can solve them.
Overcoming Bias in Data Collection and Labeling
Problem: Machine learning models trained on data predominantly from one cultural group may not perform well for others. Cultural bias gets injected into the model’s idea of reality.
Solutions:
Diverse Data Sources: Gather and incorporate data from a wide array of cultural backgrounds. Partner with international organizations or source data from globally diverse user bases. Be methodical in how you sample.
Unbiased Labeling: Train your data labeling team to recognize and avoid cultural bias. This could involve cultural sensitivity training and creating guidelines for neutral data labeling.
Model governance: Regularly employ external and internal experts to review your data collection and labeling processes. Potential biases do exist, so get people familiar with the culture to audit them.
Addressing the Data Availability Gap
Problem 1: Certain cultures may produce more digital data due to higher technology usage, leading to over-representation of these cultures and under-representation of others in your data.
Solutions:
Balance Your Data: You may have to do manual work. Especially in cultures that have lower technology interaction. This can involve conducting offline surveys or partnering with local organizations to obtain the data.
Partner with Local Experts: Collaborate with local entities or experts who understand the cultural nuances and can help in data collection, ensuring representation of under-represented cultures.
Privacy-conscious Data Collection: Develop and communicate robust data privacy policies to assuage privacy concerns in cultures with lower technology interaction. This can encourage more participation and data generation.
Mastering Cultural Context and Language Nuances
Problem 2: Machine learning models can often misinterpret culturally specific contexts and language nuances, leading to inaccuracies.
Solutions:
Data Evaluation: Before training, be sure to scope properly to account for cultural contexts or project requirements. Document this as much as possible, before you build. This could involve using culturally annotated datasets or integrating context-aware models.
Multilingual Models: Build machine learning models capable of understanding and processing multiple languages. This could involve using multilingual datasets for training or implementing language translation services in your model.
Localizing Models. Consider developing separate models tailored for different cultural contexts or geographic regions. These models can be trained on region-specific data to capture local nuances more accurately.
ML models are snapshots of reality, based on assumptions of the builder. So its absolutely essential to account for cultural factors during data collection for your machine learning (ML) project. The collection phase acts as the critical foundation for the entire journey.
To ensure accurate and unbiased ML models, you need to establish, survey, and understand the cultural limitations of the data.
Think of it this way: just like you lay a strong foundation before building a house, laying a solid cultural groundwork in data collection sets the stage for success in your ML project. By being mindful of cultural nuances and biases from the very beginning, you can ensure the accuracy, fairness, and resonance of your ML models.
How does culture affect data interpretation?
The Effect of Bias
Bias is a major roadblock in machine learning data collection. If the bulk of your data is sourced from a particular cultural group, there's a risk of developing a model that's skewed towards that group. This bias can affect diverse sectors, from NLP to facial recognition and recommendation systems. It limits potentially limiting the applicability of your models across various demographics.
Additionally, during the manual labeling process in supervised learning, there's a risk of human-driven cultural biases creeping into the data. This can result in models that perform inconsistently across different cultures, limiting your solutions' global scalability.

The Problem
Cultural Bias: Machine learning models may become biased if mainly trained on data from a particular cultural group. For instance, a recommendation system trained predominantly on Western data might not accurately suggest products for Middle Eastern customers. This bias could negatively impact various applications like natural language processing, facial recognition, and recommendation systems across diverse demographics.
Cultural Context and Language Nuances: Machine learning models can misinterpret culturally-specific meanings. For example, a thumbs-up gesture is generally positive in Western cultures but can be offensive in some Middle Eastern countries. Ignoring such cultural context might lead to errors in data interpretation, impacting the effectiveness of your business strategies.
Solutions
To address these challenges:
For Cultural Bias:
Diversify your data sources to include various cultural groups, reducing the bias and enhancing the model's performance.
Implement bias-detection mechanisms during the manual labeling process to counteract human-driven cultural biases.
Regularly validate and update your models to ensure their applicability across various cultural demographics.
For Cultural Context and Language Nuances:
Annotate data with cultural information during the preparation process or use techniques enabling models to learn cultural subtleties directly from the data.
Develop multilingual models to better interpret and process various languages, enhancing performance across diverse linguistic groups.
Incorporate feedback mechanisms to continually learn and adapt to evolving cultural contexts and language nuances.
How is Model Development Affected?
In the global marketplace, businesses must cater to diverse cultures. This cultural diversity affects not only the end-use of machine learning models but also their development process, including project management, feature engineering, and the setting of Key Performance Indicators (KPIs).
The Problem
ML Project Management: Team members from diverse cultures can have different communication styles, work ethics, or problem-solving approaches, which can influence the pace and direction of the project.
Example: A project managed across teams in different geographical locations might face challenges due to differences in work hours, communication styles, or understanding of deadlines.
Feature Engineering: Cultural nuances can affect the selection and creation of features used to train machine learning models.
Example: In a credit scoring model, features like income and credit history might be readily available and predictive in one country, but not in another where income is less formalized or credit systems are less established.
Setting KPIs: Cultural context can influence the definition of success and the setting of KPIs for a machine learning project.
Example: A customer churn prediction model for a telecom company might use different KPIs in different markets (or even different features), as customer behavior and expectations may vary across cultures.
