As the importance of data in the digital world increases every day, the principle of "Garbage In, Garbage Out (GIGO)" holds a critical place in the fields of artificial intelligence and computer engineering. This principle emphasizes that the results produced will also be erroneous if faulty, low-quality, or incorrect data is processed. Artificial intelligence models and computer systems are dependent on their inputs, thus a model trained on incorrect or misleading data cannot be expected to produce accurate results.
What is GIGO?
Artificial intelligence systems, especially machine learning and deep learning models, operate based on large amounts of data. The quality of this data directly affects the accuracy of the model. If an artificial intelligence model is trained with incorrectly labeled, incomplete, or biased data, the results obtained will also be unreliable. For example, if the data used in facial recognition systems does not represent a specific ethnic group, the system will likely be unable to correctly identify individuals from that group.
Examples
A study in 2018 revealed that some artificial intelligence-based facial recognition systems could recognize light-skinned males with high accuracy but made significant errors in identifying dark-skinned females. The reason was that the dataset on which the model was trained was imbalanced.
Chatbots can give misleading directions when fed low-quality or incorrect information during their training processes. For instance, Microsoft's chatbot Tay, released in 2016, began generating racist and aggressive messages within 24 hours by learning from harmful content on the internet, leading to its shutdown.
An artificial intelligence model conducting credit risk analysis may exhibit similar biases while evaluating future applications if the data from previous years contains discrimination against a specific ethnic group or gender. This can lead to unfair financial decisions.
GIGO from the Perspective of Computer Engineering
In the field of computer engineering, the GIGO principle manifests itself in many areas, such as software development, data management, and network systems. Faulty or incomplete data can cause software errors, system crashes, and incorrect calculations.
-Database Management: Incorrect or missing data entries can lead to data inconsistencies, causing serious disruptions in business processes. For example, incorrectly recorded customer information can lead to errors in order processing on e-commerce platforms.
-Algorithm Development: Algorithms tested with incorrect or incomplete data may not exhibit the expected performance. For example, a model predicting weather may produce incorrect forecasts when trained on erroneous or incomplete data from past years, negatively impacting agriculture, aviation, and logistics sectors.
-Cybersecurity: Systems protected with incorrectly configured or incorrect data can become vulnerable to cyberattacks. For instance, if a company's firewall is based on a misconfigured database, hackers can exploit these errors to infiltrate the system.
-Automation Systems: Robotic production errors in factories can lead to incorrect manufacturing due to faulty data, resulting in significant financial losses.
What Can Be Done to Avoid GIGO?
Use Quality Data: It should be ensured that the data is accurate, up-to-date, and complete. Automated validation systems should be used in the data collection process to minimize errors.
Eliminate Biases: Neutral and balanced data sets should be used while training artificial intelligence models. Collecting data from different demographic groups will ensure that the model works fairly across all segments.
Data Cleaning and Preprocessing: Noisy and faulty data should be filtered, and missing data should be completed using appropriate methods. Anomaly detection algorithms can be applied to identify faulty data entries in advance.
Regular Model Updates: Artificial intelligence systems should be continuously updated and improved with new data. Feedback mechanisms should be established to regularly measure model performance.
Data Source Reliability: The accuracy and reliability of the data sets used should be meticulously checked. The source of the data should be verified and cross-validated from different reliable sources.
Data Verification and Testing Processes: Algorithms and systems should be tested under various scenarios, and results should be analyzed. Testing how the model handles unexpected situations can reduce the margin of error.
Ethical and Transparency Principles: Ethical rules should be observed in data collection and processing processes, and transparent reports should be prepared regarding how algorithms work. Users should be informed about the data usage.
Ensure Data Diversity: Especially in machine learning models, care should be taken that the data sets used encompass different groups. Models trained on uniform data carry the risk of generating biases.
Social and Industrial Effects of GIGO
The GIGO principle is a phenomenon that directly affects not only the technology world but also society and industries. Systems trained with incorrect data can exacerbate social inequalities, drive financial systems to errors, and even lead to misdiagnoses in the healthcare sector. For example, a health artificial intelligence model trained with incorrect data could lead to life-threatening risks by diagnosing patients inaccurately. Additionally, the use of incorrect data in automation systems in factories can lead to increased production errors, resulting in financial losses.
Conclusion
The GIGO principle is of great importance in the fields of artificial intelligence and computer engineering. It is impossible to obtain correct results without correct data. Therefore, improving the quality of data, developing artificial intelligence models, and making computer systems more reliable is one of the fundamental requirements. Using technology more accurately and ethically will enable us to build fairer, more reliable, and efficient systems in the future.
