When we look at the rapid rise of AI, there's one thing that's become crystal clear: data and AI are deeply connected. 

For AI to work its magic, it needs solid, clean data to process. But the kicker is getting that data clean and organized often requires the help of AI itself. It’s a bit of a chicken-and-egg situation, but once you get them working together, something truly powerful happens.

At Ideas2IT, we've been diving deep into how AI and data can come together to create something greater than the sum of their parts. We've seen firsthand how when you put these two to work in tandem, they create a shortcut to innovation—helping companies reach new heights of efficiency, insight, and creativity.

Research by Gartner claims that by 2028, the data management markets will converge into “a single market” around data ecosystems enabled by data fabric and Gen AI reducing technology complexity. 

In analytics, for instance, data is typically cleaned to remove outliers and meet human expectations. However, when training an algorithm, the data needs to be representative, which may sometimes include lower-quality data as well.

Data Analytics Evolution

Here’s how data analytics have evolved from time to time.

Past - Descriptive Analytics: In the beginning data was merely used to understand and perform statistical analysis to understand historical data, uncover patterns, and identify anomalies.

Present - Predictive Analytics: Currently, with the advent of ML/AI, algorithms are used  to forecast trends, providing insights into future events, customer behaviors, and market dynamics

Future - Prescriptive Analytics: Going forward, data will be used to provide actionable insights. AI algorithms will be capable of learning from real-time data streams to deliver prescriptive analytics that help businesses make immediate, high-impact decisions.

AI and data cleansing: The unseen revolution you didn’t know you were waiting for

You don’t need to be a tech expert to know that data is the driving force behind analytics decisions. Every click, every transaction, and every interaction leaves behind a trail of data. 

But have you ever stopped to consider the quality of that data? How much of it is truly usable? How much of it is, in fact, misleading? And more importantly, how much of it is just plain dirty?

Remember when we used to talk about "garbage in, garbage out"? Today, we're increasingly living in a world of "garbage in, perfection out". This is where data cleaning comes in. It is an often-overlooked process that is becoming far more than just an operational task. 

Traditionally, data cleaning has been a manual, tedious, and often error-prone process. Human intervention, even with the best intentions, cannot keep up with the exponential growth of data. 

The real cost of poor data management goes beyond errors. Organizations face:

• Delayed AI/ML deployments
• Compromised model accuracy
• Resource drain on technical teams
• Missed market opportunities

As data volumes grow exponentially, organizations need systems that:

• Scale automatically with data growth
• Adapt to new data patterns
• Secure sensitive information
• Integrate with existing workflows
• Maintain compliance standards

The 4 I’s of ‘dirty’ data

It’s easy to assume that as long as we have data, we’re fine. But the reality is far more dangerous. We rely on data in ways that are deeper and more pervasive than ever before. 

AI is learning from it, algorithms are acting on it, and companies are building empires based on it.

Yet, the data we collect is far from perfect. Missing values, outliers, duplicates, inaccurate information — this is the dirty data we’re working with every single day.

Inaccurate Data

Inaccurate data refers to information that is incorrect or misleading. This can arise from human errors during data entry, such as typos or misentered values, as well as technical issues like incorrect data types being used. 

Incomplete Data

Incomplete data occurs when critical information is missing from a dataset. This could involve missing fields in customer records or incomplete transaction histories. Such gaps can hinder effective analysis and decision-making, as businesses may lack the full picture needed to understand their operations or customer needs

Inconsistent Data

Inconsistent data arises when the same information is represented in different ways across datasets. This might include variations in naming conventions or conflicting values for the same entity.

Incompatible Data

Incompatible data refers to information that cannot be effectively integrated due to differences in format or structure between datasets. This issue often arises when merging data from various sources that do not follow the same standards or protocols

Specific use cases of AI in data cleansing

By utilizing machine learning models, AI can detect and rectify data quality issues such as missing values, inconsistencies, and outliers. Here are some of the specific use cases where AI can be used in data cleansing.

Error Detection and Correction

AI algorithms, like Natural Language Processing (NLP) or Spell Checking Algorithms, can automatically detect spelling errors, inconsistent data entries, or improperly formatted values (e.g., dates, phone numbers).

Missing Data 

Machine Learning (ML) models like K-Nearest Neighbors (KNN) or Random Forests can predict missing values based on correlations and trends observed in other related data points.

Example: In a sales dataset, if a transaction record lacks the price field, AI can predict the price based on historical data for similar transactions.

Duplicate Detection

Clustering algorithms such as K-Means or DBSCAN can group similar data entries, while Deep Learning methods can identify highly similar or near-identical records even when they are expressed differently (e.g., "John Smith" vs. "J. Smith").

Data Type Validation

AI models can analyze datasets to automatically detect type mismatches (e.g., text in a numeric field) and correct them based on learned patterns.

Example:“$1,000” to “1000” or “01/12/2022” to a consistent date format.

Outlier Detection

Anomaly detection algorithms such as Isolation Forest, and Support Vector Machines (SVM) can automatically detect anomalies or outliers in large datasets and flag them for review or removal.

Example: In financial transactions data, AI can detect outliers such as a transaction of $1 million when the average transaction is around $100,000, and flag it for further review.

Data Standardization

AI can identify patterns in how data is recorded and automatically standardize them. This may include converting abbreviations or varying units to consistent standards (e.g., “inches” to “cm”) or various address formats into a single, consistent format.

Contextual Validation

Using Deep Learning or Rule-based AI, the system can validate that data entries adhere to contextual rules by analyzing data relationships (e.g., ensuring an employee isn’t listed as hired before their birth year).

Data Consistency

AI-powered comparison models can check for discrepancies between various datasets or data pipelines, ensuring data integrity and consistency.

Example: AI can check that the quantities of products in an inventory system match those in shipping logs and update discrepancies automatically.

‍

Anomaly Detection

Anomaly detection is a key component of ensuring data quality, security, and operational stability. Traditionally, it’s been about setting thresholds and hoping that outliers don’t slip through the cracks. 

But as data grows more complex, static thresholds become increasingly unreliable. What happens when the anomalies are subtle, or when data flows in unpredictable patterns?

This is where AI can help. Rather than simply flagging outliers based on rigid rules, AI can learn what “normal” looks like and identify deviations with context. 

Anomalies are found in different types. A few of them include:

• Outliers: Data points that are far removed from the rest of the data (e.g., an unusually high transaction amount or an extremely low-temperature reading).

• Trends or Behaviors: Unusual changes in data trends or behaviors over time, such as a sudden drop in website traffic or a sharp increase in customer complaints.

• Errors or Data Quality Issues: Mistakes in data collection, entry, or processing, such as incorrect sensor readings or typographical errors in data records.

These anomalies can be identified by numerous methods. These methods can be divided into three main types namely:

• Statistical Methods: These involve analyzing data distributions and flagging values that significantly deviate from expected ranges or patterns.

• Machine Learning Approaches: Unsupervised learning algorithms (such as clustering or autoencoders) can detect anomalies without labeled data, while supervised methods (using labeled data) can train models to identify specific types of anomalies.

• Rule-Based Systems: These use predefined rules or thresholds to detect anomalies, such as a transaction exceeding a certain amount or a temperature reading crossing a critical threshold.

Effective anomaly detection helps businesses quickly identify potential problems, prevent costly issues, improve security, and make more informed decisions

‍

Use cases of anomaly detection across industries

The anomaly detection powered by AI can be implemented across a range of industries and use cases. Here are a few to name.

• Fraud detection: Identifying suspicious activities like unusual credit card transactions or abnormal login patterns.

• Network security: Detecting potential security breaches or unauthorized access based on abnormal network traffic or access patterns.

• Manufacturing and maintenance: Spotting machine malfunctions or quality control issues by recognizing unusual sensor readings.

• Healthcare: Detecting rare diseases or out-of-norm medical conditions in patient data.

Data Lineage

As data becomes increasingly distributed across systems, tracking its lineage—understanding where data comes from, how it flows through the organization, and where it ends up—becomes crucial. The challenge is not just mapping this flow, but ensuring accuracy and maintaining trust in the data.

This is where AI's ability to automatically generate data lineage maps shines. For CTOs, the real value of AI in data lineage lies in the way it fosters transparency and accountability. The ability to instantly trace the path of any dataset through the enterprise provides a level of auditability and compliance that is increasingly required by regulatory standards. 

By understanding the flow of data, organizations can better manage risks, improve decision-making, and more effectively enforce data governance policies. 

Moreover, AI’s role in data lineage isn't just about tracking; it's about enhancing data collaboration. By connecting the dots across various silos and systems, AI empowers teams to understand the full context of the data they’re working with.

The concept of data lineage is crucial in data management for several reasons, including:

• Traceability: Data lineage allows organizations to trace back the origins of any data point, making it easier to identify errors, validate data quality, and ensure accuracy in reporting.

• Compliance: With growing data privacy regulations (e.g., GDPR), understanding how data moves and is transformed within an organization helps ensure that compliance standards are met, and data privacy is maintained.

• Data Quality: By understanding the flow and transformation of data, organizations can identify areas where data quality may degrade or be corrupted, allowing them to take corrective actions.

• Collaboration: It also enables better collaboration between different teams (e.g., data engineers, analysts, and business stakeholders) by providing a shared understanding of the data's journey.

• Impact Analysis: If a data change or update is made in one system, lineage helps assess its downstream impact, helping organizations avoid disruptions or issues that could arise from unforeseen changes.
