In today’s data-driven world, machine learning and analytics require vast amounts of high-quality data. However, there are times when gathering sufficient real data is impractical due to privacy concerns or limited availability. This is where synthetic data generation tools like MOSTLY AI come into play. In this post, I’ll walk you through how to use MOSTLY AI to create synthetic data and augment your existing CSV dataset.

What is Synthetic Data?

Synthetic data is artificially generated data that replicates the patterns and structures of real-world data. It helps in boosting dataset size, ensuring privacy, and enabling better machine learning model performance by providing diverse training samples.

MOSTLY AI is one of the leading synthetic data platforms, allowing you to generate high-quality, privacy-compliant synthetic data that mimics your original dataset while preserving statistical properties.

Step 1: Preparing Your CSV Dataset

Before we dive into synthetic data generation, you need to have your CSV dataset ready. Let’s assume you have a CSV file containing customer demographic information such as age, gender, location, and purchasing behavior.

Example dataset:

Customer_ID	Age	Gender	Location	Purchases
001	25	Female	NYC	5
002	34	Male	LA	12
003	42	Female	Chicago	3

This dataset will serve as the foundation for synthetic data creation.

Step 2: Sign Up for MOSTLY AI

To start using MOSTLY AI, head over to MOSTLY AI’s website and sign up for an account. Once you’re in, you’ll be presented with an intuitive interface that guides you through the process of data synthesis.

Step 3: Upload Your Dataset

After signing in:

1. Navigate to the “Synthetic Data” section.
2. Click on “New Project” to start a new synthetic data generation project.
3. Upload your CSV dataset by selecting the file from your local storage. MOSTLY AI will parse the CSV and display a preview of your dataset.
4. Provide the project with a name that’s descriptive enough to remind you of the use case, like “Customer Data Augmentation”.

Step 4: Configure Synthetic Data Generation

Once your dataset is uploaded, it’s time to configure how you want the synthetic data to be generated.

1. Specify the features: MOSTLY AI will automatically detect your data’s features (columns). You can choose which features you want to synthesize or exclude certain columns if needed.
2. Set the number of records: You can define how many synthetic records you want to generate. If your original dataset contains 1000 rows, and you want to augment it with 5000 additional synthetic samples, you would set the row count accordingly.
3. Define privacy settings: One of the powerful features of MOSTLY AI is its privacy-preserving synthetic data generation. You can configure the privacy settings to ensure the synthetic data adheres to the required privacy standards (e.g., GDPR).

Step 5: Generate and Download Synthetic Data

After configuring the synthetic data generation process, click “Generate Data”. This process might take a few minutes, depending on the complexity and size of your original dataset.

Once the synthetic data is ready, you can download it as a CSV file.

Step 6: Augment Your Original Dataset

Now that you have the synthetic data:

1. Open both the original and synthetic CSV files.
2. Use a tool like Pandas in Python, Excel, or any database to merge the synthetic data with your original dataset.

Here’s how you can combine the two datasets using Python:

import pandas as pd

# Load original dataset
original_data = pd.read_csv('original_data.csv')

# Load synthetic dataset
synthetic_data = pd.read_csv('synthetic_data.csv')

# Concatenate the datasets
augmented_data = pd.concat([original_data, synthetic_data])

# Save the augmented dataset
augmented_data.to_csv('augmented_data.csv', index=False)

Step 7: Analyzing the Augmented Data

Once you have successfully augmented your dataset, you can begin analyzing or using it for machine learning tasks. You’ll notice that the synthetic data retains the statistical properties of the original data while introducing variations that can help improve model training.

Why Use Synthetic Data?

• Enhanced Privacy: MOSTLY AI ensures that the synthetic data is privacy-preserving, making it ideal for working with sensitive data like medical records or financial information.
• Data Diversity: Synthetic data can add variation to the dataset, reducing bias and overfitting in machine learning models.
• Availability: When real data is limited or unavailable, synthetic data fills the gap without compromising quality.

Conclusion

By following these simple steps, you can use MOSTLY AI to create synthetic data that augments your original CSV dataset. Whether you’re working on machine learning projects, analytics, or simulations, synthetic data is a valuable resource that allows for more robust and privacy-compliant datasets.

Give it a try, and see how synthetic data can transform the way you work with data!
