Create a Custom AI Model

Supervised machine learning harnesses the power of labeled datasets to train algorithms, enabling them to accurately classify new inputs based on learned patterns. Developing a custom machine learning model for text classification involves tailoring this technology to label and organize text data, such as customer feedback or product reviews, according to specified criteria. The key to building an effective classification model lies in meticulously preparing your training data. Follow this article to organize and refine your data for optimal model training and performance.

Create a training  set

A training set is a collection of data specifically assembled to teach your machine learning model how to recognize patterns and make predictions. It contains examples of inputs, along with their correct outputs, which the model uses to understand how to generalize this knowledge to new, unseen data. The quality and diversity of your training set are vital, as they directly influence how effectively your model learns and performs on real-world tasks. By curating a well-labeled, clean, and comprehensive training set, you're laying the foundation for a robust and accurate machine learning model.

1. Goal Setting

• Define the purpose of your text classification model clearly. Specify whether you aim to categorize customer reviews, segment user feedback, or classify support requests, ensuring that your project's objectives dictate your approach to data collection.

2. Data Collection

• Gather a diverse and comprehensive set of text data related to your goal. For instance, if building a model for e-commerce reviews, collect data from platforms like Amazon or Etsy. Ensure this data encompasses a variety of topics and tones to train your model effectively.

3. Data Cleaning

• Clean your dataset by removing errors, inconsistencies, and any meaningless content, such as entries full of emojis or isolated punctuation marks. This step is crucial to ensure the model only learns from relevant and coherent text samples.

A clean dataset means that links, nouns, numbers, and names should be deleted from each row. Here is a quick guide to deleting those with Google Sheets automatically.

4. Data Labeling

• Label your text data to prepare it for supervised learning. Use specific and relevant labels like "product quality," "customer service," or "pricing" to categorize the text. Ensure your labeling scheme remains clear and consistent across your dataset.
• Keep in mind, each sector has its own unique categories. If there are specific KPIs you want to track, such as "product returns" or "repeat purchases," tailor these as labels and mark them consistently within your training dataset. This will help teach your model to recognize and focus on these important aspects.

Target a minimum of 500 samples per label, with a recommended count of 2,500 to provide robust training instances. Limit your model to 2–8 labels for optimal performance.

5. Splitting the Data

• Reserve 20-30% of your data as a test set to evaluate your model's accuracy post-training. This test set is crucial for validating the model's ability to classify data it hasn't seen before.

6. Shaping the Training Set

• Format your labeled data in a structured manner that suits machine learning environments. Use a spreadsheet format like CSV or Excel, ensuring that each entry is well-organized and easy for the model to process.

By diligently following these steps, you can develop a high-quality training set that will enable your machine learning model to efficiently classify text data. The thoroughness with which you prepare your data has a significant impact on the model's capacity to accurately interpret and categorize new information.

How to Create a Custom AI Model?

Creating a custom machine learning model can be an empowering experience, especially when you don't have to worry about writing a single line of code. With Kimola, building a machine learning model tailored to your data needs is a straightforward process. This guide will walk you through the necessary steps, ensuring you can start leveraging your personalized model without the hassle. Follow along to create a model using your training data in just a few simple steps.

1. Log into Your Kimola Account

• Start by logging into your Kimola account and accessing the Kimola's dashboard to manage your model creation activities.

2. Access the Models Section

• On the left panel of the Dashboard, find and click on "Models" to explore your machine learning model options.

3. Select the Custom Tab

• Under the Models section, you'll see two tabs: Pre-Built and Custom. Click on the "Custom" tab to start building your personalized machine learning model.

4. Initiate Model Creation

• Click the "+" icon located in the upper right corner of the page to begin the process of creating a new custom model.

5. Upload Your Training Set

• Drag and drop your pre-prepared training set into the designated upload area, or use the arrow sign to browse and select the file.

6. Map the Training Set

• In the preview window that opens, specify the column containing the data you want to classify under the "Content" section. Then, select the column with the labels under the "Label" section. Once you've set up your training data, click the "Next" button to move forward.

8. See the Label Distribution

• When creating a machine learning model, one of the other steps is examining the label distribution. You can see the number of data for each label in your training set at this stage.

9. Finalize Your Model

• In the final step, give your model a descriptive name and choose the appropriate category. Once completed, click "Complete". Your model's training will be processed in the background and ready in a short time. 

10. Go to Model

Once your model is successfully created with the training set, the following screen will appear. On this screen, you can quickly test your model if you wish. Additionally, you can navigate to the model's page using the "Go to Model" button located at the bottom of the screen.

By following these steps, you can effortlessly create a machine learning model tailored to your data, enabling more targeted analysis and insights.
