Is Training AI Models Difficult?
Training your own AI model can be a difficult and costly project, depending on the complexity of the model, its purpose, and your existing resources.
To train an AI model yourself, you need large, high-quality datasets, sufficient computational power, and the resources and time necessary to carefully design the model’s architecture. In-depth AI model training requires technical expertise that many users don’t have.

Your customers will appreciate the easy-to-use features and the Phoenix model’s exceptionally realistic digital replica technology.
Challenges in AI Model Training
Let’s review the most common challenges in AI model training.
Data Collection & Management
AI models need to be trained on high-quality data to work effectively. Training data gives AI models context and a baseline against which they can compare new data or generate new output.
For example, a model can’t automatically recognize specific images on its own—it needs to be taught. Think of those CAPTCHA login actions where you type letters and numbers from an image or choose which boxes contain a bus.
If a model learns from insufficient or poor-quality data, it won’t be able to create quality output. Data can also, like humans, be biased, such as when AI facial recognition software makes errors recognizing people of color because the dataset over-represents white people.
Tavus handles AI model training so you can provide the AI tools your end users need without needing an artificial intelligence expert on your team. You don’t have to manage large training data sets, and Tavus handles data security to ensure users can only make digital twins of themselves. All your end users need to do is provide a two-minute video of themselves so Tavus’ Phoenix model can learn their mannerisms and voice.
Infrastructure Requirements
AI and AI model training require sufficient computational power and storage capacity for training large data sets. IT departments sometimes struggle to provide adequate hardware and software for effective AI model training.
To train an AI model, you need high-performance servers and storage systems to ensure your data resources match the scope of the training project. AI training also involves various specialized software frameworks and tools, so IT teams need to ensure their existing tech is compatible with the AI software they choose and their desired model training.
Prioritizing Data Privacy
As with any technical project involving data, those conducting AI model training must ensure their data is secure. Proper AI data management is essential to ensuring data privacy. Trainers should carefully consider who will have access to training data and results and who will manage the training process.
Training data may contain sensitive information, so trainers need to ensure the privacy of those from whom their data was gathered. A data breach may expose financial information, sensitive corporate plans, and other personally identifiable information. IT departments should utilize protective measures like encryption, careful access control, and security awareness training.
Tavus makes data privacy easy for you by offering built-in security and trust. With Tavus handling end-user privacy, you can focus on user experience.
Ensuring Compliance
The principles of responsible AI set out several guidelines to ensure the ethical use of artificial intelligence. Those training or using AI should comply with these principles to protect data privacy and avoid legal ramifications. The principles of responsible AI include:
- Transparency
- Fairness and inclusivity
- Privacy and security
- Safety and reliability
- Accountability
There’s no need to worry about compliance when you choose Tavus as your AI video generator. Tavus uses comprehensive security protocols, including SOC 2 compliance, and protects your brand with automated content moderation and anti-hallucination checks.
How to Train an AI Model
Let’s take a look at the process involved in training AI models.
1. Collect the data
The first step when training an AI model is to determine what data you need and where you can get it. You might use data that is generated naturally by human technological activity or synthetic data that mimics human data but is manufactured specifically for your project.
You also need to determine what type of data you need, whether it’s text, audio, image, video, or sensor data.
2. Prepare the data
Just collecting raw data isn’t enough for use in AI model training—after collecting data, you need to prepare it. There may be uses for raw data at certain points of the training process (such as unsupervised learning), but AI training often requires labeled data, which means the data is tagged with descriptive labels to help the AI model learn. This part of the process is labor-intensive as it requires human judgment and review.
The training dataset should also go through both automated and human review to determine if the data is as consistent and unbiased as possible. Data cleaning (or pre-processing) is one step of this data validation process, involving a thorough review of the dataset to ensure labels and data quality are all consistent.
3. Select the AI model
Once you know what kind (and size) of the dataset you need, determine your existing computational resources and choose an AI model that works for your infrastructure and data. There are several types of AI training models you can choose from, including:
- Neural networks: Uses layered, interconnected nodes to learn patterns—often used for natural language processing (NLP).
- Linear regression: Identifies relationships between variables—often used for economic trends and forecasting sales.
- Logistic regression: Predicts binary outcomes—often used for medical diagnosis and credit scoring.
- Support Vector Machines (SVMs): Determines data category boundaries—often used for image recognition and text classification.
- Decision trees: Splits data into branches based on features—often used risk assessment or customer segmentation.
- Random forests: Uses multiple decision trees to improve accuracy—often used for fraud detection.
4. Choose your training technique
Optimize your AI model’s learning with an appropriate training technique. There are a few techniques, including:
- Supervised learning: Requires labeled data and pairing of inputs and outputs. Often used to classify medical images or identify credit card fraud.
- Unsupervised learning: Asks AI models to find hidden patterns in unlabeled data. Often used for customer segmentation.
- Semi-supervised learning: Combines both of the previous methods, enhancing functionality with both labeled and unlabeled data. Often used in medical image analysis and other areas where labeled data is limited or expensive.
5. Train the model
The actual training process involves feeding your prepared data into the AI model and observing the learning process to identify errors and make adjustments.
For example, it’s important to monitor the model for overfitting, which means the model memorizes data rather than learning it, which means it would fail to accurately interpret new data. Validate the model after training, testing it on a new, more complex data set to determine if the model learned or memorized your original data.
6. Test the model
At this point, your model is finally ready for testing before you launch it. Give the model an independent dataset and observe how well it performs in real-world applications. If it delivers accurate results using previously unseen data, it’s ready to go. If not, you can gather more data and conduct further training and testing to improve its functionality.
Tavus API makes this whole process much easier, as the Phoenix model is pre-trained. You don’t need artificial intelligence expertise, and your end users only need to submit a two minute training video. The process is so simple that your users can make AI videos in minutes.
Best Practices for AI Model Training
If you plan on training your own AI model, here are some best practices to help you ensure high-quality results:
- Curate and annotate data carefully: Choose data that accurately represents your model’s potential real-world applications, and tag training data consistently to support your model’s learning.
- Choose the best AI model and learning technique for your needs: Not all models and techniques provide the outcomes you need—choose ones that match your output needs, resources, and data characteristics.
- Start with a smaller dataset: By training your model first on a small but high-quality dataset, you can find problems and make adjustments more quickly during the initial training process.
- Practice rigorous model validation: Choose evaluation metrics and cross-validation techniques that can help you assess your model’s performance and implement improvements.
- Tune hyperparameters systematically: Hyperparameters are settings that control the AI training process—configure them carefully to maximize model performance.
- Practice careful and consistent documentation: Keep records of your training process and results to meet ethical parameters of transparency and to allow for easier enhancements in the future.
- Practice responsible and ethical deployment: Implement data safeguards to protect privacy and monitor data for biases to correct.
- Conduct regular training and improvements: Update your model regularly, document results, and gather feedback to ensure continued effectiveness.
