A gen AI tech stack boasts a multi-layer structure that includes a range of components necessary to develop, deploy, and maintain various AI applications. Let’s have an in-depth look at all the components:
Since the entire AI system works on data, high-quality data is a key element. It processes data from a range of channels, such as web scraping, APIs, databases, etc. Integration of these multiple data sources into a single data repository or source is necessary.
It’s possible with the use of the right data integration tools and various platforms that can handle larger volumes of data and offer seamless access.
Raw data is incomplete, so it should undergo a complete cleaning and transformation process. Data cleaning involves removing duplicates, handling missing values, and correcting errors.
The transformation process is essential for the standardization, normalization, and encoding of several categorical variables. These steps ensure that data is fed into AI models, which ensures accuracy and consistency.
ML (machine learning) models are the pillars of any AI app. Whether it’s decision trees, linear regression, or support vector machines, these models are designed to learn patterns from data and make predictions based on them.
The right model is selected based on the nature of the data and the required interpretability and accuracy. Deep learning is a subset of ML that involves neural networks with a large number of networks.
Architectures like Recurrent Neural Networks (RNNs) are appropriate for sequential data such as natural language. Meanwhile, Convolutional Neural Networks (CNNs) are the right option for image process tasks.
The computation demands of AI make it mandatory for robust hardware. Graphics Processing Units (GPUs) are mostly used due to their vast capability of performing parallel computation most efficiently.
Tensor Processing Units (TPUs) are another popular component of AI infrastructure. They’re designed specifically to catalyze ML workloads. This hardware effectively minimizes the overall time needed to train complicated models.
Cloud services offer a fully flexible and scalable infrastructure for AI development and deployment.
Many top-rated providers, including Microsoft Azure, Amazon Web Services (AWS), Google Cloud, etc., provide AI and ML services that include managed services, pre-configured environments, and various tools for processing, data storage, and analysis.
The major advantage of using cloud platforms is that they allow organizations to access robust computing resources without the necessity for substantial upfront investment in physical hardware.
Frameworks and libraries are pivotal for creating necessary AI models. As mentioned, TensorFlow, one of the popular deep learning frameworks, is known for its scalability and robustness.
PyTorch is popular for its ease of use and various dynamic computation graphs. Both frameworks include pre-trained models, vast libraries, tools for training model building, etc.
Machine Learning Operations (MLOps) tools can streamline the overall deployment and management process of ML models. These tools can support the lifecycle of ML models, from development and training to monitoring and deployment.
MLOps practices are useful when it comes to automating various repetitive tasks, enhancing model reproducibility, and thus ensuring consistency across multiple environments.
After deployment, it’s essential to monitor AI models continuously to ensure that they deliver performance as per expectations. This process involves monitoring several important metrics, such as precision, accuracy, F1 score, and recall.
Performance monitoring is helpful when it comes to identifying drifts in model accuracy due to changing data patterns, which is needed to maintain model reliability and effectiveness.
Regular updates and retaining its AI model are essential to adapting to new data and changing environments. For continuous improvement, you need to perform various activities, such as periodic retraining using fresh data, exploring new model architectures, hyperparameter tuning, etc.
There are different categories of AI tech stack. Each layer plays an important role in the life cycle of AI apps. Let’s get a complete overview of multiple layers of the AI tech stack:
