How to Learn Generative AI?
When it comes to finding an answer to how to learn Generative AI from scratch, there are various things that you must consider. One of the key aspects is to judge how good your current knowledge is, and how much you still need to learn about the associated topics. Here are a few technologies, topics, tools, and aspects you need to get started in this field.
1. Learn the Fundamentals
To learn anything, you must be clear about the fundamentals, and the same is true when it comes to figuring out how to learn Generative AI. Here are the key pointers to begin with.
- Linear algebra offers the key mathematical operations to work with tensors, matrices, vectors, and various other multi-dimensional arrays in ML.
- Probability accommodates techniques such as Bayesian statistics, which is employed to make probabilistic predictions and statistical distributions.
- TensorFlow and PyTorch are key open-source libraries to develop and train ML models.
- Calculus is employed to optimize ML algorithms. Gain an understanding of key concepts like curve fitting, multivariate calculus, derivatives, interaction, and gradients.
- Python is the widely preferred programming language for ML. This aspect includes control flow, tools like Pandas and NumPy, object-oriented design, and data structures.
- Statistics offers the techniques to analyze ML data. Hence, you must learn descriptive statistics, regression, statistical reasoning, inference, and significance testing.
2. Understand Machine Learning
A subset of artificial intelligence, machine learning, or ML focuses on building systems with the ability to learn from data sets and improve with time. The top ML approaches to learn about are.
- Supervised Learning means training of the algorithm on labeled data sets, offering instances of the input and the intended output. The famous supervised learning algorithms incorporate decision trees, support vector machines, linear regression, k-nearest neighbors, and logistic regression. In addition, Cybersecurity skills can help in both AI/ML.
- Unsupervised Learning means analyzing data sets with just the inputs and no labeled responses. The aim is to uncover interest structure and relationships within the data.
- Artificial Neural Networks are inspired by biological neural networks and are made up of multiple layers of interconnected nodes like neurons. This knowledge is important to ensure fluent working.
- Reinforcement Learning means training algorithms for maximizing the trial-and-error interactions with the environment they are in. Training the data sets is not required as the agent learns by achieving their goals by getting feedback on their actions about which one is the better one.
3. Convolutional Neural Networks (CNNs)
A specialized kind of neural network, CNNs are apt for image processing. Convolutional layers are utilized to preserve spatial relationships within pixels. It is followed by pooling layers to further reduce dimensionality. It is important to learn about CNN architectures such as YOLO, ResNet, and VGG for Generative image modelling.

Generative Adversarial Networks or GANs are composed of a discriminator neural network and a generator neural network, competing against one another. The task of the generator is to create synthetic data samples, whereas the task of the discriminator is to distinguish between the real and the fake one. You must gain knowledge of Sequence GANs for text generation, WaveGANs for audio generation, and Deep Convolutional GANs for image generation.
-
Variational Autoencoders are generative models that use autoencoding to learn latent representations of data. It comprises an encoder network and a decoder network. The former compresses data into a latent space vector, while the latter reconstructs data from the latent vector. You should learn key VAE architectures like Recurrent VAEs, VQ-VAEs, and Convolutional VAEs.
