The Simplified Guide: Breaking Down AI Buzzwords

Here's some language you may be coming across a lot these days: machine learning, deep learning, foundation models, large language models, generative AI? They often leave us in a whirlwind of questions. What do these things mean? More importantly, how are they all connected? Let's clear up the confusion and put these terms into perspective.

Firstly, all these terms stem from a single root – Artificial Intelligence (AI). AI is all about introducing human-like intelligence to machines, allowing them to perform tasks that would typically require human brainstorming. This concept isn't new; it has been with us for quite some time, perhaps popping up in your mind with the example of Eliza, a chatbot designed in the 1960s to imitate human conversation.

Machine Learning (ML), a branch of AI, adds more flavor. It develops computer algorithms to learn from and make decisions based on data, instead of just following pre-set instructions. The idea is to let computers learn patterns in data and make predictions or decisions, all on their own. But mind you, ML is no small term. It houses categories like supervised learning (learning from labeled data), unsupervised learning (discovering patterns without predefined labels), and reinforcement learning (learning by feedback from interactions with environment).

While we're discussing ML, let's touch upon its subset—the increasingly popular Deep Learning (DL). DL is all about artificial neural networks with multiple layers, hence the 'deep'. It shines when dealing with heaps of unstructured data (like images or regular text) and identifying complex patterns within them. But remember, not all ML is about DL. There are still traditional ML methods (think linear regression, decision trees, etc.) that are quite significant.

Any talk of DL would be incomplete without mentioning Foundation Models. Riding the DL bandwagon, they are large-scale neural networks trained on enormous amounts of data. The aim of these models is to act as a foundational base for numerous applications. Rather than creating a model manually for every task, you can fine-tune a pre-existing foundation model, saving time and resources. They are adaptable and scalable, bringing a new trend in AI solutions. You can find a lot of these models on https://huggingface.co/, but watch out not all models are licenced to be used in commercial products.

An important subtype of foundation models are the Large Language Models (LLMs). LLMs specialize in processing and interpreting text in human-like ways. The 'large' in LLMs refers to the scale—these models possess billions of parameters, providing depth to their capabilities. They interact using human languages understanding grammar, idioms, context, and sometimes even cultural nuances. LLMs can answer questions, translate languages and even creatively write, much like this blog post you're reading.

Apart from text, Foundation Models also embrace other domains. Vision models interpret and generate images, scientific models predict complex biological structures, and audio models could generate a catchy school anthem or even the next best-selling song!

Lastly, let's explore Generative AI. These are crafted to generate new content, using the knowledge harnessed from foundation models. Think of Generative AI as the creative artist in the AI world, bringing forth original and innovative outputs.

So, there you have it! We've taken a rollercoaster ride through the galaxy of AI. Hopefully, we've made sense of some complex terms by simplifying heavyweight AI jargon into something more digestible.
