Understanding AI
The field of artificial intelligence (AI) has grown rapidly in recent years and has become ubiquitous in many different aspects of modern life. AI is a software system that is based on neural networks, a technique that first began to be developed several decades ago but has recently become more powerful thanks to advances in computing resources. AI is being used to improve voice and image recognition, generate synthetic speech and imagery, and even browse the web. However, some people may be concerned about the idea of a rise of the machines and how AI could potentially become a threat. In this guide, we will explore the fundamental concepts of AI, key companies in the industry, and recent developments in the field.
The Basics: AI Concepts
Neural Network
Neural networks are artificial networks made up of interconnected cells called neurons that store and process information, similar to how the human brain functions. They can be used to create models that take input, process it, and produce an output.
Model
The model refers to the actual collection of code that accepts inputs and returns outputs. This can refer to any AI or machine learning construct, and sizes can depend on the system that it is used on. Models are created through a process called training.
Training
To create an AI model, a neural network is exposed to a dataset or corpus to create a statistical representation of the data. This is the most computation-intensive part and can take weeks or months on high-powered computers. Once the model is created, it can be run on smaller devices through a process called inference.
Inference
Inference is the process of the model actually doing its job and producing output through statistically connecting the input data. Big models still need to run on supercomputers and GPUs, but smaller ones can be run on smartphones or simpler devices.
Generative AI
Generative AI is an AI model that produces original output, such as an image or text. While these models can be impressive, it is important to remember that the output may not necessarily be true or reflect reality.
Important AI Terms
Large Language Model
Large language models (LLMs) are trained on text from the web and English literature, making them one of the most influential AI forms available today. LLMs can converse, answer questions in natural language, and imitate various styles of written documents. However, they are still pattern recognition engines and may not always reflect reality.
Foundation Model
Foundation models are large models trained from scratch on huge datasets, but can be trimmed down to fit smaller containers by reducing the number of parameters. These models require supercomputers to run, but can be fine-tuned using specialized datasets.
Key Companies in AI
Google is one of the largest and most important companies in AI, with a range of products and services that utilize AI, including Google Assistant, Google Translate, and Google Maps. Google is also a major contributor to AI research, with projects such as Google Brain.
Facebook is also heavily invested in AI, using it to improve its platform, create personalized recommendations, and detect fake news. Facebook has also developed tools such as PyTorch and Caffe2 to help researchers build AI models.
Microsoft
Microsoft has been exploring AI for decades and has developed a range of products and services that utilize the technology, such as Cortana, Bing, and Skype Translator. Microsoft also has a variety of research projects in AI, including Microsoft Research AI and Project Brainwave.
OpenAI
OpenAI is a research organization dedicated to creating safe and beneficial AI. It has developed several powerful language models, including GPT-3, and has contributed to research in fields such as robotics, healthcare, and gaming.
Recent AI Developments
GPT-3
Generative Pre-trained Transformer 3 (GPT-3) is one of the most powerful language models available, with 175 billion parameters. It has been used to generate original text, complete coding tasks, and even write entire articles. However, it has also faced criticism for generating unreliable or biased output.
Robotics
AI is increasingly being used in robotics, allowing machines to perform complex tasks and interact with humans more intelligently. Developments in robotics include self-driving cars, drones, and humanoid robots.
Conclusion
AI is an ever-expanding field with applications in many different areas of modern life. As developments in the technology continue to unfold, it is important to stay informed about key concepts, companies, and recent developments. This guide has provided an overview of the basics of AI, important companies in the industry, and recent developments to keep in mind.
