Artificial intelligence (AI) has been a hot topic since the public has witnessed the incredible potential and creativity of OpenAI’s GPT, Meta’s LLama, Anthropic’s Claude, and Google’s Gemini, to name a few. All these unique models further prove that AI is not just one technology. Rather, it describes a broad range of technologies that can learn, reason, and solve problems. These AI systems are made up of complex algorithms and mathematical functions, but at the root of it all is data, data, and more data. The higher quality data, the larger the datasets, and the more diverse the data, the faster and more accurate these AI systems will be.
Three Types of Artificial Intelligence
AI can be categorized into several types, each serving different purposes:
- Artificial Narrow Intelligence (Weak AI): This is the most common form of AI we see today, as these are systems designed for specific tasks. Examples include:
- Voice Assistants: Siri and Alexa can perform tasks such as setting reminders, answering questions, and controlling smart home devices.
- Recommendation Systems: Netflix and Amazon analyze user behavior and suggest movies, shows, or products based on past preferences.
- Artificial General Intelligence (AGI): Similar to humans, this form of AI can understand, learn, and apply intelligence across a broad range of tasks. While true general AI has not yet been achieved, ongoing research aims to develop systems that can adapt to various challenges.
- Artificial Super Intelligence (ASI): This form of AI. that would surpass human intelligence across all fields remains a topic of debate and exploration in the AI community, but it is safe to say we aren’t remotely close to achieving this yet.
Four Categories of Core AI Components
The core components of AI can be broken down into four categories:
- Machine Learning (ML): A subset of AI focused on algorithms that allow computers to learn from data. Examples include:
- Image Recognition: Google Photos uses ML to identify and categorize images based on the content within them. It works well but is constantly improving.
- Spam Detection: Gmail uses ML algorithms to classify incoming emails as spam or not based on patterns. I wish there was a way to do this with snail mail!
- Natural Language Processing (NLP): This capability enables machines to understand and interpret human language. Examples include:
- Language Translation: Google Translate engages NLP to convert text from one language to another. Makes traveling more fun.
- Chatbots: Customer service bots on websites can interact with users to answer questions and resolve issues. Some are better than others, of course.
- Computer Vision: AI that enables machines to interpret and make decisions based on visual data. Examples include:
- Medical Imaging: AI systems analyze MRIs and x-rays to assist in diagnosing medical conditions. We see this in retinal imaging as well.
- Autonomous Vehicles: Self-driving cars use computer vision to identify objects, lanes, and traffic signals for safe navigation. In today’s world, Tesla leads all other manufacturers in this capability.
- Deep Learning: A specialized area of ML that employs neural networks with many layers to process data. Examples include:
- Speech Recognition: Apple’s Siri utilizes deep learning to understand and process spoken language.
- Facial Recognition: Facebook uses deep learning to identify and automatically tag individuals in photos.
Various Forms of Input Provide the Data AI Requires
AI systems require an input or prompt to provide the machine direction and clarity on what output to produce. This input can take various forms such as text or images. The machine processes this information and provides an output or response. For instance, text input can be analyzed to generate meaningful responses in NLP.
Moreover, in computer vision, image input can be interpreted to recognize objects or patterns. This is how AI can accurately detect an animal species based on a picture. It starts to identify patterns with eyes, nose, fur, and size. The output or best suggested response can also be in the form of an image or text, depending on what is asked for in the input or prompt. The more data these machines learn from or train on, the more accurate the output will be. Here are some examples:
- Text: One may type into a chatbot, “What are the store hours today?”
- The AI processes this natural language prompt or input, understands the context, and retrieves the relevant information to provide an accurate response, such as, “They are open from 9 a.m. to 9 p.m. today.”
- Audio: In voice recognition, spoken inputs or prompts are converted into text through NLP. One may say, “play music,” for example.
- The AI machine interprets the text to perform the action of playing music.
- Image: In facial recognition, one may upload a photo.
- The system analyzes the features of the face, comparing them against a database of everything it knows, and produces an output indicating whether there is a match.
High-Quality Input Leads to the Best AI Models
We must keep in mind that these AI systems are only as good as the data they are trained on. If a system is fed quality data, it will provide more accurate results. Conversely, if it is fed poor data, it becomes prone to mistakes and can create biases in its outputs. All AI models are trained on data, so this point underscores the importance of data quality in developing efficient AI systems. The quality, quantity, and diversity of data directly influences accuracy and reliability.
High-quality, well-structured, and relevant data lead to the best AI models. For example, an AI system designed to diagnose diseases must be trained on comprehensive data of medical images to accurately identify conditions. If the data includes poor quality images or irrelevant and outdated information, the AI may produce incorrect diagnoses.
Moreover, these models require large datasets to identify patterns effectively. For example, a self-driving car needs vast amounts of driving data during the day, night, rain, and snow to learn how to navigate safely.
Additionally, a diverse dataset helps moderate bias. If we want an AI model to accurately diagnose disease for any demographic, it should not be trained on only one group of people. Some facial recognition systems have faced backlash for being inaccurate for individuals with specific skin tones due to the lack of diversity in training datasets. All to say, bias in training data can lead to biased outputs, which is why there needs to be thorough data audits in AI training datasets.
What Are the Ethics Behind AI?
As one can imagine, the rise of AI brings several ethical concerns along with it. Some of these concerns include:
- Bias and Errors: AI systems can preserve existing biases, leading to unfair outcomes.
- Legal Risks, Privacy, and Consent: The collection and analysis of large public datasets raises concerns about individual privacy and who truly owns what.
- Job Displacement: Automation may lead to a loss of jobs in certain sectors, but it will also create opportunities for new jobs.
It is safe to say Artificial Intelligence is transforming how we live and work, with its applications touching nearly every aspect of our lives. The future of AI holds immense potential. As AI systems become more integrated into workplaces, the focus will shift to collaboration between humans and machines to enhance productivity. This is particularly useful in health care as it allows doctors to deliver better care with empathy instead of being data collectors. As I always say, AI is the greatest accelerator the world has witnessed.
