AI Concepts Made Easy: A Beginner's Manual (Part 2 of 5)
In the previous article, we discussed the capabilities of artificial intelligence (AI) and machine learning to analyze data, identify patterns, and make predictions. Now, let’s explore some more advanced techniques powering AI's continued evolution: deep learning, neural networks, and generative models.
Deep learning has become dominant in recent years, achieving state-of-the-art1 results in computer vision, natural language processing, and other complex tasks like speech recognition, drug discovery, game playing, and medical diagnosis.
Deep learning is based on artificial neural networks that work like the neurons in the human brain. The neural networks are made up of mathematical functions arranged in layers. Information flows between these layers, just as it flows between neurons in the brain. With enough layers, deep learning systems can analyze data in very complex ways. This neural network structure lets deep learning perform well on tasks like recognizing patterns, making predictions, and understanding language.
These neural nets allow deep learning models to learn hierarchical feature representations from data. For example, early layers may learn to recognize edges, while deeper layers combine edges into shapes, objects, and complex patterns. This layered feature learning is what enables deep learning to master perception tasks that have been difficult for traditional machine learning algorithms. With massive datasets and immense computing power from GPUs2, the capabilities of deep learning models have rapidly advanced over the last decade.

To make these deep neural networks learn, we show them lots of examples and tell them the correct answers. They use a special process called backpropagation to adjust the connections between the neurons, making them better at giving the right answers. Deep neural networks have been really successful in many areas, like recognizing objects in pictures, understanding and talking in human language, and even suggesting things we might like.
Deep learning is very good at difficult tasks like recognizing images, understanding speech, translating languages, and predicting outcomes. It can find complex patterns that normal software cannot. But deep learning needs huge amounts of data and computing power to work well. It can also pick up biases if the data is unbalanced. People still need to train, monitor and test these systems. When used properly though, deep learning allows new possibilities that old-fashioned software cannot.
So in simple terms, deep learning brings out the amazing capabilities of artificial intelligence by mimicking the neural networks in our minds. These neural networks allow deep learning models to continuously learn complex concepts from data, similar to how we acquire knowledge.
While deep learning has achieved incredible perception abilities, matching and even exceeding human vision and language understanding, it lacks a creative spark that is fundamental to the human mind. Deep learning models can analyze data and classify patterns, but cannot create novel ideas from scratch. This is the gap that generative AI aims to fill.
Generative AI refers to techniques like large language models (LLM’s) that can produce original text, images, audio and more from scratch. Tools like GPT-3 and DALL-E 2 display remarkable creativity in generating human-like writing and art given just a starting prompt. Generative AI opens up new possibilities to explore the realm of human imagination and innovation.
Comparing Machine Learning, Deep Learning and Generative AI
While deep learning and generative AI are both advanced forms of machine learning, there are some key differences:
- Machine learning uses algorithms to find patterns and make predictions from data. Deep learning learns complex representations from data without extensive programming.
- Machine learning is generally supervised - it requires humans to label and prepare training data. Deep learning is more unsupervised and learns directly from unlabeled data.
- Generative AI focuses on creating novel content versus analyzing data for insights. It aims to mimic human creativity versus basic prediction.
- Deep learning excels at perception tasks like computer vision. Generative AI specializes in production tasks like writing and image generation.
When considering which approach to use, it depends on the specific use case and data available. For analytical tasks, machine learning or deep learning may be preferred. For creative applications, generative AI offers more possibilities.

As AI technologies continue advancing, the possibilities for highly capable yet ethical and safe AI systems are expanding. Different AI approaches have complementary strengths - deep learning excels at analysis while generative models power creativity. By combining these capabilities, future AI assistants could collaborate with humans in transformative new ways.
Product managers oversee the development of new products. Traditionally, they did all the analytical work like data analysis themselves. Now AI tools can automate these analytical tasks by processing customer data. This allows product managers to focus on big picture strategy and creative problem solving. AI handles the analytics, while the managers apply their leadership and imagination. Together, AI and human intelligence complement each other to create better products faster.
