Recent breakthroughs in artificial intelligence (AI) have been driven by substantial increases in model scale enabled by computational advances. However, the vast data requirements of large neural network models raise critical questions around copyright compliance and attribution norms. In this paper, we analyze the copyright risks emerging from current AI training paradigms and present recommendations for responsible practice. AI Models Require Massive Training Data Most leading AI systems employ a transfer learning technique for model development. Models such as DALL-E 2, GPT-3, and Stable Diffusion are first pre-trained on large corpora of text, images, audio, video and other data scraped from publicly available sources. For instance, GPT-3 was trained on hundreds of billions of text tokens from books, Wikipedia articles, and webpages. Unsupervised pre-training objectives teach the models to encode generalized data representations across modalities...

What is Generative AI? Generative AI refers to machine learning techniques that allow computers to synthetically create new content like images, videos, text and audio. The most popular forms used for visual media generation include: Generative Adversarial Networks (GANs) - Two neural networks contest to generate increasingly realistic outputs. Variational Autoencoders (VAEs) - Learn compressed data representations to reconstruct new samples. Diffusion Models - Iteratively add structured noise to create outputs. These AI systems can produce remarkably realistic and diverse images from text prompts. Leading services like DALL-E 2 , Midjourney and Stable Diffusion leverage versions of these algorithms. For digital artists and bloggers, generative AI presents exciting new creative possibilities. Let's look at 18 top options: 1. DALL-E 2 (Free Limited Trial) DALL-E 2 is one of the most advanced generative A...

Conversational AI Powers and Limitations: Recent strides in natural language processing have been driven by a technique called transfer learning. Large transformer-based neural networks are first trained or “pre-trained” on massive text datasets. The models learn general linguistic patterns this way. Then the models are fine-tuned on more specialized conversational datasets to optimize chat abilities. Claude 2 and ChatGPT 4 exemplify this approach. Anthropic pre-trained Claude on internet common sense data specifically curated to minimize toxicity. OpenAI trained GPT-4 on both internet data and human AI tutor conversations. The results are remarkably eloquent bots. However, their knowledge comes entirely from training datasets, not lived experience. Neither bot truly comprehends language or the world. They engage based on statistical patterns between words. Despite claims of “understanding context”, the bots have no real-world grounding for their words. This reliance on dat...

Barcelona is emerging as a leading hub for artificial intelligence research and development. Recent advances in generative AI are creating excitement in Barcelona's academic and startup communities. In this post, we'll explore how Barcelona researchers are pushing the boundaries of generative AI - systems capable of creating original digital content. What is Generative AI? Generative AI refers to machine learning techniques that allow computers to generate new content like images, videos, text and audio. The most popular forms today include: Generative adversarial networks (GANs) - Two neural networks contest with each other to generate increasingly realistic outputs. Variational autoencoders (VAEs) - Neural nets that learn compressed representations of data to generate new samples. Diffusion models - Generate content by iteratively revising noise into more structured outputs. Reinforcement learning - Guides AI agents via rewards to create content that maximizes g...

Artificial intelligence (AI) is rapidly transforming the way businesses interact with their customers. By using AI to collect and analyze data, businesses can gain a deeper understanding of their customers' needs and preferences. This information can then be used to personalize the customer experience in a variety of ways, from recommending products to providing customer service. What is Personalized Customer Experience? Personalized customer experience (CX) is the process of tailoring the customer's experience with a brand to their individual needs and preferences. This can be done through a variety of channels, including website, mobile app, social media, and in-store. How Does AI Personalize the Customer Experience? AI can be used to personalize the customer experience in a variety of ways, including: Recommending products: AI can be used to analyze a customer's past purchases, browsing history, and social media activity to recommend products that they are likel...

What is Synthetic Data? Synthetic data is artificial data that is created to mimic real-world data. It is often used in machine learning projects to train models that can be used to make predictions or decisions in a variety of industries. There are a number of reasons why synthetic data is becoming increasingly popular in machine learning projects. First, it can be used to train models on data that is difficult or expensive to collect in the real world. For example, a company that wants to develop a model to predict customer churn might not have access to enough real-world data to train the model effectively. In this case, the company could use synthetic data to create a larger and more diverse dataset that can be used to train the model. Second, synthetic data can be used to address privacy concerns. In some cases, companies may not be able to share real-world data with third-party organizations, such as machine learning providers. In this case, the company could use syntheti...
