Everyday life depends on ritual performances such as being polite, dressing appropriately, following proper procedure and observing the law. The particulars vary, often mightily, across time, space and societies. But they are the foundation of all formal and informal institutions,…
Source: Live Mint All these things are powered by artificial-intelligence (AI) models. Most rely on a neural network, trained on massive amounts of information—text, images and the like—relevant to how it will be used. Through much trial and error the weights of connections between simulated neurons are tuned on the basis of these data, akin…
Source: Live Mint Large language models have a keen appetite for electricity. The energy used to train OpenAI’s gpt-4 model could have powered 50 American homes for a century. And as models get bigger, costs rise rapidly. By one estimate, today’s biggest models cost $100m to train; the next generation could cost $1bn, and the…
Source: Live Mint LLMs are built using a technique called deep learning, in which a network of billions of neurons, simulated in software and modelled on the structure of the human brain, is exposed to trillions of examples of something to discover inherent patterns. Trained on text strings, LLMs can hold conversations, generate text in…
Source: Live Mint Silicon Valley’s tech bros are having a difficult few weeks. A growing number of investors worry that artificial intelligence (AI) will not deliver the vast profits they seek. Since peaking last month the share prices of Western firms driving the AI revolution have dropped by 15%. A growing number of observers now…
