Intelligence from Learnable Novelty
AI 中文解读
研究者提出了一种衡量“值得学习的新奇性”的新方法,并证明它能统一解释数据压缩、复杂系统计算和智能体探索等看似不相关的智能现象,为理解智能本质提供了全新视角。
简单来说,以往计算机学家常陷入两个极端:要么追求惊喜,结果被噪音吸引(比如盯着雪花屏发呆);要么规避一切意外,干脆缩在黑暗里。两者都混淆了“有用新知”和“无意义噪音”。这篇论文的核心贡献,是找到了一种叫“可学习新奇性”的量化指标——它能自动分辨哪些信息值得学,哪些只是随机干扰。研究者用极简单的算法(类似廉价计算芯片)就能估算它,并用它完成了三件大事:一是准确给不同复杂度的计算系统排名;二是让一个仿生神经网络自动学会生成孤立波(一种特殊能量结构);三是不靠任何人工标签,就让图像识别模型自己把数字图片分好类。把它作为奖励信号给强化学习AI,还能大幅提升它在多数游戏环境中的探索能力。
这项技术有望让AI自主学习能力大幅跃升。当下AI依赖海量标注数据,而未来机器人、自动驾驶或游戏AI可能无需人工干预,就能自行判断哪些环境信息是值得探索的“新知”,从而更快适应新场景、规避危险,甚至像人类一样在复杂世界中自主成长。

Abstract: Intelligence appears under different names in different fields: as data compression in statistics and machine learning, as universal computation in dynamical systems, and as adaptive behavior in agents. Each field carries its own objective, and the two most influential drives often fail in mirror image: novelty search, which seeks surprise, is transfixed by a noisy television screen, while the free-energy principle, which avoids surprise, is most content in a dark room. Both failures have a single cause: each objective treats as one quantity the surprise a learner can convert into knowledge and the surprise it never can. Here we show that the learnable part of that information, which we call learnable novelty, yields the seemingly disparate projections of intelligence, and we give a closed-form estimator of it built on a cheap and differentiable reservoir computer. Used as a measure, with no supervision of any kind, the estimator recovers decades of complexity classification, ranking the Turing-complete rule~110 highest among the elementary cellular automata. Used as an objective, its gradient carries a neural cellular automaton from simple dynamics into a regime of solitons, the traveling, colliding structures by which rule~110 computes, as well as organizes the representation of an image encoder around the ten digit classes of MNIST, fully unsupervised: no label ever enters training. Handed to a reinforcement-learning agent as an intrinsic reward, it supplies the exploration that task rewards lack, improving on the task baseline in nine of ten environments and collapsing in none. Complexity generation, abstraction, and exploration, ordinarily pursued with unrelated objectives in separate fields, thus emerge from ascent on one differentiable quantity, and the projections of intelligence gain a common quantitative footing.
