介绍：

除了深度学习之外，近期机器学习领域的一个热点是probabilistic program induction。本次语言、逻辑、认知、计算论坛（LLCC）将围绕这一新工作展开讨论。如果大家对AlphaGo背后的深度学习以及蒙特卡洛树搜索感兴趣也欢迎参加，可以与吴玺宏老师讨论。



Abstract: People learning new concepts can often generalize successfully from just a single example, yet machine learning algorithms typically require tens or hundreds of examples to perform with similar accuracy.



In December last year a paper titled “Human-level concept learning through probabilistic program induction” by Lake et. al. was published as a Science cover story. In this paper, the author presented a computational model that captures some concept learning abilities of human in handwritten characters. The so-called hierarchical bayesian program learning (HBPL) model represents concepts as simple programs that best explain observed examples under a Bayesian criterion. On a challenging one-shot classification task, the model achieves human-level performance while outperforming recent deep learning approaches.
