Discovery of Linear Acyclic Models Using Independent Component AnalysisShiga University, RIKEN
?
This document discusses the discovery of linear acyclic models from non-experimental data using independent component analysis (ICA). It describes how existing methods assume Gaussian disturbances, producing equivalent models, whereas the proposed LiNGAM approach assumes non-Gaussian disturbances. This allows identifying the connection strengths and structure without equivalent models. The LiNGAM algorithm estimates the matrix B using ICA and post-processing, finds a causal order, and prunes non-significant edges. Examples show LiNGAM can correctly estimate networks and the document concludes it is an important topic with code available online.
This document summarizes a research paper on scaling laws for neural language models. Some key findings of the paper include:
- Language model performance depends strongly on model scale and weakly on model shape. With enough compute and data, performance scales as a power law of parameters, compute, and data.
- Overfitting is universal, with penalties depending on the ratio of parameters to data.
- Large models have higher sample efficiency and can reach the same performance levels with less optimization steps and data points.
- The paper motivated subsequent work by OpenAI on applying scaling laws to other domains like computer vision and developing increasingly large language models like GPT-3.
