This paper investigates learning in a lifelong context. Lifelong learning addresses situations in which a learner faces a whole stream of learning tasks. Such scenarios provide the opportunity to transfer knowledge across multiple learning tasks, in order to generalize more accurately from less t...
本文介绍了一种可以学习多语言句子表示的方法,可用于30多个语种,93种语言and written in 28 different scripts.系统用了所有语言共享BPE词汇表的单BiLSTM 编码器,同时又在parallel corpora上训练的auxiliary解码器。这种技术允许我们只在英语上annotated data训练出的句子embedding模型的基础上训练分类器,然后迁移...
Bias occurs when a model has enough data but is not complex enough to capture the underlying relationships. As a result, the model consistently and systematically misrepresents the data, leading to low accuracy in prediction. This is known as underfitting.
Classification is about deciding which categories new instances belong to. For example we can organize objects based on whether they are square or round, or we might have data about different passengers on the Titanic like in project 0, and want to know whether or not each passenger survived. The...
In statistics, a quartile, a type of quantile, is three points that divide sorted data set into four equal groups (by count of numbers), each representing a fourth of the distributed sampled population. There are three quartiles: the first quartile (Q1), the second quartile (Q2), and the third qu...
Welcome to this lesson on using Jupyter notebooks.The notebook is a web application that allows you to combine explanatory text, math equations, code, and visualizations all in one easily sharable document. For example, here's one of my favorite notebooks shared recently, the analysis of gravitat...
AnacondaWelcome to this lesson on using Anaconda to manage packages and environments for use with Python. With Anaconda, it's simple to install the packages you'll often use in data science work. You'll also use it to create virtual environments that make working on multiple projects much less mi...
