ValueError: Perplexity must be less than n_samples # 解决方案: 确保perplexity参数小于样本数量 1. 2. RuntimeError: The requested operation could not be performed # 解决方案: 检查数据预处理是否正确,确保数据格式符合要求 1. 2. 最佳实践 在使用t-SN
High-dimensional datasets can be very difficult to visualize. While data in two or three dimensions can be plotted to show the inherent structure of the data, equivalent high-dimensional plots are much less intuitive. To aid visualization of the structure of a dataset, the dimension must be red...

TextAttack is model-agnostic - meaning it can run attacks on models implemented in any deep learning framework. Model objects must be able to take a string (or list of strings) and return an output that can be processed by the goal function. For example, machine translation models take a ...
--n_iteris the total number of iterations. If running in opt-SNE mode this argument is used to stop the run if opt-SNE has not already done so by this point. --perpis perplexity. --thetais theta (aka "angle"). --optsneis a flag with no accompanying value. If this flag if prese...
