今天有空,就来研究下它~ 论文地址:https://github.com/RasaHQ/DIET-paper 1. 简介 先总结下DIET出彩的地方: DIET是一种用于意图分类和实体识别的多任务体系结构。 3.3 与finetuning BERT 比较 将 可进行finetuning Bert的DIET 与 sparse特征+冻结预训练ConveRT Emb的 DIET进行比较: 可以看到,sparse 特征+冻结预训练ConveRT Emb的 DIET在实体识别上表现优于fine-tuned BERT的DIET,而在意图分类方面表现持平。 但要知道,在所有 10 个 NLU-Benchmark 数据集上**,finetuning的 DIET 中的 BERT 需要 60 个小时,而使用 ConveRT 嵌入和稀疏特征的 DIET 只需要 10

例如,你可能想把热量不到400卡路里的菜分为“低热量”(diet),热量400到700卡路里的菜为“普通”(normal),高于700卡路里的菜为“高热量”(fat)。 由于 Dish 类 没有把这个操作写成一个方法,你无法使用方法引用,但你可以把这个逻辑写成Lambda表达式: public enum CaloricLevel { DIET, NORMAL, =[chicken], NORMAL=[beef]}, OTHER={DIET=[rice, season fruit], NORMAL=[french fries, pizza]}, FISH={DIET ], OTHER=[NORMAL, DIET], FISH=[NORMAL, DIET]} 传递给映? , NORMAL], OTHER=[DIET, NORMAL], MEAT=[DIET, FAT, NORMAL]} ---- 附 public static List<Dish> menu
核心方法 研究者们开发了一个名为Genome-on-Diet的框架,它是首个高度并行、内存节省且准确的稀疏基因组序列处理框架。 读段映射 Genome-on-Diet在读段映射任务中表现出色。 微生物组分类分析 在分类分析任务中,Genome-on-Diet能够提供更快、更节省存储空间的分类分析。 这使得Genome-on-Diet在处理宏基因组样本时具有更高的效率和准确性。 挑战 尽管稀疏化基因组学在加速基因组分析方面表现出色,但它也面临一些挑战。 Genome-on-Diet框架的提出,为基因组分析提供了一种全新的解决方案,它在读段映射、包含搜索和分类分析等任务中均展现出了显著的性能提升和存储效率优势。
dataset, which comes with ggplot2 # First plot p1 <- ggplot(ChickWeight, aes(x=Time, y=weight, colour=Diet curve for individual chicks") # Second plot p2 <- ggplot(ChickWeight, aes(x=Time, y=weight, colour=Diet )) + geom_point(alpha=.3) + geom_smooth(alpha=.2, size=1) + ggtitle("Fitted growth curve per diet () + ggtitle("Final weight, by diet") # Fourth plot p4 <- ggplot(subset(ChickWeight, Time==21), aes (x=weight, fill=Diet)) + geom_histogram(colour="black", binwidth=50) + facet_grid(Diet ~ .) + ggtitle

我们也可以自定义分组规则,比如按照卡路里的高低分为高热量,正常和低热量: 首先定义一个卡路里高低的枚举类型 public enum CaloricLevel { DIET, NORMAL, FAT }; else return CaloricLevel.FAT; }) ); System.out.println(dishesByCalories); 输出结果:{DIET =[prawns], NORMAL=[salmon]}, OTHER={DIET=[rice, season fruit], NORMAL=[french fries, pizza]}, MEAT={DIET mapping( d -> { if (d.getCalories() <= 400) return CaloricLevel.DIET 输出结果:{FISH=[DIET, NORMAL], MEAT=[DIET, NORMAL, FAT], OTHER=[DIET, NORMAL]}。 分区 分区类似于分组,只不过分区最多两种结果。
