我正在尝试使用spaCy创建一个新的实体分类'Species',其中包含物种名称列表,例如,他可以在这里找到.

我从这个spaCy教程(这里是 Github代码)中找到了一个培训新实体类型的教程.然而,问题是,我不想为每个物种名称手动创建一个句子,因为它会非常耗时.

我在下面创建了训练数据,如下所示:

TRAIN_DATA = [('Bombina',{'entities':[(0,6,'SPECIES')]}),
 ('Dermaptera',{'entities':[(0,9,'SPECIES')]}),
  .... 
]

我创建训练集的方式是:不是提供完整的句子和匹配实体的位置,而是仅提供每个物种的名称,并以编程方式生成开始和结束索引:

[(0,6,'种类')]

[(0,9,'种类')]

训练代码下面是我用来训练模型的.(从上面的超链接复制的代码)

nlp = spacy.blank('en')  # create blank Language class

 # Add entity recognizer to model if it's not in the pipeline 
 # nlp.create_pipe works for built-ins that are registered with spaCy 
 if 'ner' not in nlp.pipe_names: 
     ner = nlp.create_pipe('ner') 
     nlp.add_pipe(ner) 
 # otherwise, get it, so we can add labels to it 
 else: 
     ner = nlp.get_pipe('ner') 

 ner.add_label(LABEL)   # add …

在我的项目中,我需要每分钟自动拍照.但我找不到任何解决方案.

这是我实现的代码,但它不起作用......

我使用NSTimer调用相机每4秒拍照.我只需要这个东西

//This method is all for the time setup. You can ignore it.

-(NSDate *)userInfo {

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

[dateFormatter setDateFormat:@"yyyy-MM-dd 'at' HH:mm:ss"];

NSDate *date = [[[NSDate alloc]init]autorelease];

NSString *formattedDateString = [dateFormatter stringFromDate:date];

NSLog(@"formattedDateString: %@", formattedDateString);   

return date;    
}


- (void)targetMethod:(NSTimer *)theTimer {
   NSDate *startDate = [self userInfo];

   //newly changed lines.
   UIImagePickerController *myPicker;
   [myPicker takePicture];
   NSLog(@"Timer started on %@", startDate);

}


- (IBAction) showCameraUI {


   [NSTimer scheduledTimerWithTimeInterval:4.0
                                 target:self
                               selector: @selector(targetMethod:)
                               userInfo:[self userInfo]
                                repeats:YES];

}

我是objective-c的新手,我在UIImagePickerControllerMediaMetaData中读取信息时遇到问题.

-(void) imagePickerController:(UIImagePickerController *)imagepicker didFinishPickingMediaWithInfo:(NSDictionary *)info {

//This line is fine.
NSDictionary *metadata = [info objectForKey:UIImagePickerControllerMediaMetadata];

//This line fail to operate...
NSArray *tiffData = [metadata objectForKey:Exif];

我可以获取元数据.但是,元数据中的信息有点令人困惑,下面显示了内部元数据.

UIImagePickerControllerMediaMetadata =     {
    DPIHeight = 72;
    DPIWidth = 72;
    Orientation = 6;
    "{Exif}" =         {
        ApertureValue = "2.526068811667588";
        BrightnessValue = "-1.739497174308802";
        ColorSpace = 1;
        DateTimeDigitized = "2012:02:21 11:53:44";
        DateTimeOriginal = "2012:02:21 11:53:44";
        ExposureMode = 0;
        ExposureProgram = 2;
        ExposureTime = "0.06666666666666667";
        FNumber = "2.4";
        Flash = 32;
        FocalLenIn35mmFilm = 32;
        FocalLength = "2.03"; …

我有两个不同处理方法收集的两个数据样本:

sam.a <- c( 0.1333333, 0.2258065, 0.1944444, 0.2894737)
sam.b <- c(0.137931, 0.093750, 0, 0)

我首先在R中尝试了t.test:

t.test(sam.a,sam.b)

这给了我如下结果(p < 0.05):

    Welch Two Sample t-test

data:  sam.a and sam.b
t = -4.1497, df = 5.8602, p-value = 0.006329
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:
 -0.27151717 -0.06935361
sample estimates:
mean of x mean of y 
0.1994576 0.3698930 

当我在R中使用anova尝试相同的数据时:

aov(sam.a ~ sam.b)

结果变得微不足道(p > 0.05):

            Df   Sum Sq  Mean Sq F …
