1.认识goole audio set(引用一个Google数据集audio set 使用教程

数据集的两种形式:

1:描述每个片段的文本(csv)文件,包括YouTube视频ID、开始时间、结束时间和一个或多个标签。

2:   TensorFlow Record 文件,称为feature dataset,frame-level features are stored as tensorflow.SequenceExample protocol buffers,这个

原型被以文本的形式给出:

context: {
  feature: {
    key  : "video_id"
    value: {
      bytes_list: {
        value: [YouTube video id string]
      }
    }
  }
  feature: {
    key  : "start_time_seconds"
    value: {
      float_list: {
        value: 6.0
      }
    }
  }
  feature: {
    key  : "end_time_seconds"
    value: {
      float_list: {
        value: 16.0
      }
    }
  }
  feature: {
    key  : "labels"
      value: {
        int64_list: {
          value: [1, 522, 11, 172] # The meaning of the labels can be found here.
        }
      }
    }
}
feature_lists: {
  feature_list: {
    key  : "audio_embedding"
    value: {
      feature: {
        bytes_list: {
          value: [128 8bit quantized features]
        }
      }
      feature: {
        bytes_list: {
          value: [128 8bit quantized features]
        }
      }
    }
    ... # Repeated for every second of the segment
  }

}
