Topic 1 Question 111
An agricultural company is interested in using machine learning to detect specific types of weeds in a 100-acre grassland field. Currently, the company uses tractor-mounted cameras to capture multiple images of the field as 10 ֳ— 10 grids. The company also has a large training dataset that consists of annotated images of popular weed classes like broadleaf and non-broadleaf docks. The company wants to build a weed detection model that will detect specific types of weeds and the location of each type within the field. Once the model is ready, it will be hosted on Amazon SageMaker endpoints. The model will perform real-time inferencing using the images captured by the cameras. Which approach should a Machine Learning Specialist take to obtain accurate predictions?
Prepare the images in RecordIO format and upload them to Amazon S3. Use Amazon SageMaker to train, test, and validate the model using an image classification algorithm to categorize images into various weed classes.
Prepare the images in Apache Parquet format and upload them to Amazon S3. Use Amazon SageMaker to train, test, and validate the model using an object- detection single-shot multibox detector (SSD) algorithm.

C is my answer. Pay attention that the question is asking for 2 things:
- detect specific types of weeds
- detect the location of each type within the field.
Image Classification can only classify images. Object detection algorithm: 1.identifies all instances of objects within the image scene. 2.its location and scale in the image are indicated by a rectangular bounding box.
Data format for Computer Vision algorithms in SageMaker: Recommend to use RecordIO.

👍 3joep212021/09/25C is the right answer. you need to detect location
