Which machine learning approach fulfills the company’s long-term needs?
Convert the images to grayscale and retrain the model
Reduce the number of distinct items from 10 to 2, build the model, and iterate
Attach different colored labels to each item, take the images again, and build the model
Augment training data for each item using image variants like inversions and translations, build the model, and iterate.
Explanations:
Converting images to grayscale may reduce the amount of information available for the model, which is unlikely to improve performance, especially with complex image data. It would not address the core issue of insufficient training data.
Reducing the number of items from 10 to 2 would limit the diversity of the training data and may not be an effective long-term solution. It may simplify the model, but it doesn’t help with the issue of poor performance across multiple items.
Adding colored labels could potentially introduce noise in the images, making it harder for the model to learn relevant features of the items. It would also require retaking the images, which is inefficient and doesn’t solve the core problem of insufficient labeled data.
Augmenting the training data with transformations like inversions and translations increases the variety and volume of data, helping the model generalize better. This approach is commonly used to improve performance when data is limited and can be iteratively improved.
Based on what I know, the answer is:
Augment training data for each item using image variants like inversions and translations, build the model, and iterate.
