The pretext task
Webb29 aug. 2024 · The main problem with such an approach is the fact that such a pretext task could lead to focusing only on buildings and other high, man-made (usual steel) objects and their shadows. The task itself requires imagery containing high objects and it is difficult even for human operators to deduce from the imagery. An example is shown in … Webb5 apr. 2024 · The jigsaw puzzle pretext task is formulated as a 1000-way classification task, optimized using the cross-entropy loss.

Webbpretext task confide in the heuristics of designing the pretext task that limits the generalization of learned representations. The discriminative approach in the form of contrastive learning is utilized to learn the latent representation to overcome the heuristics of pretext tasks [14] [15].
