In this tutorial, we’re going to explore the differences and nuances of transfer learning and domain adaptation. Transfer learning is a broad term that describes using the knowledge gained from one machine learning problem in another one. Domain adaptation describes a special case of transfer learning that only covers the change of the data domain.
To clarify transfer learning, we compare it to a classical supervised machine learning problem.For a better understanding, we work with a sample dataset of dog and cat pictures.
Transfer Learning describes a collection of machine learning techniques that work with a structure similar to the classical supervised case.In contrast, it can also work with datasets and features that are vastly different.
In domain adaptation, we can look a bit closer at pragmatic approaches. This lies in the fact, that only changing the dataset makes it much easier to tune our model for our new machine learning process.
As we have seen transfer learning offers a range of methods to use an already existing machine learning model in a new environment. In the special case of domain adaptation, we have an issue frequently encountered in a real-world scenario, a distinct dataset. For this case the divergence-based domain and domain adaptation and the iterative approach...
May 19, 2021 · Oftentimes we don’t have enough data to train a deep learning model for a problem, but we can use transfer learning or domain adaptation strategies to adapt a model from a different but related ...
This led to memory transfer experiments in the 1970's wherein an animal was taught something, like a conditioned response to a signal, and then killed, and its brain ground up in a malt mixer; the liquid brain was centrifuged to extract brain proteins or RNA molecules, which were then injected into the brains of untrained recipient animals.
This implies that the brain must hold an ongoing representation or neural model of a current situation and must respond to any mismatch between that ongoing memory and the current stimulus situation (see chapter on Intelligence, Cognition, and Language). This is a very adaptive property of the brain's functioning.
The concept of adaptive memory and learning has two defining assumptions: First, the capacity to preserve and recover information over time is adaptive, meaning that the systems that enable memory and learning are goal-directed and functionally designed. Rather than domain-general, operating the same regardless of input and domain, species’ retention systems are “tuned” to solve ...

Nov 11, 2023 · Equilibrium . The process of assimilation and accommodation is continuous and dynamic, as we engage with a changing and evolving environment. However, in between the ongoing work of assimilation and accommodation, there are moments where our existing schemas match the circumstances, and we are able to understand everything in our environment.
