Batch and Continuous Bioreactors

2023
Bioreactors are used to grow organisms in large volumes, thereby enabling the production of mass quantities of the target product. These reactors can be batch reactors, which contain all of the components needed for cell growth, or continuous reactors, which have inlet and outlet ports allowing for the addition of fresh growth media and the removal of cell waste. This video presents batch and continuous reactors and demonstrates the use of bioreactors to grow bacteria in the laboratory.

An Introduction to Learning and Memory
0 Views •
2023
Learning is the process of acquiring new information and memory is the retention or storage of that information. Different types of learning, such as non-associative and associative learning, and different types of memory, such as long-term and short-term memory, have been associated with human behaviors. Studying these components in detail helps behavioral scientists understand the neural mechanisms behind these two complex phenomena. JoVE's overview on learning and memory introduces common...

Visual Statistical Learning

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University The visual environment contains massive amounts of information involving the relations between objects in space and time; certain objects are more likely to appear in the vicinity of other objects. Learning these regularities can support a wide array of visual processing, including object recognition. Unsurprisingly, then, humans appear to learn these regularities automatically, quickly, and without conscious awareness. The name...

Continuity of a Function

2025
A function is continuous at a point a if three conditions are met: the function is defined at a, the limit of the function as x approaches a exists, and this limit equals the function’s value. Mathematically, this is written asThis definition ensures the graph of the function does not exhibit any breaks, holes, or jumps at that point. Discontinuities occur when any of these conditions fail. A removable discontinuity exists when the two-sided limit exists but the function is either undefined or...

The model uses plasticity to incorporate information from new tasks or changing data streams, while stability preserves capabilities learned earlier. Excessive plasticity can overwrite established knowledge, whereas excessive stability can prevent useful adaptation. This balance matters in engineering systems because robots, vehicles, and monitoring platforms must respond to new conditions without losing performance on situations they already learned to handle.
These strategies protect earlier knowledge through different mechanisms. Rehearsal or replay revisits previously learned information, regularization limits damaging parameter changes, parameter isolation separates some knowledge from later updates, and knowledge distillation transfers earlier capabilities into the updated model. Selecting among them depends on how the system must preserve prior behavior while learning from new tasks or data.
Incremental updates allow a model to incorporate incoming tasks or data without requiring complete retraining after every change. This supports operation in environments where information arrives sequentially. However, each update can affect previously acquired capabilities, so the update process must be paired with a forgetting-control strategy to maintain a useful balance between adaptation and retention.
A typical workflow presents the model with a sequence of tasks or data streams, updates its parameters as new information arrives, and applies a forgetting-control approach during those updates. The system then needs to consider both newly acquired performance and retention of earlier capabilities. This workflow is suited to operational settings where conditions evolve after deployment.
Engineers may choose continual learning when a system must adapt to changing conditions over time and cannot rely on complete retraining for every new situation. The approach is especially relevant to deployed systems that encounter sequential information, such as autonomous vehicles, adaptive robots, predictive-maintenance tools, and monitoring systems. Its value comes from combining adaptation with preservation of earlier knowledge.
In engineering, continual learning supports systems that face evolving operating conditions. Adaptive robots can incorporate new situations, autonomous vehicles can respond to changing environments, and predictive-maintenance or monitoring systems can update their learned behavior as conditions develop. Across these applications, the central outcome is an ability to accommodate new information while retaining previously acquired capabilities rather than discarding them.
