The 1-vs-2 cycles conjecture or 2-cycle conjecture is an unproven computational hardness assumption asserting that solving the 1-vs-2 cycles problem in the massively parallel communication model requires at least a logarithmic number of rounds of communication, even for a randomized algorithm that succeeds with high probability (having a ...
According to the BCM model, when a pre-synaptic neuron fires, the post-synaptic neurons will tend to undergo LTP if it is in a high-activity state (e.g., is firing at high frequency, and/or has high internal calcium concentrations), or LTD if it is in a lower-activity state (e.g., firing in low frequency, low internal calcium concentrations).

Learning theory describes how students receive, process, and retain knowledge during learning. Cognitive, emotional, and environmental influences, as well as prior experience, all play a part in how understanding, or a worldview, is acquired or changed and knowledge and skills retained. [1] [2]
In general, the risk () cannot be computed because the distribution (,) is unknown to the learning algorithm. However, given a sample of iid training data points, we can compute an estimate, called the empirical risk, by computing the average of the loss function over the training set; more formally, computing the expectation with respect to the empirical measure:
The start of a new year is a great time to re-evaluate your retirement status in terms of learning a new hobby. The first month of a new year is an opportunity to review your portfolio and ensure ...
Monday marks the fourth anniversary of the violent events of Jan. 6, 2021 -- a day President-elect Donald Trump has continually tried to recast as a "day of love." Trump is vowing to pardon Jan. 6 ...
Bayesian learning mechanisms are probabilistic causal models [1] used in computer science to research the fundamental underpinnings of machine learning, and in cognitive neuroscience, to model conceptual development. [2] [3] Bayesian learning mechanisms have also been used in economics [4] and cognitive psychology to study social learning in ...
Holiday preparations are in full swing, and no one wants to be on the “bad” list this time of year. When it comes to our legal climate, however, Louisiana has managed just that, even after ...
