Geek girl at the Geek Picnic wearing a Geek shirt and a VR headset. The word geek is a slang term originally used to describe eccentric or non-mainstream people; in current use, the word typically connotes an expert or enthusiast obsessed with a hobby or intellectual pursuit.
Federated learning (also known as collaborative learning) is a sub-field of machine learning focusing on settings in which multiple entities (often referred to as clients) collaboratively train a model while ensuring that their data remains decentralized. [1] This stands in contrast to machine learning settings in which data is centrally stored.
In deep learning-based language models like GPT-4 or BERT, the context model is an inherent part of the architecture. These models use mechanisms such as attention mechanisms and multi-layered transformer (machine learning) architectures to capture contextual information from the input sequence. The context model takes into account the ...
Ant behavior was the inspiration for the metaheuristic optimization technique When a colony of ants is confronted with the choice of reaching their food via two different routes of which one is much shorter than the other, their choice is entirely random.
Learning inside a single layer ADALINE Photo of an ADALINE machine, with hand-adjustable weights implemented by rheostats. Schematic of a single ADALINE unit, from Figure 2 of (Widrow, 1960). ADALINE ( Adaptive Linear Neuron or later Adaptive Linear Element ) is an early single-layer artificial neural network and the name of the physical device ...
A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies.The DCT, first proposed by Nasir Ahmed in 1972, is a widely used transformation technique in signal processing and data compression.
Undersampling with ensemble learning. A recent study shows that the combination of Undersampling with ensemble learning can achieve better results, see IFME: information filtering by multiple examples with under-sampling in a digital library environment. [9]
An oracle machine or o-machine is a Turing a-machine that pauses its computation at state "o" while, to complete its calculation, it "awaits the decision" of "the oracle"—an entity unspecified by Turing "apart from saying that it cannot be a machine" (Turing (1939), The Undecidable, p. 166–168).
