What is the need of activation?
Definition of activation function:- Activation function decides, whether a neuron should be activated or not by calculating weighted sum and further adding bias with it. The purpose of the activation function is to introduce non-linearity into the output of a neuron.
Why is Gelu used?
The Gaussian Error Linear Unit, or GELU, is an activation function. The GELU activation function is x Φ ( x ) , where the standard Gaussian cumulative distribution function. The GELU nonlinearity weights inputs by their percentile, rather than gates inputs by their sign as in ReLUs ( x 1 x > 0 ).
What is the purpose of a power transformer?
Usually, electrical utilities use high voltage in long-distance transmission wires. However, this high voltage is too dangerous for home use. In the case of electrical utilities in homes, they use transformers to change the voltage of electricity as it travels from the power plant to your home.
Are there interfaces for explaining transformer language models?
Interfaces for Explaining Transformer Language Models – Jay Alammar – Visualizing machine learning one concept at a time. Interfaces for exploring transformer language models by looking at input saliency and neuron activation. . .
How is self attention used in a transformer?
Transformers make use of multi-headed self attention to perform encoding and decoding within the model to perform tasks such as language modelling (next-word prediction) and machine translation. Self-attention is a mechanism used to build representations based on the the pair-wise correlations between the elements in a sequence.
What is the purpose of a step up transformer?
First using a transformer, the voltage of electricity coming from a power plant is “stepped up” to the right level for long-distance transmission. Because high-voltage current can arc, step up transformers called ignition coils are used to power spark plugs.
