### Spherical coordinate system - Wikipedia

https://en.wikipedia.org/wiki/Spherical_coordinate_system

In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuthal angle of its orthogonal projection on a reference plane that passes through the origin and is …

### Dot product - Wikipedia

https://en.wikipedia.org/wiki/Dot_product

The dot product is thus characterized geometrically by = ‖ ‖ = ‖ ‖. The dot product, defined in this manner, is homogeneous under scaling in each variable, meaning that for any scalar α, = = ().It also satisfies a distributive law, meaning that (+) = +.These properties may be summarized by saying that the dot product is a bilinear form.Moreover, this bilinear form is positive definite ...

Example: Firing threshold. In Fig. 2.8 B an action potential (solid line) has been initiated by a short current pulse of 1ms duration. If the amplitude of the stimulating current pulse is reduced below some critical value, the membrane potential (dashed line) returns to the rest value without a large spike-like excursion; cf. Fig. 2.8 B. Thus we have a threshold-type behavior.

### Sentiment Analysis using Logistic Regression and Naive Bayes

Nov 28, 2020  · We aim to reduce cost by improving the theta using the following equation: θj:=θj−α*∂J(θ)/θj. Here, α is called the learning rate. The above process of making hypothesis (h) using the sigmoid function and changing the weights (θ) using the derivative of cost function and a specific learning rate is called the Gradient Descent Algorithm.
