We note that the unknown constant 𝑚 in the force ⃑𝐹 cancelled out when we computed the cross product. Hence, the moment of ⃑𝐹 about point 𝐵 is 25⃑𝑘. In the previous example, we computed the vector moment of a planar force about a point using the formula 𝑀=...

I must note that in mathematics the "cross product" is technically only defined for 3D vectors. In 3D it’s a vector perpendicular to vectors a and b, and its formula is: a× b = (a.y*b.z - a.z*b.y, a.z*b.x - a.x*b.z, a.x*b.y - a.y*b.x)....
Vector multiplication (cross and dot product) can be very useful in physics but it also has its limitations and Geometric Algebra defines a new, more general, type of multiplication. This new type of multiplication generates new 'dimensions' so Geometric Algebra takes a vector algebra of dimension...

Some common algorithms for these tasks are linear regression, k-nearest neighbors, decision trees, random forest, gradient boosting, support vector machines, and neural networks. A description of these algorithms can be found in ref.60. XGboost (an implementation of gradient boosting)61 is often ...
1Altmetric Explore all metrics Abstract The deployment of deep learning models on resource-constrained devices requires the development of new optimisation techniques to effectively exploit the computational and storage capacities of these devices. Thus, the primary objective of this research is to introduc...
The dot product can be geometrically interpreted as a⋅b=|a||b|cosθ where |a| is the length of vector a, |b| is the length of vector b, and θ is the smaller angle between vector a and vector b. Using this formula, we can solve for the cosine of α. (e−j)⋅(t...
