“true” cost gradient. Due to its stochastic nature, the path towards the global cost minimum is not “direct” as in Gradient Descent, but may go “zig-zag” if we are visuallizing the cost surface in a 2D space. However, it has been shown that Stochastic Gradient Descent almost ...
so people propose to give up the pursuit of the optimal solution, as long as the results given by the algorithm can be guaranteed to be within the "acceptable range". So there are "approximation algorithms"; if this is too difficult, then use metaphysical algorithms - ...
the key takeaway in this method is that we are feeding the raw pixels as the input to the machine learning algorithms and learning the parameters of the classifiers for image classification. after that, people started to realize that not all the information present in the image i...
they are not suitable for secure cryptographic implementations. For such uses, a cryptographically secure PRNG is required. A combination of algorithms can also help achieve a more secure approximation of a true random number.
If there are some unwanted linear dependencies in the frequencies, we can do some linear algebra to eliminate one of the frequencies (using some geometry of numbers to keep the quantitative bounds under control) and continue the iteration. If instead the approximation is too inaccurate, then the...
There are many seminorms of interest that one places on functions that are bounded by on -bounded functions, such as the Gowers uniformity seminorms for (which are genuine norms for ). All seminorms in this post will be implicitly assumed to obey this property. In additive combinatorics, ...
And if the machines are so smart, why are they still so dumb? The point of learning is to improve results. For the best results, a model needs to be both powerful and accurate. Machine learning is a field of study within artificial intelligence, concerned with making algorithms that can ...
In this blog, we provide a comprehensive understanding of vector databases, including what they are, how they work, types, use cases, examples, and more.

Reaction networks (RNs) comprise a set X of species and a set $$\mathscr {R}$$ of reactions $$Y\rightarrow Y'$$ , each converting a multiset of educts $$Y\subseteq X$$ into a multiset $$Y'\subseteq X$$ of products. RNs are equivalent to directed hypergra
