Regional organizationRegional organizations (ROs) are, in a sense, international organizations (IOs), as they incorporate international membership and encompass geopolitical entities that operationally transcend a single nation state. However, their membership is characterized by boundaries and demarcations characteristic to a defined and unique geography, such as continents, or geopolitics, such as economic blocs. They have been established to foster cooperation and political and economic integration or dialogue among states or entities within a restrictive geographical or geopolitical boundary.
Hopfield networkA Hopfield network (or Amari-Hopfield network, Ising model of a neural network or Ising–Lenz–Little model) is a form of recurrent artificial neural network and a type of spin glass system popularised by John Hopfield in 1982 as described by Shun'ichi Amari in 1972 and by Little in 1974 based on Ernst Ising's work with Wilhelm Lenz on the Ising model. Hopfield networks serve as content-addressable ("associative") memory systems with binary threshold nodes, or with continuous variables.
Union of South AfricaThe Union of South Africa (Unie van Zuid-Afrika; Unie van Suid-Afrika; ) was the historical predecessor to the present-day Republic of South Africa. It came into existence on 31 May 1910 with the unification of the Cape, Natal, Transvaal, and Orange River colonies. It included the territories that were formerly a part of the South African Republic and the Orange Free State. Following World War I, the Union of South Africa was a signatory of the Treaty of Versailles and became one of the founding members of the League of Nations.
Colony of NatalThe Colony of Natal was a British colony in south-eastern Africa. It was proclaimed a British colony on 4 May 1843 after the British government had annexed the Boer Republic of Natalia, and on 31 May 1910 combined with three other colonies to form the Union of South Africa, as one of its provinces. It is now the KwaZulu-Natal province of South Africa. It was originally only about half the size of the present province, with the north-eastern boundaries being formed by the Tugela and Buffalo rivers beyond which lay the independent Kingdom of Zululand (kwaZulu in the Zulu language).
