What is a deterministic learning machine (DLM)?

A DLM is a processor that accepts input messages (input event after input event) and tries to discover relations between events through a primitive form of learning. A DLM does not store information about individual events. The DLM learns about the incoming messages by updating its internal representation of the learned knowledge. The DLM has several candidate update rules and selects the rule that minimizes a cost function. The selection process itself determines the type of response the DLM will send through one of its output channels. All steps of the algorithm that the DLM uses to perform its function are strictly deterministic.

By connecting an output channel to an input channel of another DLM networks of DLMs can be built. As the input of a network receives an event, the corresponding message is routed through the network while it is being processed and eventually a message appears at one of the outputs. At any given time during the processing, there is only one input-output connection in the network that is actually carrying a message. The DLMs process the messages in a sequential manner and communicate with each other by message passing only.

The update rules and selection process that define the DLM are not unique. In fact, we use three different variants. Independent of which type of DLM is used, the DLM network can generate data such that the averages agree with those of quantum theory.

What can DLMs do what other algorithms cannot do?

DLM networks can exhibit behavior that is normally considered as being of  quantum mechanical origin. The examples and publications on this website demonstrate that DLMs can be used to simulate quantum interference and universal quantum computation on an event-by-event basis. The same methodology has been used to simulate real Einstein-Podolsky-Rosen-Bohm experiments with photons, Wheeler's delayed choice experiments, quantum cryptography protocols etc.
