Design and analysis of dynamic systems
The representation of physical and information processes occurring in technical systems in the form of a sequence of interconnected blocks can be considered one of the most convenient in practical terms.
Such network systems are one of the most commonly used representations of control systems, analog and digital signal processing, economic supply and consumption systems, etc.
Representation of the system under study in the form of blocks connected by directed or non-directed connections makes it possible to present in a convenient form the system of equations describing it and, in addition, to additionally take into account structural relationships, which provides additional information necessary for an effective solution.
Network models of dynamical systems make it possible to describe the change in time of a certain set of scalar quantities tied to the relationships between elemental ones.User Manual - ECA

Calculation of Electrical Circuits in APM Products
ECA provides tools for generating and calculating network models of dynamic systems. The calculation of the dynamics of the system is carried out using implicit and semi-implicit schemes of various orders. Built-in subsystem generation tools allow you to create composite models that include other dynamic and electrical systems as individual elements. The program includes tools for expanding functionality by including additional elements, the functional description of which is carried out by means of the Python or Julia programming languages.
The capabilities of the program make it possible to simulate a wide range of processes and phenomena, since any system of integro-differential-algebraic equations can be correlated with a network model of a dynamical system. Such models are a natural description of control and filtration processes, oscillatory processes in mechanical systems, and information processes in communication systems.

- Machine learning
One of the most important trends in the modern design of technical systems is the inclusion of adaptive elements in the design, the law of functioning of which is determined not only (and sometimes not even so much) by the design parameters determined at the design stage, but is determined in the process of functioning of the system in a real or simulated environment based on the condition of achieving certain technical and economic indicators. Such elements include various kinds of statistical classifiers, identification systems (including neural networks), pattern recognition, etc.
The inclusion of adaptive elements in a dynamic or stationary system under development usually consists of the following steps:
- determination of the structure of the adaptive system. At present, network systems (in particular, neural networks) that sequentially, layer by layer, transform a multidimensional input value into a single- or multidimensional output value are most practically used;
- selection of the "quality criterion" of the system's functioning. At this critical stage, a criterion is established on the basis of which the values of free system parameters will be selected. Depending on the purposes of further use, such a criterion may be the standard deviation of the observed response of the adaptive system from the known target (as, for example, in the adaptive filtering problem), the average value of a certain generated value, etc.;
- training. At this stage, the system is simulated and its free parameters are determined based on the condition for achieving the established quality criterion. This procedure is computationally time-consuming and requires the use of specialized algorithms for an effective solution;
- evaluation of results. After the training procedure, a repeated simulation of the system's behavior is carried out in conditions closer to reality. Depending on the results obtained at this stage, a decision is made on the need for repeated training, or a change in the structure of the adaptive system;
- Inclusion of the trained system as a component of the main (real or simulated) system.

The network model can have an arbitrary depth (the depth of the network model is understood as the maximum distance from the receiver to the element of the "teacher" type). The learning algorithm is selected on the basis of the analysis of the structure of the model, the differentiability of the elements included in its structure and the established criteria for assessing the quality of the system's functioning. The user can set an element-by-element or batch training strategy, batch size, and regularization parameters.
ECA capabilities can be used to develop adaptive, including neural network control systems, continuous and discrete filters, as well as to solve the problems of identifying dynamic systems with their subsequent use as components in other models, pattern recognition, state diagnostics systems, etc. is described by means of the Python or Julia programming languages.

Parametric Optimization
In the design of dynamic systems, the problem of choosing the values of design parameters at which the best functional indicators will be achieved is quite common. Traditionally, this problem is solved by sequential modeling of the system's behavior at different values of design parameters with the subsequent selection of the best of the alternatives used. Modern computing tools make it possible to automate this procedure through the use of numerical optimization methods, leaving the designer only with the responsibility to specify the criterion for assessing the quality of the system for a certain set of values of design parameters, as well as restrictions on the possible values of these parameters. Such restrictions are most often nomenclature restrictions, that is, the possibility of choice is limited to a certain set of possible combinations of parameter values known in advance, or interval restrictions, that is, the indication of a permissible range of values for each of the parameters.
It's easy to see that the parametric optimization problem has a lot in common with the machine learning problem. Indeed, if we imagine the model of a dynamic system as a kind of "black box", the input of which is a vector of values of the parameters to be optimized, and the output is the parameters of the functioning of this system to be evaluated, then such a "box" can be considered as an element of an adaptive network system. It is important to note that in this case it is quite permissible to use not only some numerical (e.g., integral) characteristics as criteria for assessing the quality of the functioning of a dynamic system, but to make a decision proceeding, for example, from the width of the spectrum of the observed output signal. In other words, such an approach makes it possible to formulate rather complex composite criteria for assessing the quality of the system's functioning.

Parametric Optimization and Machine Learning in the APM Environment
With the use of ECA, developed by the R&D Center "APM", it is possible to perform all stages of the design of dynamic systems with trainable elements. The capabilities of the program allow you to design and train various types of neural networks, linear and nonlinear regression models and classifiers, solve clustering and data dimensionality reduction problems. An important distinguishing feature of the software product is the ability to combine models of dynamic systems and models of adaptive network systems. This allows, for example, to use the values of the dynamic characteristics of the designed system as criteria for the quality of functioning - transient time, average power generated, friction losses, etc., as well as to effectively formulate and solve the problem of parametric optimization for various subsets of the system's design parameters.
The network adaptive model is represented in the form of connected blocks (elements), each of which converts the input tensor (vector, matrix, or multidimensional array in general) value into the output value. Model elements are divided into the following categories:
- Sources are elements that do not have inputs and give values based on the established parameters.
- Sinks are elements that do not have outputs and perform actions that do not affect the functioning of the system (for example, displaying a value on a graph or in a file).
- Transforming elements that do not have free parameters and perform a given transformation of the input value into the output value (concatenation of values, calculation of distance, summation, etc.). The transformation can be both deterministic and stochastic.
- Teachable elements. They have free parameters that are adjusted during the training process to achieve the established quality criterion.
- Adaptive elements. They have an internal state that changes in accordance with their own quality criterion.
- "Teachers" are elements that assess the "quality" of the system
