Russian neural networks (neuromodels) and Artificial intelligence works by Cognitive Systems Company
MFC Service
BRAIN2MFC is a software for Promobot robots that are “working” at multifunctional government service centers. It allows the visitors to choose the needed service on request using natural language.
Key software features
A. Identification of queries, which do not correspond to the topic and providing relevant answers to correct questions. For example, on the question “Where do I get a passport of a pirate?” the system will answer “I don’t know”. On the other hand, a correct question “Where do I get a passport” will be answered with a relevant MFC service.
B. Paraphrase recognition. The system gives the correct answer to the various forms of a question – for example, "how to get a passport?", "how to get an identity card?", etc.
C. Assessment of the system's responses "confidence level" . If the system’s "confidence" is below the specified level, it can either reply "no answer", or provide the most relevant option, but notify that it is not sure about it.
The model shows 95.6% of correct classifications when tested with correct and incorrect queries.
Brain2 BLM — Big Linguistic Model
Big Linguistic Model is a kind of language processor capable of working with Russian and English texts.
The model is able to detect errors in words and sentences, determine the morphological properties of words and construct phrases according to linguistic norms. On the basis of BLM it is possible to create intelligent dialogue and reference systems trained on natural text without pre-processing and splitting it into question-answer pairs, which significantly simplifies the task.
At the moment the link below allows to test one of the BLM modules – words spelling checker — Brain2Spell.

Brain2Text
Cases based on Several multi-layer neuromodels (automated)
Brain2Text (DSSM). Example of an intelligent assistance system.
5 multi-layer Brain2Text models, trained according to the text fragment of the Sberbank strategy, consisting of 8200 words and 800 sentences, allows to perform a semantic search of query-relevant tokens for a response with an accuracy of 0.86 and synthesize from these lexemes a response in the form of a sentence with an accuracy of 0.91 (f-measure 0.9).

Cases based on multi-layer neuromodels (automated)
Brain2Chat: Virtual query service assistant.
A multi-layer Brain2Chat model, trained in 1000 question-answer pairs on the content of the fragment of the Sberbank strategy, allows to do a semantic search of query-relevant answers with an accuracy of 80%
(f-measure 0.90).
Brain2BusinessIntelligence
Cases based on one multi-layer neuromodel
House Prices Kaggle Task:
The House Prices model trained for 2 minutes 33 seconds on 79 parameters of 1461 objects of real estate predicts the cost of an object with an average error < 0.42 (classification time <1sec.)
Digit Recognition (MNIST) Kaggle Task:
The model for recognition of handwritten digits (Digit Recognizer) trained for 20 minutes on 784 parameters (28x28 pixels image) for 28 000 images allows to recognize handwritten numbers with an accuracy of 81% (classification time 1-2sec.).
Brain2Helpdesk (SSM). Intelligent search through the contents of files.
Three Brain2Helpdesk models were trained in 100 documents containing 1200 sentences. They allow instant semantic search of relevant documents with an accuracy of 88%.
The answer is also provided in a variative Telegram сhat-bot.
Research project
Based on Several multi-layer neuromodels
Pushkin Project
The aim of the project is to teach AI to compose poems in the style of the most prominent Russian poet (quatrains with iambic tetrameter). To do this, the company has developed models to determine and select rhymes and stresses in the word. Moreover, work is underway on a model of semantic associations over a group of words and text combinations.
