Reasoning AI
Augmented Fuzzy Symbolic AI
Xtractis is a Generalized “Fuzzy Symbolic AI” as it implements innovative mathematics based on the Theory of Fuzzy Relations of order N [Zalila 1993]. It is the result of over 250 scientist-years of high-level R&D in fuzzy mathematics and automatic induction.
This non-standard mathematics enables reasoning with continuous logics, which are more suitable than classic binary logic for modeling complex real-world problems, i.e., problems mixing imprecision, subjectivity, and epistemic uncertainty.
Knowledge-Generating AI
Xtractis is an “Augmented Fuzzy Symbolic AI” because it automatically discovers implicit knowledge in data and structures it into decision systems based on fuzzy rules.
It exhibits all the knowledge synthesized from the information included in the learning dataset. It allows domain experts to understand their processes and enrich their knowledge.
Collective & Evolving AI
Xtractis robots infinitely perfect their induction (resp. abduction) strategies to discover increasingly efficient models (resp. increasingly satisfactory solutions) without human supervision, first in competition, then in cooperation.
Frugal AI
Xtractis uses evenly small or big data. It manages low-quality or low-quantity data without imputation, i.e., without introducing bias in data before processing.
When the volume of data is limited, it induces models with higher predictive capacity than the best open-source AI techniques. The predictive capacity is also higher when comparing the models from different techniques at iso-complexity (similar model structure).
Human-Centric AI
Replicating Human Reasoning
Xtractis instantiates the three human reasoning modes in three software robots:
XTRACTIS GENERATE uses fuzzy induction to discover intelligible cause and effect models, as human scientists, thanks to the Experimental Scientific Method.
XTRACTIS PREDICT uses fuzzy deduction for its predictive analysis, calculating the predictions from the induced models rationally and deterministically.
XTRACTIS OPTIMIZE uses fuzzy abduction for its prescriptive analysis, discovering the most optimal solutions to validate a non-linear multi-objective request from induced or analytical models.
Enabling Audit & Certification of AI Decision Systems
Users and experts can validate their models before pushing to end-use, or audit them before submission to certification to comply with AI regulations for high-risk applications.
Enhancing Knowledge
& Augmenting Experts
Xtractis-induced models are fully auditable by the domain expert who confirms the correctness of the decisions of the AI system to be deployed. It rationally explains each decision made. The deductive reasoning followed to calculate each prediction is automatically drawn in a detailed report.
Highlighting Biases
& Deploying Ethical Transparent AI Systems
Xtractis induces rules that confirm the presence of noise deliberately introduced into the reference data or explain any conscious or unconscious bias that a decision-making process may contain. It also refuses to deliver a prediction if it is highly uncertain of its decision (for offline systems).
Trustworthy AI
Robust Models
Xtractis discovers highly accurate knowledge from data: induced top-models have sustained high predictive capacity, at least equal to that of the best open-source AI techniques. The platform includes an intensive model validation process to ensure their level of reliability in the end-use and an intensive benchmark versus the best challenging techniques. It also detects any noise in data, by highlighting the measured values that are strongly different from the predicted ones.
Intelligible & Explainable Models
Xtractis-induced models are natively transparent: they are systems of fuzzy "IF…THEN" unchained rules which only use native predictor variables (no synthetic ones). Their internal decision-making logic is obvious and each of their decision is easily explained and traced.
Stable Models
Xtractis-induced models have native formal stability: firstly, no prediction will come out of an interval determined in advance from the structure of the rules; second, any slight variation of a predictive variable will lead to a gradual variation of the fuzzy prediction. Still, strong non-linearities inherent to the complex process or pheomena under study are recognized and addressed when necessary.
Holistic Modeling
Xtractis considers in first intention all the available variables and their interactions to retain weak signals. Then, it automatically discards non-impacting variables. The complexity of the complex process or pheomena under study is naturally discovered ex-post. As models are multifactorial, their predicted decisions for each new case are highly personalized.
Powerful AI
General Purpose Behavioral AI
Xtractis is perfectly suited to non-linear modeling, whether it concerns human decisions or the behavior of artificial or natural processes: industrial or socio-economic phenomena, conscious or unconscious human decisions, sensory perception… You can quickly develop high-risk predictive applications regardless of your activity sector (Finance, Banking, Insurance, Health, Pharma, Biotech, Sciences, Smart Industry, Defense, Security, Cyber, Legal, Autonomous Machines, ADAS…), and your department (Management, Marketing, R&D, Domain Expertise...).

FAQ about Fuzzy AI Concepts
Fuzzy theory proposes formally rigorous concepts, techniques, and methods to model and deal with multidimensional knowledge and fuzzy data, i.e., real-world data that include imprecision, uncertainty, and/or subjectivity.
Fuzzy knowledge is information-rich: transforming it into binary knowledge at the beginning of the data processing induces a bias that inevitably affects the quality of the decision. Maintaining the fuzziness throughout the data processing and deciding only at the end of the process (final transition from a fuzzy decision to a binary decision) is much more adequate for accurate decisions.
In Fuzzy Theory, dual measures of Possibility and Necessity replace the measure of Probability when the decision maker must assess the occurrence of an event on which they have little historical data or poor quality data. This appears particularly in multi-criteria decision-making when information comes from human sensors (judgment, expert opinion).
The theory of possibility is thus adapted to account for the epistemic uncertainty linked to the lack of information. In particular, it allows the estimation of the occurrence of imprecise events, when the theory of probability is rather linked to the stochastic uncertainty characterizing the presence of “blind chance.”
Fuzzy logic and fuzzy set theory are used for the gradual and nuanced modeling of expert knowledge by replicating their mode of reasoning while allowing the definition of categories with ill-defined limits. By integrating both imprecision and uncertainty, it makes it possible to design decision-support systems that are more effective than conventional expert systems: an expert will be all the more confident of their assertions if they are authorized to be imprecise and will be all the more uncertain if they are forced to be precise. It also offers a high-performance alternative approach for modeling complex processes and non-linear phenomena. Fuzzy logic is part of the approach of Symbolic / Cognitive Fuzzy AI.
Fuzzy arithmetic allows the modeling and processing of approximate numerical quantities. It enables the design of more accurate predictive analytical models that are more faithful to reality.
The Fuzzy Relation of order N (FR-N) generalizes the concepts of scalar of [0,1] (FR-0), fuzzy set (FR-1), of fuzzy two-dimensional relation (FR-2) and extends them to an N-dimensional space. An FR-N thus defines a non-linear multi-dimensional equation.
FR-N theory introduces infinite logical operators of conjunction, disjunction, negation, inference, and anchor-composition. It shows how to create an infinity of fuzzy measures of possibility and necessity using the FR-N fusion composition operators.
This theory defines new original algebraic structures while exhibiting the corresponding maximum algebraic structures according to the operators used. Compared to other AI techniques, it thus allows a larger margin in non-linear non-convex non-connected non-monotonous, and non-decomposable modeling of complex processes and phenomena.
An “IF…THEN” fuzzy rule is a non-linear equation relating the causes to the effect, or a local non-linear model linking nuanced variables. Mathematically, it is defined by an FR-N, i.e. a non-linear multidimensional function connecting N-1 input variables to the output variable.
A fuzzy model or system is a collection of fuzzy rules covering the decision space. Any occurrence in this space leads to the simultaneous and gradual triggering of specific rules, then the interpolation of their decisions: local rules interact and cooperate to calculate the most appropriate final decision.
The more the model is composed of fuzzy rules and the more it uses input variables, the more it will succeed in accurately describing the behavior of a complex process. The feat of Xtractis is to find the actual level of complexity of the process under study: to discover the most robust and compact model.
Induction is the reasoning mode that makes it possible to discover general laws (i.e., a model) from observing given facts about causes and their consequences.
Deduction is the reasoning mode that finds the consequence of given causes from general laws.
Abduction is the reasoning mode that searches for particular possible causes for a given consequence from general laws.
