  • Publication number: 20240296961
    Abstract: A system and method for modeling neuronal synaptic functionality at least partially instantiated on an optimized computation core of one or more high-speed processors. The synaptic model is preferably created as a neural net and includes, at least, a presynaptic component with a presynaptic target having, at least, a plasticity parameter and activity spike strength. The model also includes a retrograde signaling component with a retrograde messenger that selectively generates a molecular uptake signal, and a postsynaptic receptor component. The retrograde messenger acts on a presynaptic target to modulate the plasticity parameter and activity spike strength of the presynaptic component based upon a calculated molecular uptake at the postsynaptic receptor component to generate the molecular uptake signal which is then transmitted to the presynaptic component.

  • Publication number: 20240211815
    Abstract: Research work in the literature on imputation of mobility data for missing records of a subject's location trajectory has been specifically revolved around usage of historical data. Thus, performances drop when missing records or imputation mobility data for unknown subject with very little or no historical data has to be predicted. A method and system for training an ensemble classifier for imputation of mobility data of unknown subject based on cohort of the unknown subject is disclosed. The method and system disclosed herein exploits the knowledge that semantic trajectories of different individuals has considerable similarity when individuals belong to the same cohort. This concept is used by the method to predict the behavior of all the individuals in a cohort using ensemble classifier, also referred to as imputation model, trained on the semantic location data of a fraction of total individuals in the cohort with a certain accuracy.

  • Publication number: 20240120085
    Abstract: Existing systems for behavioural tracking and identification have the disadvantage that they do not analyse data in behavioural aspects. As a result, they lack ability to pre-empt scenarios involving actions that adversely affect user health. The disclosure herein generally relates to behavior prediction, and, more particularly, to a method and system for identifying unhealthy behavior trigger and providing nudges. The system generates a casual inference model, which is a reverse causality model facilitating mapping of context with one or more behaviour of the user. The system further collects and processes real-time data using the casual inference model, to perform behavioral analysis of the user.

  • Publication number: 20240045739
    Abstract: A system and method for routing requests to an API to two or more API endpoints are disclosed. The system comprises at least a gateway router and a configuration server. When software is executed, the system transmits, from the configuration server to the gateway router, information setting a desired proportion of API requests to be allocated to each of the two or more API endpoints. When API requests are received, the gateway router forwards the API requests to the API endpoints in the desired proportion. The system receives metrics data from one or more backend entities upon which at least one of the API endpoints relies for data or other services, and determines that an adverse event is underway or imminent based at least in part on the received metrics data. In response to the event, it forwards the API requests in a second proportion different from the desired proportion.

  • Patent number: 11521281
    Abstract: This disclosure relates generally to method and system for performing negotiation task using reinforcement learning agents. Performing negotiation on a task is a complex decision making process and to arrive at consensus on contents of a negotiation task is often expensive and time consuming due to the negotiation terms and the negotiation parties involved. The proposed technique trains reinforcement learning agents such as negotiating agent and an opposition agent. These agents are capable of performing the negotiation task on a plurality of clauses to agree on common terms between the agents involved. The system provides modelling of a selector agent on a plurality of behavioral models of a negotiating agent and the opposition agent to negotiate against each other and provides a reward signal based on the performance. This selector agent emulate human behavior provides scalability on selecting an optimal contract proposal during the performance of the negotiation task.

  • Publication number: 20220093249
    Abstract: In presence of high-cardinality treatment variables, number of counterfactual outcomes to be estimated is much larger than number of factual observations, rendering the problem to be ill-posed. Furthermore, lack of information regarding the confounders among large number of covariates pose challenges in handling confounding bias. Essential is to find lower-dimensional manifold where an equivalent problem of causal inference can be posed, and counterfactual outcomes can be computed.

  • Publication number: 20210326727
    Abstract: Causality is a crucial paradigm in several domains where observational data is available. Primary goal of Causal Inference (CI) is to uncover cause-effect relationship between entities. Conventional methods face challenges in providing an accurate CI framework due to cofounding and selection bias in multiple treatment scenario. The present disclosure computes a Propensity Score (PS) from a received CI data for the plurality of subjects under test for a treatment. A Generalized Propensity Score (GPS) is computed for a plurality of treatments corresponding to the plurality of subjects by using the PS. Further, a plurality of task batches are created using the GPS and given as input to the DNN for training. Errors in factual data and in balancing representation of the DNN are rectified using a novel loss function. The trained DNN is further used for predicting the counter factual treatment response corresponding to the factual treatment data.

  • Patent number: 8524189
    Abstract: The present invention provides a process for the selective oxidation of hydrogen sulphide contained in a hydrogen sulphide-containing hydrocarbon feed gas to elemental sulphur. The hydrogen sulphide-containing hydrocarbon feed gas and a sulphur dioxide-containing gas are supplied to a reaction zone containing a TiO2-comprising catalyst, wherein elemental sulphur and a gaseous stream depleted in hydrogen sulphide are formed. The gas feeds are contacted with the TiO2 containing catalyst at elevated pressure and at a temperature in the range of from 120 and below 160 ° C., under such conditions that the elemental sulphur formed is essentially in liquid form. At least part of the sulphur dioxide-containing gas is obtained by combusting elemental sulphur to obtain a gaseous mixture of sulphur dioxide and nitrogen and then concentrating the gaseous mixture to provide the sulphur dioxide-containing gas.
