Abstract: Aspects of the present disclosure provide techniques for image-based document search. Embodiments include receiving an image of a document and providing the image of the document as input to a machine learning model, where the machine learning model generates separate embeddings of a plurality of patches of the image of the document and the machine learning model generates an embedding of the image of the document based on the separate embeddings of the plurality of patches. Embodiments include determining a compact embedding of the image of the document based on applying a dimensionality reduction technique to the embedding of the image of the document generated by the machine learning model. Embodiments include performing a search for relevant documents based on the compact embedding of the image of the document. Embodiments include performing one or more actions based on one or more relevant documents identified through the search.

Abstract: In one aspect, the present disclosure relates to a method of generating business descriptions performed by a server, said method may include: receiving a plurality of invoices, each invoice being associated with a business of a plurality of businesses; extracting a plurality of texts from the plurality of invoices; embedding the plurality of texts to a vector space to obtain a plurality of invoice vectors; generating a plurality of clusters in the vector space, each cluster of the plurality of clusters comprising at least one invoice vector of the plurality of invoice vectors; generating a description for a cluster, the description for the cluster representing all invoice vectors assigned to the cluster; for each business of the plurality of businesses that has at least one invoice vector assigned to the cluster, associating the business with the description; and indexing the plurality of businesses within a database by the generated descriptions.

Abstract: Techniques for monitoring for fraudulent login attempts to remote services through an application. The method generally includes receiving a request to connect an application to a remote service. A login attempt counter tracking a number of attempts by a user to connect the application to one or more remote services is incremented. Based on determining that the login attempt counter is less than a maximum number of login attempts predicted to correspond to legitimate login activity in the application, the first username is compared to a second username included in a previous request. A distance is calculated between the first username and the second username, and one or more actions are taken to process the request based on determining whether the calculated distance exceeds a maximum predicted distance between usernames in successive requests that corresponds to legitimate login activity.

Abstract: Methods and systems classify and cluster invoice data. An invoice is obtained. A category vector is generated from an invoice string of the invoice with a dense layer of a machine learning model that includes an embedding layer, a neural network layer, and the dense layer. A suggestion is selected with a selection engine and in response to comparing the category vector to a set of clusters. The suggestion is presented.

Abstract: A method for recommending offerings to a business may include: receiving a request for recommended business offerings from a device; receiving business data associated with a business from the device, the business data comprising invoice data associated with the business; embedding the business data to a vector space to obtain a business vector, the vector space comprising a plurality of other vectors associated with other businesses; calculating a relation metric between the business vector and a vector of the plurality of other vectors, the vector being associated with a second business, the relation metric representing a degree of relation between the business and the second business; determining that the relation metric is above a pre-defined threshold value; and responsive to the determining, sending business data associated with the second business to the device, the business data associated with the second business comprising invoice data associated with the second business.

Abstract: Aspects of the present disclosure provide techniques for detecting latent bias in machine learning models. Embodiments include receiving a data set comprising features of a plurality of individuals. Embodiments include receiving identifying information for each individual of the plurality of individuals. Embodiments include predicting, for each respective individual of the plurality of individuals, a probability that the respective individual belongs to a given class based on the identifying information for the given individual. Embodiments include providing, as inputs to a machine learning model, the features of the plurality of individuals from the data set. Embodiments include receiving outputs from the machine learning model in response to the inputs. Embodiments include determining whether the machine learning model is biased against the given class based on the outputs and the probability that each respective individual of the plurality of individuals belongs to the given class.

Abstract: Certain aspects of the present disclosure provide techniques for monitoring for fraudulent login attempts to remote services through an application. The method generally includes receiving a request to connect an application to a remote service. A login attempt counter tracking a number of attempts by a user to connect the application to one or more remote services is incremented. Based on determining that the login attempt counter is less than a maximum number of login attempts predicted to correspond to legitimate login activity in the application, the first username is compared to a second username included in a previous request. A distance is calculated between the first username and the second username, and one or more actions are taken to process the request based on determining whether the calculated distance exceeds a maximum predicted distance between usernames in successive requests that corresponds to legitimate login activity.

Abstract: A method for increasing computer network security. A first request to attach a first user account for a software program to an external secure account is received. The first request includes a first set of user credentials for accessing the external secure account and a first unverified email address, the external secure account controlled by a second external computer. After receiving the first request, features having metrics is received. The metrics describe at least creation of the first user account and include at least the first unverified email address. A machine learning model processing the features calculates a probability score that the first request is fraudulent. The probability score is compared to a threshold to form a comparison result. A security action is performed with respect to attaching the first user account to the external secure account in response to the comparison result.

Abstract: A method for detecting an unauthorized activity on a computer system involves obtaining current time stamps for a first type of access event related to the computer system, determining a current count of the first type of access event using the current time stamps, and predicting an expected count of the first type of access event using a current count of time stamps and a predictive model. The method further involves obtaining an actual count of the first type of access event, executing a first comparison of the actual count with the expected count, determining, based on a test comprising the first comparison, that the unauthorized access to the computer system occurred, and issuing an alert indicating the unauthorized activity occurred.
