Abstract

Systems and methods for automatically finding and fixing faults in software programs. The methodology is implemented by a tool that works solely on the basis of program text, using a prover. The tool verifies program code with a prover and if a fault is found, a set of counterexamples are generated that illustrate the causes of the proof failure. The tool uses the counterexample to infer invariants that characterize the circumstances under which the failure occurs. These invariants are used to generate candidate fixes, which are then validated by the prover. Correct fixes are applied to the program.

Abstract

A system determines whether a first operation performed by an MLM is compatible with a specific encryption scheme, wherein the MLM is distributed over at least one client device and at least one server. In response to determining that the first operation is compatible with the specific encryption scheme, the system encrypts data associated with the first operation using the specific encryption scheme, and transmits the encrypted data to the at least one server configured to apply the first operation.

Abstract

A system parses an input training dataset by classifying public data and private data in the input training dataset. The system tokenizes the public data into standard tokens and the private data into secret tokens. The system trains an MLM using the standard tokens and the secret tokens to generate, for a given input prompt, a output response that does not reveal any values in the private data. The system receives a user prompt, and executes the trained MLM on the user prompt to generate a masked output response comprising at least one secret token. The system de-tokenizes, the at least one secret token, in the masked output response based on the tokens and user credentials of the user. The system outputs a version of the masked output response with the at least one secret token replaced with a corresponding value of the private data based on the user credentials.

Abstract

A system receives a training dataset for the LLM that includes confidential data, wherein the LLM comprises preset parameters. The system trains the LLM using the training dataset, including: identifying one or more parameters changed during the training, and encrypting the changed parameters. The system receives an input query for the LLM from a user. The system determines if the user has access rights to the confidential data. In response to determining that the user has the access rights to the confidential data, the system decrypts the encrypted changed parameters of the LLM, and performs an LLM inference using the decrypted changed parameters. In response to determining that the user does not have the access rights to the confidential data, the system performs the LLM inference with the preset parameters without decrypting the encrypted changed parameters.

Abstract

Systems and methods for generating video highlights with a certain label and a specific duration (SD) using a trained ranking neural network (RankNet). The system obtains a request for highlight generation, specific duration, and a specific label. The video is split into a set of fragments of pre-defined duration forming a sequence. Digital representation in a form of 3D spatio-temporal embedding is generated for each fragment by a spatio-temporal encoder. Using the embedding value, a rank of each fragment is identified by a trained Ranking Neural Network. Ranks are recorded into a data structure. A minimum number of fragments are selected to cover the SD using a criteria comprising comparing ranks of different fragments. A video highlight is generated from concatenated selected fragments with a truncation, if necessary.

Abstract

Systems and methods for automatic generation of highlights of video. The system includes a video processor to select one type of the video to be analyzed and split video clips from the video. The video processor recognizes positive clips, negative clips, and auxiliary clips. A spatio-temporal encoder is configured to select, from the recognized clips, a main positive clip, a main negative clip, and auxiliary positive and negative clips, and generate a three-dimensional (3D) embedding vector of each clip. The selected clips are processed by a ranking network having a self-attention layer. The self-attention layer, using a query head, a key head and the value head produces self-attention resultant vector on which an activation function is performed. A rank value is thus obtained for the selected clip. Based on the rank value, video highlights are generated.
