Publication number: 20250103300Abstract: The embodiments are directed to generating source code for a program from a problem description. One or more pre-trained code large language models (LLMs) generate sub-modules from a problem description in a natural language. The sub-modules are filtered based on testing criteria and encoded into sub-module encodings in an embedding space. The sub-module encodings are clustered into multiple clusters. A subset of sub-modules encoding that are close to the centroids of the clusters are selected. The sub-set of sub-modules is decoded into representative sub-modules. The problem description is augmented with the representative sub-modules and fed into one or more pre-trained code LLMs and new sub-modules are generated. The iterations continue until a program is generated from the representative sub-modules.Type: ApplicationFiled: January 26, 2024Publication date: March 27, 2025Inventors: Hung Le, Hailin Chen, Amrita Saha, Akash Gokul, Doyen Sahoo, Shafiq Rayhan Joty

Patent number: 12204857Abstract: Embodiments described herein provide training a prompt generator for text classification. A first training dataset associated with a first plurality of class labels is received for a first training process. For a first instance of the first training dataset, a set of labels of interest is generated by sampling from a set of possible class labels including the first plurality of class labels. The prompt generator generates a first prompt based on the set of labels of interest. A pretrained language model generates a task output in response to an input of the first instance prepended with the first prompt. A loss objective is generated based on the task output and the set of labels of interest. Parameters of the prompt generator are updated based on the computed loss function via backpropagation while the pretrained language model is frozen.Type: GrantFiled: November 28, 2022Date of Patent: January 21, 2025Assignee: Salesforce, Inc.Inventors: Hailin Chen, Amrita Saha, Shafiq Rayhan Joty, Chu Hong Hoi

Systems and methods for contextualized and quantized soft prompts for natural language understanding
Patent number: 12147765Abstract: Embodiments described herein provide a soft prompt tuning technique referred to as the Vector quantized Input-contextualized Prompt (VIP). The VIP techniques has two integral properties i) instead of learning a fixed set of prompt tokens irrespective of the input, it generates a contextualized version of the soft prompts, conditional on the input text ii) it further passes the input-contextualized prompt tokens through a quantization network, inspired by Vector Quantized Transformers. The quantization network uses nearest neighbor search over a learnable codebook to train a discrete latent variable model over the prompt-space, thus generating quantized version of contextual prompt tokens. These quantized contextual prompt tokens are finally fed into the frozen language model along with the original input text.Type: GrantFiled: August 16, 2022Date of Patent: November 19, 2024Assignee: Salesforce, Inc.Inventors: Rishabh Bhardwaj, Amrita Saha, Chu Hong Hoi -

Publication number: 20240249077Abstract: Embodiments described herein provide a data driven framework that (i) translates demonstration examples to a fixed-length soft prompt—a sequence of soft tokens; and (ii) learns a global (not generated from demonstrations) soft prompt. The framework then combines the global prompt, the translated prompts and the original context to create an augmented context which is given as final input for the backbone LM to use.Type: ApplicationFiled: May 12, 2023Publication date: July 25, 2024Inventors: Hailin Chen, Shafiq Rayhan Joty, Amrita Saha, Chu Hong Hoi

Publication number: 20240201958Abstract: Methods, systems, apparatuses, devices, and computer program products are described. A system may collect a first set of profiling data associated with computational resource consumption of one or more code implementations or methods. The system may use a vector embedding translation to convert the profiling data into one or more vector spaces. Each vector space may include a set of vectors, and each vector may correspond to an execution of a code implementation or method. The system may use the vector spaces to generate a model representation of the computational resource consumption of the one or more code implementations. In some cases, the system may collect and convert a second set of real-time profiling data into vector spaces, which the system may compare to the model representation such that users may identify deviations from resource consumption footprints.Type: ApplicationFiled: December 14, 2022Publication date: June 20, 2024Inventors: Ajay Krishna Borra, Manpreet Singh, Ravi Sankar Pulle, Amrita Saha
