Publication number: 20240104394Abstract: Provided are computing systems, methods, and platforms that automatically produce production-ready machine learning models and deployment pipelines from minimal input information such as a raw training dataset. In particular, one example computing system can import a training dataset associated with a user. The computing system can execute an origination machine learning pipeline to perform a model architecture search that selects and trains a machine learning model for the training dataset. Execution of the origination machine learning pipeline can also result in generation of a deployment machine learning pipeline configured to enable deployment of the machine learning model (e.g., running the machine learning model to produce inferences and/or optionally other tasks such as re-training and/or re-tuning the model).Type: ApplicationFiled: March 11, 2022Publication date: March 28, 2024Inventors: Amy Skerry-Ryan, Quentin Lascombes de Laroussilhe, Ronald Rong Yang, Carla Marie Riggi, Chansoo Lee, Jordan Arthur Grimstad, Christopher Mark Lamb, Joseph Michael Moran, Nihesh Anderson Klutto Milleth, Noah Weston Hadfield-Menell, Volodymyr Shtenovych, Ziqi Huang, Sagi Perel, Michael David Gerard, Mehadi Seid Hassen

Patent number: 6197095Abstract: A subsea multiphase fluid separation system and method are disclosed which provide for efficient and reliable remote separation operation at deep and ultra deep water depths including depths of ten thousand feet or more. The system is preferably of modular construction wherein the modules are secured in a single frame to be lowered as a unit to the seabed. The system utilizes reliable cyclonic operation. The sequence of process steps is designed to make the system more efficient as compared to surface separating systems and thereby permit a more compact size as is desirable for subsea operation. The method of operation includes up to five basic process steps with the initial step in one embodiment including cyclonically separating solids. In a presently preferred embodiment, the cyclonic solids separator is sized to eliminate solids greater than fifty microns. A second stage is directed to cyclonically removing bulk gas from the liquid in either a cyclone or auger separator.Type: GrantFiled: February 16, 1999Date of Patent: March 6, 2001Inventors: John C. Ditria, David A. Hadfield

Patent number: 5498346Abstract: An oil spill recovery system includes a first hydrocyclone separator and optionally a second hydrocyclone separator located on a floating vessel floating on a body of water from which spilled oil is to be recovered. A recovered fluid containing oil and water emulsion and a large amount of free sea water is recovered from the body of water. The first hydrocyclone separator separates the recovered fluid into a first underflow stream containing oily water and a first overflow stream which contains substantially all of said oil and water emulsion. The oily water underflow stream from the first hydrocyclone separator is then directed to a second hydrocyclone separator which separates it into a second underflow stream which is returned to the sea as clean water, and a second overflow stream. The first overflow stream is stored in on-board ship's storage. The second overflow stream may be stored in ship's storage or recycled for further separation.Type: GrantFiled: September 6, 1994Date of Patent: March 12, 1996Assignee: Conoco Specialty Products, Inc.Inventors: David A. Hadfield, Mark F. Schubert

Patent number: 5302294Abstract: A hydrocyclone separator separates an oil and water stream into an underflow stream containing primarily water and an overflow stream containing a relatively higher oil concentration than the underflow stream. Quality control of both the underflow stream and the overflow stream is of concern, and typically a de-oiling separator is placed downstream on the underflow stream, and a dewatering separator is placed downstream on the overflow stream from the hydrocyclone separator. A degassing separator is also generally utilized upstream of the inlet to the hydrocyclone separator. Various monitoring and control systems are provided for controlling the split ratio of the underflow and overflow streams of the hydrocyclone separator.Type: GrantFiled: May 2, 1991Date of Patent: April 12, 1994Assignee: Conoco Specialty Products, Inc.Inventors: Mark F.
