  • Publication number: 20260073418
    Abstract: Systems and methods for providing real estate trends and other insights based on a natural language process of text data, including various news sources, to a specified market (e.g., national, local). In some embodiments, the real estate prediction system performs semantic-based analysis to determine a sentiment associated with a source. For example, the real estate prediction system can access an embedding system to generate embeddings for words and phrases contained within a source. These embeddings can be input to an LLM for determination of a general sentiment of the source, or used directly in an LLM. The real estate prediction system perform additional semantic analysis, such as word counting, to classify and organize the content of sources. Based on the generated sentiments, the real estate prediction system can generate predictions, estimations, and other insights relating to the sources.

  • Patent number: 11501100
    Abstract: A computer system and associated processes are disclosed for grouping similar real estate properties into contiguous neighborhoods, and for generating neighborhood-specific models capable of estimating property values within their respective neighborhoods. A clustering component uses various sources of property-level data to group properties based on measures of property similarity. For example, the clustering component may use features extracted from property images to identify properties with similar characteristics. As another example, the clustering component may measure property similarity based on how frequently specific properties are designated as comparable in appraisal reports. A model generator uses a machine learning process to determine, for specific neighborhoods, correlations between property attributes and values, and uses these correlations to generate the neighborhood specific models.

  • Patent number: 8666319
    Abstract: Techniques are provided to adaptively adjust a clear channel assessment threshold for use when a wireless device is to transmit in a wireless network that operates on a channel in a radio frequency band. A first wireless device, configured to wirelessly communicate with one or more second wireless device in the wireless network, receives energy on the channel in the frequency band, analyzes the received energy to detect interference on the channel and determines a type of interference detected in the received energy. The clear channel assessment threshold is adjusted by an amount depending on the type of interference detected.
