  2. Artificial intelligence content detection - Wikipedia

    en.wikipedia.org/wiki/Artificial_intelligence...

    Glossary. v. t. e. Artificial intelligence detection software aims to determine whether some content (text, image, video or audio) was generated using artificial intelligence (AI). However, the reliability of such software is a topic of debate, [1] and there are concerns about the potential misapplication of AI detection software by educators.

  3. Hallucination (artificial intelligence) - Wikipedia

    en.wikipedia.org/wiki/Hallucination_(artificial...

    In the field of artificial intelligence (AI), a hallucination or artificial hallucination (also called bullshitting, [ 1][ 2] confabulation[ 3] or delusion[ 4]) is a response generated by AI which contains false or misleading information presented as fact. [ 5][ 6][ 7] This term draws a loose analogy with human psychology, where hallucination ...

  4. Lie detection - Wikipedia

    en.wikipedia.org/wiki/Lie_detection

    Lie detection is an assessment of a verbal statement with the goal to reveal a possible intentional deceit. Lie detection may refer to a cognitive process of detecting deception by evaluating message content as well as non-verbal cues. [1] It also may refer to questioning techniques used along with technology that record physiological functions ...

  5. fMRI lie detection - Wikipedia

    en.wikipedia.org/wiki/FMRI_lie_detection

    fMRI lie detection is a field of lie detection using functional magnetic resonance imaging (fMRI). FMRI looks to the central nervous system to compare time and topography of activity in the brain for lie detection. While a polygraph detects anxiety-induced changes in activity in the peripheral nervous system, fMRI purportedly measures blood ...

  6. Precision and recall - Wikipedia

    en.wikipedia.org/wiki/Precision_and_recall

    Precision and recall. Precision and recall. In pattern recognition, information retrieval, object detection and classification (machine learning), precision and recall are performance metrics that apply to data retrieved from a collection, corpus or sample space . Precision (also called positive predictive value) is the fraction of relevant ...

  7. Viola–Jones object detection framework - Wikipedia

    en.wikipedia.org/wiki/Viola–Jones_object...

    The Viola–Jones object detection framework is a machine learning object detection framework proposed in 2001 by Paul Viola and Michael Jones. [1] [2] It was motivated primarily by the problem of face detection, although it can be adapted to the detection of other object classes. The algorithm is efficient for its time, able to detect faces in ...

  8. Brain fingerprinting - Wikipedia

    en.wikipedia.org/wiki/Brain_fingerprinting

    Brain fingerprinting ( BF) is a lie detection technique which uses brain waves from a electroencephalography (EEG) to determine whether specific information is stored in the subject's cognitive memory. It was invented by Larry Farwell, a Harvard -graduated neuroscientist, and published in 1995. [ 1] The technique involves presenting words ...

  9. Speech recognition - Wikipedia

    en.wikipedia.org/wiki/Speech_recognition

    Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also known as automatic speech recognition ( ASR ), computer speech recognition or speech-to-text ( STT ).
