Current chatbots also have a hard time understanding misspellings, slang, and context-specific language, e.g., like the language used by students. “Learning” new topics is very time-consuming for current chatbots. And it is difficult for administrators to participate in student conversations carried out in part by current chatbots. To address these technical problems, an inventive chatbot uses a natural language processor (e.g., a neural network) to receive, classify, and respond to queries on thousands of different topics. An inventive chatbot can also request real-time assistance from an administrator when faced with a difficult query and learn on-the-fly from the administrator's response. This ability to learn on-the-fly gives inventive chatbots significant performance advantages over current chatbots. |

Auto load balancing
Automatic load-balancing techniques in a network device are used to select, from a multipath group, a path to assign to a flow based on observed state attributes such as path state(s), device state(s), port state(s), or queue state(s) of the paths. A mapping of the path previously assigned to a flow or group of flows (e.g., on account of having then been optimal in view of the observed state attributes) is maintained, for example, in a table. So long as the flow(s) are active and the path is still valid, the mapped path is selected for subsequent data units belonging to the flow(s), which may, among other effects, avoid or reduce packet re-ordering. However, if the flow(s) go idle, or if the mapped path fails, a new optimal path may be assigned to the flow(s) from the multipath group. |

Generic of doubly selective channel emulator, locally non-stationary in time, nonstationary in frequency, with non-separable dispersion function
Currently, wideband channel simulation/emulation is carried out through channel realizations obtained from dispersion functions dictated by communication standards, in order to perform the tests and validation of the new data communication schemes. However, the channel models available in the state of the art only consider the simulation/emulation of stationary channels with separable dispersion characteristics, allowing only the treatment of unrealistic channels.

To solve this, the orthogonalization technique of the channel is used in conjunction with a windowing scheme in order to generate arbitrarily long realizations of doubly dispersive channels. |

Automatic conversion of speech into song, rap or other audible expression having target meter or rhythm
Captured vocals may be automatically transformed using advanced digital signal processing techniques that provide captivating applications, and even purpose-built devices, in which mere novice user-musicians may generate, audibly render and share musical performances. In some cases, the automated transformations allow spoken vocals to be segmented, arranged, temporally aligned with a target rhythm, meter or accompanying backing tracks and pitch corrected in accord with a score or note sequence. Speech-to-song music applications are one such example. In some cases, spoken vocals may be transformed in accord with musical genres such as rap using automated segmentation and temporal alignment techniques, often without pitch correction. Such applications, which may employ different signal processing and different automated transformations, may nonetheless be understood as speech-to-rap variations on the theme. |

Encoding and decoding of interchannel phase differences between audio signals
A device for processing audio signals includes an interchannel phase difference (IPD) mode selector and an IPD estimator. The IPD mode selector is configured to select an IPD mode from among at least a first IPD mode and a second IPD mode based on at least an interchannel temporal mismatch value indicative of a temporal misalignment between a first audio signal and a second audio signal. The IPD estimator is configured to determine IPD values based on the first audio signal and the second audio signal, the IPD values represented using a first number of bits responsive to selection of the first IPD mode or represented using a second number of bits responsive to selection of the second IPD mode. |

Capping the rate of incoming transactions in inbound stateful conversations established in a distributed computing environment
The present invention relates to a method and a system for capping incoming transactions in inbound stateful conversations established between a client and a plurality of conversation servers of a service integrator. For each client, a group of conversation servers is allocated to handle the inbound stateful conversations initiated. Each conversation server in the group broadcasts a local traffic value periodically to the other conversation servers in the group. Each conversation server in the group calculates a transaction capping limit based on a client global transaction capping limit and the broadcasted local traffic values from the other conversation servers in the group. Each conversation server limits the rate of incoming transactions received by the client when exceeding the local transaction capping limit. |

Systems and methods for voice development frameworks
The present disclosure relates generally to a system and method for voice development frameworks. Certain cloud-based systems may be embodied in a multi-instance or multi-tenant framework, and may provide for certain computing systems and resources. For example, the cloud-based systems may provide for data repositories and the creation of executable objects, e.g., Flow Designer objects that include voice commands. In certain embodiments, visual development tools, including a Flow Designer system, may be used to create the executable objects, including voice command objects. For example, the Flow Designer system may enable the non-technical personnel to use natural language to more easily create and visualize objects and processes that automate certain tasks. |

Attention shifting of a robot in a group conversation using audio-visual perception based speaker localization
This disclosure relates to attention shifting of a robot in a group conversation with two or more attendees, wherein at least one of them is a speaker. State of the art has dealt with several aspects of Human-Robot Interaction (HRI) including responding to a source of sound at a time, addressing a fixed viewing area or determining who is the speaker based on eye gaze direction. However, attention shifting to make the conversation human-like is a challenge. The present disclosure uses audio-visual perception for speaker localization. Only qualified direction of arrivals (DOAs) are used for the audio perception. Further the audio perception is complimented by visual perception employing real time face detection and lip movement detection. Use of HRI rules, clustering of the DOAs, dynamic adjustment of rotation of the robot and a dynamically updated knowledge repository enriches the robot with intelligence to shift attention with minimum human intervention. |
