    • Apparatus and methods for training and controlling of, for instance, robotic devices. In one implementation, a robot may be trained by a user using supervised learning. The user may be unable to control all degrees of freedom of the robot simultaneously. The user may interface to the robot via a control apparatus configured to select and operate a subset of the robot's complement of actuators. The robot may comprise an adaptive controller comprising a neuron network. The adaptive controller may be configured to generate actuator control commands based on the user input and output of the learning process. Training of the adaptive controller may comprise partial set training. The user may train the adaptive controller to operate first actuator subset. Subsequent to learning to operate the first subset, the adaptive controller may be trained to operate another subset of degrees of freedom based on user input via the control apparatus.

    • Event-based updates in artificial neuron networks may be implemented. An internal event may be defined in order to update incoming connections of a neuron. The internal event may be triggered by an external signal and/or internally by the neuron. A reinforcement signal may be used to trigger an internal event of a neuron in order to perform synaptic updates without necessitating post-synaptic response. An external event may be defined in order to deliver response of the neuron to desired targets. The external and internal events may be combined into a composite event configured to effectuate connection update and spike delivery to post-synaptic target. The scope of the internal event may comprise the respective neuron and does not extend to other neurons of the network. Conversely, the scope of the external event may extend to other neurons of the network via, for example, post-synaptic spike delivery.
    • 可以实现人造神经网络中基于事件的更新。 可以定义内部事件以便更新神经元的传入连接。 内部事件可能由外部信号和/或内部由神经元触发。 加强信号可以用于触发神经元的内部事件,以便执行突触更新,而不需要突触后响应。 可以定义外部事件以便将神经元的响应递送到期望的目标。 外部和内部事件可以组合成组合事件,配置为实现连接更新和尖峰传递到突触后目标。 内部事件的范围可以包括相应的神经元,并且不延伸到网络的其他神经元。 相反,外部事件的范围可以通过例如突触后尖峰传递来延伸到网络的其他神经元。

    • Efficient updates of connections in artificial neuron networks may be implemented. A framework may be used to describe the connections using a linear synaptic dynamic process, characterized by stable equilibrium. The state of neurons and synapses within the network may be updated, based on inputs and outputs to/from neurons. In some implementations, the updates may be implemented at regular time intervals. In one or more implementations, the updates may be implemented on- demand, based on the network activity (e.g., neuron output and/or input) so as to further reduce computational load associated with the synaptic updates. The connection updates may be decomposed into multiple event-dependent connection change components that may be used to describe connection plasticity change due to neuron input. Using event-dependent connection change components, connection updates may be executed on per neuron basis, as opposed to per- connection basis.
    • 可以实现人造神经网络中的连接的有效更新。 可以使用框架来描述使用以稳定平衡为特征的线性突触动态过程的连接。 可以基于对神经元的输入和输出来更新网络内的神经元和突触的状态。 在一些实现中,可以以规则的时间间隔来实现更新。 在一个或多个实现中,可以基于网络活动(例如,神经元输出和/或输入)按需实现更新,以便进一步减少与突触更新相关联的计算负荷。 连接更新可以被分解成多个依赖于事件的连接改变组件,其可以用于描述由神经元输入引起的连接可塑性变化。 使用与事件相关的连接更改组件,可以基于每个神经元执行连接更新,而不是基于每个连接。

    • Apparatus and methods for feedback in a spiking neural network. In one approach, spiking neurons receive sensory stimulus and context signal that correspond to the same context. When the stimulus provides sufficient excitation, neurons generate response. Context connections are adjusted according to inverse spike-timing dependent plasticity. When the context signal precedes the post synaptic spike, context synaptic connections are depressed. Conversely, whenever the context signal follows the post synaptic spike, the connections are potentiated. The inverse STDP connection adjustment ensures precise control of feedback- induced firing, eliminates runaway positive feedback loops, enables self-stabilizing network operation. In another aspect of the invention, the connection adjustment methodology facilitates robust context switching when processing visual information. When a context (such an object) becomes intermittently absent, prior context connection potentiation enables firing for a period of time. If the object remains absent, the connection becomes depressed thereby preventing further firing.
    • 用于在加标神经网络中反馈的装置和方法。 在一种方法中,刺激神经元接收对应于相同上下文的感觉刺激和上下文信号。 当刺激提供足够的激发时,神经元产生反应。 上下文连接根据反时限相关的可塑性进行调整。 当上下文信号在后突触尖端之前时,上下文突触连接被按下。 相反,只要上下文信号跟随突触后的尖峰,连接就被加强了。 逆STDP连接调整可确保精确控制反馈引发的触发,消除正反馈回路,实现自稳定网络运行。 在本发明的另一方面,当处理视觉信息时,连接调整方法有助于鲁棒的上下文切换。 当上下文(这样的对象)间歇地不存在时,先前的上下文连接增强使得能够触发一段时间。 如果物体不存在,则连接被压下,从而防止进一步的烧制。
