Abstract: An example method for abnormality detection based on causal graphs representing causal relationships of abnormalities includes detecting an abnormality in a test data set and generating a counterfactual data set for the test data set. The method further includes determining a quantitative feature dependence between the test data set and the counterfactual data set and determining a causal relationship of the abnormality based on the quantitative feature dependence. The method also includes generating a causal graph that represents the causal relationship of the abnormality. The method may also implement an action to mitigate the abnormality based on the causal graph.

Abstract: A novel and useful system and method of accelerated learning in neural networks using silicon based quantum dot arrays. Unitary noise is derived from a probability of detecting a particle within a quantum dot array structure comprising position based charge qubits with two time independent basis states |0> and |1>. A two level electron tunneling device such as an interface device, qubit or other quantum structure is used to generate quantum noise. The electron tunneling device includes a reservoir of particles, a quantum dot, and a barrier that is used to control tunneling between the reservoir and the quantum dot. Controlling the bias applied to the barrier controls the probability of detection. Thus, the probability density function (PDF) of the output unitary noise can be controlled to correspond to a desired probability. The quantum unitary noise is injected into one or more layers of an artificial neural network (ANN) to improve the learning and training process.

Abstract: A reinforcement learning (RL) based adaptive state observation model usable for implementing a brain machine interface (BMI) is proposed for decoding a brain signal to determine a movement action and controlling a machine to perform the movement action. In the model, the brain signal is processed by a neural network (NN) for applying a nonlinear mapping defined by NN weights to the brain signal to thereby yield a transformed brain signal. The NN learns the nonlinear mapping by RL, allowing the weights to be adaptively and continuously updated to follow nonlinearity and non-stationarity of the brain signal. The transformed brain signal is processed by a Kalman filter (KF) to yield a control signal for controlling the machine to perform the movement action, thereby utilizing the KF to provide smooth generation of the control signal while blocking adverse influence of nonlinearity and non-stationarity of the brain signal to the KF.

Abstract: A neural network processor is configured to execute instructions in parallel on different computing engines (CEs) to perform convolution operations on an input dataset. The input dataset is divided into overlapping chunks, including a first chunk and a second chunk. Each CE processes a last portion of a respective chunk to compute respective shared states and receives additional shared states for processing. The first chunk is the respective chunk for a first CE. The second chunk is the respective chunk for a second CE. The additional shared states received by the second CE are the respective shared states computed by the first CE. The second CE receives the respective shared states computed by the first CE as a substitute for intermediate states that would otherwise have been computed by the second CE using a first portion of the second chunk.
