1. A method for predicting affective response of a user to a stream of token instances, comprising:
- receiving the stream of token instances;
partitioning the stream of token instances into consecutive temporal windows of token instances;
wherein the temporal windows of token instances are ordered according to their start time;
predicting affective response of the user to a first temporal window of token instances by providing a machine learning-based predictor with input data comprising;
a vector of values derived from the first temporal window of token instances, and an initial state value derived from a value of a measurement channel of the user taken at time corresponding to start of the first temporal window of token instances; and
for each successive temporal window of token instances after the first temporal window of token instances;
predicting affective response of the user to the successive temporal window of token instances by providing the machine learning-based predictor with input data comprising;
a vector of values derived from the successive temporal window of token instances, and an initial state value derived from prediction of affective response of the user to a temporal window of token instances preceding the successive temporal window of token instances.

11. A system configured to predict an affective response of a user to a stream of token instances, comprising:
-
a sample generator configured to receive the stream of token instances, and to partition the stream of token instances into consecutive temporal windows of token instances;
wherein the temporal windows of token instances are ordered according to their start time; anda sequential machine learning-based predictor configured to receive input data comprising;
a vector of values derived from a first temporal window of token instances, and an initial state value derived from a value of a measurement channel of the user taken at time corresponding to start of the first temporal window of token instances; and
predict, based on the input data, an affective response of the user to the first temporal window of token instances; andfor each successive temporal window of token instances after the first temporal window of token instances, the sequential machine learning-based predictor is further configured to;
receive input data comprising;
a vector of values derived from the successive temporal window of token instances, and an initial state value derived from prediction of affective response of the user to a temporal window of token instances preceding the successive temporal window of token instances; and
to predict, based on the input data, an affective response of the user to the successive temporal window of token instances. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
