In this paper, we perform hyper-parameters optimization using two popular methods: Tree Parzen Estimator (TPE) and Bayesian optimisation (BO) to predict vigilance states of individuals based on their EEG signal. The performance of the methods is evaluated on the vigilance states classification. ...
We used the categorical cross entropy loss function, and we trained the model with the Adam optimisation algorithm48 with the following parameters: \(beta_1=0.9\), \(beta_2=0.999\), batch size of 32, and a learning rate of 0.001 with a decay of 0.95 every 2 epochs. We tracked the ...
Human behaviour in this task was previously modelled with a number of explicit, theory-driven models, such as reward-oriented learning and decision making (q-learning), choosing some preferred pattern either for periods of exploration or all the time (reward oblivious behaviour)15,16,17. On one...
In this post, you will get a gentle introduction to the Adam optimization algorithm for use in deep learning. After reading this post, you will know: What the Adam algorithm is and some benefits of using the method to optimize your models. ...

Fig. 4. Reinforcement learning scheduling module in FogBus2 framework. • Reinforcement Learning Models: This sub-module contains the reinforcement learning models. According to Algorithm 1, we implement a DRLIS-based model. In addition, to evaluate the performance of DRLIS, we also implement DQ...
Ultrashort pulse laser drilling is a promising method for the fabrication of microchannels in dielectric materials. Due to the complexity of the process, there is a strong demand for numerical models (simulators) that can predict structures produced under specific processing conditions in order to rap...
Deep learning has recently gained popularity in digital pathology due to its high prediction quality. However, the medical domain requires explanation and insight for a better understanding beyond standard quantitative performance evaluation. Recently, many explanation methods have emerged. This work shows ...
