I am working on bi LSTM.I have dataset comprises of 1720 samples with 6 features.When i set the size of sequence input layer (size of cell array) to 1, it gives me good accuracy but as i increases the size of input layer to 5 and 10, the accuracy decreases and training time also reduces. Kindly explain me why the size of input layer in LSTM has an affect on Accuracy?

Because the inputSize is equal to the number of used features (6 in your case). See documentation https://de.mathworks.com/help/deeplearning/ref/nnet.cnn.layer.sequenceinputlayer.html
