The most significant risk that we face right now is the timeline for collecting the data and the robustness of the ML model. We hope to start collecting data next week which gives us ample time to collect more data if the initial dataset needs to be increased. Ricky also has plans for testing multiple different architectures and hyperparameters if the performance is insufficient. The other risk involves just keeping the readings consistent. This risk is being mitigated through some newly implemented calibration techniques and the introduction of a PCB.
The major change to the design is that we will as of now stick to the laptop as the main speaker component. This is due to our choice of ARDUINO which limits the speaker capability from the Arduino chip. We will circle back to this idea if time permits after testing and model tuning.
We will be proceeding with the original schedule. Ricky has adjusted a bit of his timeline to reflect some of the delays in Bluetooth integration and Ria has added the PCB creation timeline but it is relatively similar to the original schedule.
