Here are the processing steps which we use for a basic HAR project using ML:

1. Data Collection:

• Smartphone Sensors: We gather data from accelerometer and gyroscope sensors from famous datasets like UCI HAR dataset.
• Video: To utilize videos we deploy other methods like optical flow.

2. Pre-processing the Data:

• Noise Filtering: For resolving the data we utilize a low-pass filter because raw sensor data always involves errors.
• Segmentation & Windowing: We split the consistent stream of data into constant size windows such as a 10-second window with 50% overlap.
• Feature Extraction: Retrieving statistical (mean, variance, etc.) and frequency-based (FFT coefficients) features from every window.

3. Framework Selection:

To select an applicable ML framework we implement some famous options for HAR like:

• Decision Trees
• Random Forests
• Support Vector Machines (SVM)
• Neural Networks such as LSTM and Convolutional Neural Networks (CNNs) assist us.

4. Training the Model:

• We divide the data into training and validation sets.
• Our system is trained on the training set.

5. Model Evaluation:

• On the validation set we check the framework’s efficiency.
• Accuracy, precision, F1-score and recall are the general metrics we employ in our model.

6. Deployment:

When we get satisfaction from our model we apply it in real-time applications like:

• Privacy: By detecting malicious behaviors we ensure security.
• Healthcare: We track patient’s events and predicting abnormalities.
• Sports: To observe a player’s performance we incorporate our model.

7. Extensions:

• Transfer Learning: Implementing a pre-trained model and we adjust it for HAR.
• Multi-modal Recognition: For increasing the accuracy we integrate data from several sensors and sources.
• Real-time Analyzing: We incorporate our model in real-world situations.

Tools & Libraries:

• Data Gathering & Pre-processing: Python with libraries such as Pandas and NumPy is helpful in our project.
• ML: Scikit-learn, TensorFlow and Keras are common options which support us.

Notes:

• It is important for us to make sure that the data is well-labeled and defines multiple situations. Because the quality of the data is challenging.
• For deep learning methods we utilize a huge dataset to increase efficiency.
• We practice with various structures and hyperparameters.
• By constantly retraining our model with fresh data it serves us in enhancing and handling the efficiency of the model.

We conclude that it is important to keep us updated with recent research in this area. The latest techniques and developments are consistently built in the field of HAR.
