Research Topic:

My Ph.D project focuses on the application of Machine Learning and Deep Learning techniques in the field of human activity recognition. In particular, my research focuses on the analysis and on the improvement of classification techniques based on inertial signals recorded by wearable devices.
Main contributions:

  • Improving traditional machine learning techniques exploiting personaliza- tion methods on metadata: differences within signals could prevent a one to one signal-class association. Intrinsic data grouping could be explored based on un- supervised statistical techniques, such as PCA, Clustering and DLA, or simply on taking into account metadata may highlight data similarities and differences. Based on that, I improved traditional machine learning techniques, such as SVM, AdaBoost, k-NN, by exploiting similarity between users signals data and between users physical attributes.
  • Comparison between traditional machine learning and deep learning techniques: differences between machine learning and deep learning techniques are mostly due to the feature extraction procedure. I investigate the performance ef- fects based on different sets of features selection. That is, Convolutional Neural Networ and Residual Neural Network were implemented and compared with SVM and k-NN.
  • Homogeneization and integration of public datasets: a plenty of labeled databases for machine learning and deep learning benchmarking are not consistent, both syn- tactically (e.g., different sampling frequency) and semantically (e.g., labels with different meanings). Coherent merging of existing databases would enable the evaluation of generalization capabilities of methods across databases and increase the number of labeled data. I propose a semi-automatic procedure to coherently merge existing databases based on signal and word similarity. Furthermore, I con- struct a platform for integrating and distributing heterogeneous data and models.
