Vivek Singhal (Co-Founder & Chief Data Scientist, CellStrat) started with Clustering including K-means Clustering algorithm. Clustering is an unsupervised learning technique where we train a model to finds groups or cluster of items. K-means clustering (a type of Prototype-based method) trains by finding similarity between data samples and some chosen cluster centroids. It can involve hard clusters or soft clusters, in case of latter, some degree of uncertainty can be tolerated for each data sample.
There is also Agglomerative Clustering and Density Based Clustering. While K-means and Agglomerative is about finding circular clusters, Density based clustering can find non-circular and randomly shaped clusters – as is the case in Half Moons dataset.
In the afternoon session, Anshumaan Dash (Team Lead for Computer Vision) presented a deep-dive code demo on PyTorch. PyTorch was a DL library published by Facebook initially but now in open source domain.
Unlike TensorFlow, one can write high level / cleaner code for PyTorch. This is more akin to Keras, a high-level DL library which works on top of TensorFlow. However PyTorch is slightly more powerful than Keras in terms of flexibility and developer control. Here a neural network model and its forward pass is contained in a class called “Net“. Unlike TensorFlow, a Computation Graph need not be defined. Running the training step is also done with simplistic code in PyTorch compared to TensorFlow.
