Meeting Minutes from CellStrat AI Lab session on Saturday 28th Dec 2019 at Bengaluru
#CellStratAILab #disrupt4.0 #WeCreateAISuperstars
The last meetup of Year 2019 at the CellStrat AI Lab saw incredible presentations by our AI Lab Members.
First Sujith Kamath presented a superb session on Speech Recognition accompanied by a demo. Speech to Text Recognition is the buzz of the day. Though this area started 7 decades back, it has come to limelight now.
This session discussed the basics of Sound Signal including Amplitude, Wavelength, Cycle, Frequency, time-domain vs frequency-domain etc. Then Sujith covered how an Analog signal is converted to Digital by sampling at a certain sampling rate. He reviewed the Python libraries used for Audio to Digital Signal conversion.
The digitized signal is processed with a Convolutional network to recognize speech. He also explained how this model can run on live steams on AWS Cloud or Apache Kafka and Spark.
Next came an extensive session on Reinforcement Learning by Salim Ansari. The topic of Salim’s presentation was “Model-free Learning with Monte Carlo and Temporal-Difference Methods“. Dynamic Programming is an RL technique which falls under model-based RL. Salim’s session was focussed on Model-free learning which includes MC and TD techniques. The emphasis was on introducing the various methods used in RL for evaluating a given Tabular Policy. Monte Carlo methods require only experience, sample sequences of states, actions and rewards from actual or simulated interaction with the environment. Problem solving is based on averaging sample returns.
TD Learning is a combination of Monte Carlo and Dynamic Programming ideas. Like Monte Carlo methods, TD methods can learn directly from raw experience without a model of the environment’s dynamics. Like DP, TD methods update estimates based in part on other learned estimates, without waiting for a final outcome (they bootstrap).
