• Ability of machines to think and act rationallyArtificial
Intelligence
• Ability of machines to take decisions without
being explicitly programmed
• Traditional Machine Learning trains machines
based on labelled and classified data
Machines take decisions basis this data
Machine
Learning
• Machines that mimic human brain through
artificial neural networks capable of extracting
features and classifies from data
• Does not require pre-processing of data or
feature engineering

" Neural networks are models of the brain
and nervous system
" Highly parallel
" Process information more like the
brain than a serial computer
" Capable of learning – supervised and
unsupervised learning
" Applications:
" As powerful problem solvers
" In simulating complex human
functions like vision, text processing,
complex manoeuvres

Digital assistant such as Alexa or Siri or the supposedly mind-blowing Google Duplex
use a variety of technology including 1. Speech Processor System consisting of a DSP
or Digital Signal Processing Module 2. Pattern Recognition consisting of NLU (Natural
Language Understanding) and NLP (Natural Language Processing) to understand the
speech and 3. A Speech synthesis module based on NLG or Natural Language
Generation techniques.

" TensorFlow is a deep learning
framework adopted both in research
and production
" Open source software library for
numerical computation using data flow
graphs
" Originally developed by Google Brain
Team to conduct machine learning
research
" “TensorFlow is an interface for
expressing machine learning
algorithms, and an implementation for
executing such algorithms”
What Is TensorFlow?

10. Spotle.ai Study Material

Central Idea: Express a numeric computation as a graph.
● Graph nodes are operations which have any number of inputs
and outputs
● Graph edges are tensors which flow between nodes
TensorFlow – Central Idea

11. Spotle.ai Study Material

" The TensorFlow graph is a description of
computation
" The operators are placed on the graph
nodes
" It executes computations in a given
context of session
" A graph must be launched in a session
for any computation
" A session places the graph operations
onto devices such as CPU and GPU
" A session provides methods to execute
the graph operations

Spotle.ai/Learn
Visualization of graphs which is not an option with Scikit or Numpy
Portability - Computations can be deployed on multiple devices with single API
It is easily trainable for CPUs as well as GPUs for distributed computing
Allows parallel neural network training. Allows batch normalization and optimization of algorithms
Is open-source and backed by a large community of software engineers including Google
