AI Forecasting Methods
for Investments Portfolio Optimization

• The Story - why AI for investing now
• General solution architecture
• Financial timeseries forecasting
• MCTS neural networks - portfolio optimization
• Summary
AGENDA

Alan Turing publishes “Computing
Machinery and Intelligence”.
Alan Turing creates his Turing Test to
determine whether or not a computer has
human-like intelligence.
The term AI was used later - in 1955 by
John McCarthy.
The birth of AI

Geoffrey Hinton coins the term deep
learning, to explain new algorithms that
empower computers to distinguish objects,
images and video.
Deep learning

A convolutional neural network designed by researchers at the University of Toronto
achieves an error rate of only 16% in the ImageNet Large Scale Visual Recognition
Challenge, a significant improvement over the 25% error rate achieved by the best
entry the year before.
Convolutional neural network

The side effect of so good efficiency in analysis and generating images and videos are
so called “deep fakes”, using AI for creating realistic images and videos.
Deep fake

The biggest success story of the year
was AlphaGo by DeepMind, a
Reinforcement Learning agent that
beats the world’s best Go
player Kie Je.
AlphaGo

Revolutionary reinforcement learning method which could achieve super human level
performance in GO, chess and shoggi without human knowledge.
AlphaZero

New, human attention based architecture
which achieves extraordinary results in
natural language translation.
Transformer

Never send human
to do AI machine job.
Science-fiction

It’s time to send AI
to do investing.
…became reality.

Algorithmic transaction systems

Based on the data, AI will learn both - the
method and patterns of the transaction
system.
AI transaction systems

• Algorithmic systems - the method and system parameters are
selected by human and therefore are deterministic
• AI – the system recognizes patterns, selects the method and
determines the parameters all by itself

FINANCIAL TIME SERIES FORECASTING

• Time series - ordered in time list of values of given attribute
• Time series forecasting - forecasting of future, not known values of time
series
• Hybrid time series forecasting methods - methods of time series
forecasting based on combination of machine learning and statistical
methods
Time series - definitions

• Regression: linear, logistic, polnynomial
• ARMA, ARIMA and different variants
• ARCH/GARCH - and different variants
• Exponential smoothing - Holt-Winters
• Theta method
• Ensemble of methods
Review of fundamental statistical forecasting methods

• M Competition - most prestigious and scientifically backed competition in time
series forecasting
• Organised by University of Nicosia and prof. Spyros Makridakis
• First and second place was won by hybrid methods
In the latest edition, M4 Competition was won by hybrid methods - combination of
statistical and machine learning methods. Accuracy has been evaluated on 100 000
of different time series.
M4 Competition - breakthrough in forecasting

• Data preprocessing - Exponential Smoothing
• Neural networks: LSTM - residual, dilated, attentions
• Model’s ensembling
• Parameters of preprocessing per each series, shared models
Data preprocessing and neural network LSTM in one dynamic computational
graph. Parameters of Exponential Smoothing are trained with neural networks
weight together.

ES Hybrid Method - winning method from M4

ES Hybrid Method - practical usage

• Unique and innovative approach for forecasting
• Stochastic Learning Automata algorithm for forecasting
• Dynamically managed probabilistic distributions
• Model’s ensembling
Dynamically learnt probabilistic distributions.
Tsetlin machines

• Chaotic time series forecasting
• Radom reservoir of neurons
• Input/output layers weights are only trained
• Neurons are connected together - no layers
Being trained is only input/output layer based on the random reservoir.
Echo State Networks

Echo State Networks

• Hybrid methods - ones of the most advanced class of forecasting methods
• For financial time series accuracy over 60% for long term
It very significant edge in investing.
Forecasting - summary
