Anonymization means more than removing names.
Valuable data has to be removed, making the
training of personalized AI nearly impossible.

Is there a better
way to train AI?
WHAT NOW?

9. 9
Effective and Compliant
Training on non-anonymized
data in its silos
What we want

10. 10
Don’t consolidate user data through anonymization,
consolidate trained knowledge!
This approach is called
FEDERATED LEARNING
TRAIN SEPARATELY on every
data silo and COMBINE ALL
models for better model accuracy
How can we get this?

Federated Learning works in
three steps of continuous
iteration but has limitations
3 | Global Model
Distribution
The global model that XAIN
computes has higher
accuracy and is pushed back
to local training sites.
1 | Local
Training
All local models get
trained in local
customer environment
with local data.
2 | Model
Aggregation
Selected updated local models
are pushed to a platform
instance, which aggregates these
updates into a global model.
Limitations:
- Scalability when it comes to millions of local participants
- Full AI not compliant, as the Global Coordinator sees all local models

Our solution is framework &
model agnostic
↦Developers can install a simple SDK and
simply integrate a few lines of code into
any AI pipeline.
# Dataset
(x_train, y_train),(x_test, y_test) =
tf.keras.datasets.mnist.load_data()
data = (x_train / 255.0, y_test)
# Model
model = Sequential([
Flatten(input_shape=(28, 28)),
Dense(128, activation='relu'),
Dense(10, activation='softmax')
])
model.compile(optimizer='adam',
loss='sparse_categorical_crossentropy',
metrics=['accuracy'])
# XAIN

Benchmarking Results
⭑ Substantial gain offered by Federated Learning
over centralized ML
⭑ That gain is even greater if the data is
distributed in a very uneven fashion
1) IID: independent and identically distributed. Refers to same class data (e.g. accounting data, engine test data, etc.)

We monetize our Open Source
tech stack through a
Self-Service Platform
The XAIN Fully Managed Platform provides features to easily
integrate, monitor and manage Federated Learning projects.
↦Pricing is based on the number of integrated
SDKs and AI model sizes.

XAIN supports server
based and even edge
based models (mobile)
Under the California Consumer Privacy Act,
insurances cannot continue its current data
evaluation process for telematic insurances.
↦With XAIN, insurance providers can even
train risk models directly on user phones
and federate the learning.
