-
Deep Learning & Specialized Techniques
6 weeksGoals
- Learn autoencoder architecture for anomaly detection.
- Explore advanced methods like Variational Autoencoders (VAEs) and GANs for anomaly detection.

- Research papers: Key papers on autoencoders for anomaly detection
- Project: Build a model to detect anomalies in system server metrics using an autoencoder
MilestoneCan design, train, and interpret deep learning-based anomaly detection models and implement basic drift detection in a pipeline.
-
MLOps & Production Engineering
6 weeksGoals
- Learn containerization with Docker.
- Understand cloud ML services (e.g., AWS SageMaker endpoints).
- Master workflow orchestration (Airflow) and experiment tracking (MLflow).
- Implement data validation and monitoring (Great Expectations, Evidently AI).
Resources
- Online course: 'MLOps Specialization' by DeepLearning.AI
- Cloud provider labs: AWS, GCP, or Azure free tier tutorials
- Project: Deploy your Phase 3 model as a REST API in a Docker container and schedule retraining with Airflow
MilestoneCan design and operate an end-to-end anomaly detection pipeline that is containerized, automated, monitored, and deployed in a cloud environment.
Practice Projects
Apply your skills with hands-on projects. Ordered by difficulty.
Credit Card Fraud Detection System
IntermediateBuild a model to identify fraudulent credit card transactions from a highly imbalanced dataset. Focus on precision/recall trade-offs and real-time scoring.
Server Log Anomaly Detector with Elasticsearch
IntermediateIngest and parse web server logs into Elasticsearch. Use unsupervised learning to detect unusual error patterns, traffic spikes, or suspicious IP activity.
IoT Sensor Failure Prediction
AdvancedUse a time-series dataset from industrial sensors to predict failures before they happen. Implement a forecasting model (e.g., Prophet, LSTM) and detect deviations from predictions.
LLM Output Hallucination Monitor
AdvancedCreate a system that monitors the outputs of a large language model for inconsistencies or hallucinations by cross-referencing with a knowledge base or using semantic similarity.
Network Intrusion Detection System (NIDS)
IntermediateAnalyze network packet data (e.g., from a pcap file) to detect anomalous patterns indicative of cyber attacks like port scans or DDoS.
