Here I answer to the question “Can I add a joke to a presentation or I’d better consider strict rules?”

At the HSE we have rules regarding style and formatting but if a graduate adds some pictures of jokes it fine since the joke is acceptable

You are the best! 🥰 We are 300+ and it my turn to act! Let’s schedule the lecture. What if we pick April, 16th 19:00 Moscow time?
The promised lecture 😊 will be held at 19:00 on the 16th of April.

Dear all, who don’t speak Russian let me know if you are willing to join. Probably I’d better do a separate English version? @Sam_Liu533 @bamper365

Dear HSE students, is there a course at the HSE that teaches you which viz to choose, what model quality metrics to apply and how to present your data analysis properly? Does the attached scheme look familiar to you?

Good day dear subscriber! Here is Argentex case briefly introduced by the Bloomberg. I suggest we can discuss it today (if we are having ou Jon C.Hull meeting as I proposed) 😅 If the majority of you is busy with your master thesis and projects let’s meet the next week

#course_trial@hunt4quant

Dear all!

One of my clients, a reputed financial institution, purchased an introductory course on ML models application to financial markets “All basic models used by banks and investment firms in 100 slides with no maths”



⚠️This is a brand new course ⚠️

I was given a permission to test the course with my students and I welcome you and any of your peers to join the webinar on May 13th at 18:00 Moscow time (in Russian).

🇬🇧
In fact my lecture is a translation from English to Russian (my client doesn’t speak English 😅) so I would be happy to give you the original lecture if we have enough listeners. If you prefer English version say it in comments, please. We will arrange a webinar.

⚠️ please bear in mind that this is 0% math lecture, feel free to bring those of your friends who are not familiar with formulas.


*Models I plan to consider today (in Russian!)*

1. Classification models:
1.1 Logit model
1.2.SVM
1.3 Decision trees: Random Forest, XGBoost
1.4 Neural Networks(MLP)

2. Regression
2.1 Linear Regression
2.2 Ridge
2.3 Lasso
2.4 kNN-regression
2.5 Decision trees
2.6 MLP

3. Time series analysis
3.1. ARIMA/SARIMA
3.2. ETS (Holt–Winters)
3.3 RNN (LSTM/GRU)
3.4 TCN
3.5 Seq2Seq + Attention

4. Anomalies détection
4.1 Isolation Forest
4.2 Autoencoder
4.3 Local Outlier Factor (LOF)
4.4 K-means / MiniBatch K-means
4.5 DBSCAN
4.6 Hierarchical Clustering

Hedging strategies:

1. Futures and options contracts - Buying put options for a long position
2. Futures and options contracts - Selling call options for coverage (covered call)
3. Correlation instruments - Covering risks through correlated assets (stocks ↔ ETF, currency)
4. Pair trading strategies - Long-Short by spread deviation

Diversification strategies:

1. Selecting assets with low/negative correlation
2. Balancing different classes (stocks, bonds, commodity futures)
3. Mathematical models
3.1 Markowitz: optimization through the covariance matrix
3.2 Risk Parity: equal risk for each position
4. Selection algorithms
4.1 Genetic algorithms for weight selection
4.2 CVaR optimization for "tail" risk
