Did Bulgaria's economy change after the fall of communism?
4 answers
After the fall of communism in Bulgaria in 1989, significant changes occurred in the country's economy. Privatization led to a shift in ownership, with the state's direct ownership in top companies decreasing substantially, while foreign investors became major shareholders in many companies. Economic growth in Bulgaria has slowed down recently, although the country has been converging towards more advanced economies, with GDP growth averaging 2.3% and reaching half of the OECD's average disposable income per capita by 2019. However, Bulgaria's progress towards ecological transformation has been slow and ineffective, with studies showing inertia in transitioning to an ecological economy. Additionally, regulatory gaps have hindered the development of specific social enterprises in Bulgaria, impacting their potential for institutional change and compliance with policies.

What is the best hyperparameter tuning algorithm for LSTMs and BERT??
10 answers
Determining the "best" hyperparameter tuning algorithm for Long Short-Term Memory (LSTM) networks and BERT (Bidirectional Encoder Representations from Transformers) models involves considering various approaches and their effectiveness in optimizing model performance. For LSTMs, the introduction of two new algorithms for hyperparameter tuning alongside a fast Fourier transform (FFT)-based data decomposition technique has shown significant improvements in forecasting solar energy, with a notable increase in fitness and reduction in RMSE, suggesting a tailored approach for time series data like that generated by LSTMs. Particle Swarm Optimization (PSO) has also been applied to LSTM models, demonstrating its capability to minimize error prediction through effective hyperparameter selection, which includes optimization of weights, activation functions, and learning rates, thereby enhancing LSTM performance. On the other hand, for models like BERT, which are not explicitly covered in the provided contexts but share similarities with deep learning architectures discussed, techniques such as the Adaptive Teaching Learning Based (ATLB) Heuristic could potentially be adapted. This heuristic has been shown to identify optimal hyperparameters across various network architectures, including RNNs and LSTMs, by evaluating performance improvements on multiple datasets. Additionally, the Cost-Aware Pareto Region Bayesian Search (CARBS) presents a promising approach for tuning large models by performing local search around the performance-cost Pareto frontier, which could be particularly relevant for computationally intensive models like BERT. Moreover, the exploration of hyperparameter tuning using ConvLSTM, a variant of LSTM, suggests that methods such as grid search, Bayesian optimization, and genetic algorithms can be effective, with the potential for adaptation to BERT models given their deep learning foundation. The use of grammatical evolution for hyperparameter tuning further supports the notion of a flexible, model-agnostic approach that could benefit both LSTM and BERT models by allowing for the definition of custom search spaces. In conclusion, while there is no one-size-fits-all algorithm for hyperparameter tuning across all models, the effectiveness of specific algorithms like FFT-based techniques and PSO for LSTMs, and potentially ATLB Heuristic and CARBS for BERT-like models, highlights the importance of matching the tuning approach to the model's unique characteristics and computational demands.
How do these indicators differ between developed and developing countries?
4 answers
Indicators differ significantly between developed and developing countries. In the context of the 2008 global financial crisis, variables like growth rate and capital adequacy are leading indicators for developed economies, while inflation and industry development are crucial for developing countries. A study spanning a century from 1920 to 2020 shows that most developing countries have reduced their lag in indicators like education attainment and life expectancy compared to developed "benchmark" countries, with uneven progress across regions. Innovation indicators, crucial for economic growth, need to be customized for developing countries to accurately measure innovation performance, considering the different socio-economic structures present. Socio-economic indicators like GDP per capita and Human Development Index (HDI) highlight the widening gap between developed and developing countries, albeit at a slower rate, emphasizing the importance of social development alongside economic growth. Foreign Direct Investment (FDI) impacts environmental quality differently based on the origin of the investment, with FDI from developed economies being less influenced by host country factors compared to FDI from developing regions.
